Common/Grav.php in Grav before 1.7 has an Open Redirect. This is partially fixed in 1.6.23 and still present in 1.6.x.

The Rank Math plugin through 1.0.40.2 for WordPress allows unauthenticated remote attackers to create new URIs (that redirect to an external web site) via the unsecured rankmath/v1/updateRedirection REST API endpoint. In other words, this is not an "Open Redirect" issue; instead, it allows the attacker to create a new URI with an arbitrary name (e.g., the /exampleredirect URI).

An issue was discovered in xdLocalStorage through 2.0.5. The buildMessage() function in xdLocalStorage.js specifies the wildcard (*) as the targetOrigin when calling the postMessage() function on the iframe object. Therefore any domain that is currently loaded within the iframe can receive the messages that the client sends.

authentik is an open-source identity provider. Prior to version 2026.2.3, the WS-Federation provider validates the user-supplied wreply parameter using a raw string prefix check rather than proper URL parsing. An attacker who can craft a login link can supply a wreply value on a different origin that passes the check (e.g. https://portal.example.com.evil.tld/), causing the victim's browser to POST the signed WS-Federation login response to attacker-controlled infrastructure. This issue has been patched in version 2026.2.3.

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.6.10 and 1.7.1, Authlib's OAuth 2.0 authorization endpoint can be turned into an unauthenticated open redirect when a request uses an unsupported response_type and supplies an attacker-controlled redirect_uri. The vulnerable behavior happens before client lookup and before any redirect URI validation. As a result, an attacker does not need a valid client registration, an authenticated user, or any prior state. A single request to the authorization endpoint is enough to obtain a 302 Location response to an arbitrary attacker-controlled URL. This vulnerability is fixed in 1.6.10 and 1.7.1.

In GLPI before version 9.4.6, there is a vulnerability that allows bypassing the open redirect protection based which is based on a regexp. This is fixed in version 9.4.6.

LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. Prior to 27.0.3 and 28.0.1, the redirect parameter upon login to LORIS was not validating the value of the redirect as being within LORIS, which could be used to trick users into visiting arbitrary URLs if they are given a link with a third party redirect parameter. This vulnerability is fixed in 27.0.3 and 28.0.1.

resources/src/mediawiki.page.ready/ready.js in MediaWiki before 1.35 allows remote attackers to force a logout and external redirection via HTML content in a MediaWiki page.

Drupal versions 5.x and 6.x has open redirection

Devise is an authentication solution for Rails based on Warden. In versions 5.0.3 and below, when the Timeoutable module is enabled in Devise, the FailureApp#redirect_url method returns request.referrer — the HTTP Referer header, which is attacker-controllable — without validation for any non-GET request that results in a session timeout. An attacker who hosts a page with an auto-submitting cross-origin form can cause a victim with an expired Devise session to be redirected to an arbitrary external URL. This contrasts with the GET timeout path (which uses server-side attempted_path) and Devise's own store_location_for mechanism (which strips external hosts via extract_path_from_location), both of which are protected; only the non-GET timeout redirect path is unprotected. Expired-session users can be silently redirected from the trusted app domain to attacker-controlled URLs, enabling phishing and malware delivery while bypassing browser warnings. Note: Rails' built-in open-redirect protection does not mitigate this issue. Devise::FailureApp is an ActionController::Metal app with its own isolated copy of the relevant redirect configuration, so config.action_controller.action_on_open_redirect = :raise (and the older raise_on_open_redirects setting) do not reach it. This issue has been fixed in version 5.0.4.

React Router is a router for React. In versions 7.0.0 through 7.14.0 and 6.7.0 through 6.30.3, certain URLs passed to the redirect function can trigger an open redirect to an external domain due to path values starting with // being reinterpreted as protocol-relative URLs. The level of impact depends on the validation done by the application prior to returning the redirect. This does not impact applications using Declarative Mode (<BrowserRouter>). This is patched in versions 7.14.1 and 6.30.4.

In OAuth2 Proxy before 5.1.1, there is an open redirect vulnerability. Users can provide a redirect address for the proxy to send the authenticated user to at the end of the authentication flow. This is expected to be the original URL that the user was trying to access. This redirect URL is checked within the proxy and validated before redirecting the user to prevent malicious actors providing redirects to potentially harmful sites. However, by crafting a redirect URL with HTML encoded whitespace characters the validation could be bypassed and allow a redirect to any URL provided. This has been patched in 5.1.1.

Cacti is an open source performance and fault management framework. Versions 1.2.30 and prior are vulnerable to Open Redirect through a substring check rather than a host check at str_contains($referer, CACTI_PATH_URL). When the user's login_opts == '1' (redirect to referer after login), the function used $_SERVER['HTTP_REFERER'] directly. An attacker could craft a referer such as https://evil.com/cacti/. Where CACTI_PATH_URL is /cacti/, the substring matches and the user is redirected to evil.com after login. The pre-existing validate_redirect_url() helper at lib/html_utility.php performed proper validation but was not invoked from auth_login_redirect(). This issue has been fixed in version 1.2.31.

Spring Security Authorization Server's authorization endpoint performs insufficient validation of the request_uri parameter. An attacker can craft a malicious authorization request containing an invalid request_uri and an arbitrary, unvalidated redirect_uri, which can lead to an Open Redirect vulnerability. Affected versions: Spring Security 7.0.0 through 7.0.5. Spring Authorization Server 1.5.0 through 1.5.7.

AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. In @adonisjs/http-server versions prior to 7.8.1 and 8.0.0-next.0 through 8.1.3, and @adonisjs/core versions prior to 7.4.0, the response.redirect().back() method reads the Referer header from the incoming HTTP request and redirects to that URL without validating the host.An attacker who can influence the Referer header can cause the application to redirect users to a malicious external site. This affects all AdonisJS applications that use response.redirect().back() or response.redirect('back'). This issue has been fixed in versions 7.8.1 and 8.2.0 and 7.4.0 of @adonisjs/core.

The WP Compress – Image Optimizer [All-In-One plugin for WordPress is vulnerable to Open Redirect in all versions up to, and including, 6.20.01. This is due to insufficient validation on the redirect url supplied via the 'css' parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

The Payment Gateway for Telcell WordPress plugin through 2.0.1 does not validate the api_url parameter before redirecting the user to its value, leading to an Open Redirect issue

A flaw was found in Keycloak. This issue may allow an attacker to steal authorization codes or tokens from clients using a wildcard in the JARM response mode "form_post.jwt" which could be used to bypass the security patch implemented to address CVE-2023-6134.

The Analytics Insights for Google Analytics 4 (AIWP) WordPress plugin before 6.3 is vulnerable to Open Redirect due to insufficient validation on the redirect oauth2callback.php file. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

WeGIA is a Web manager for charitable institutions. Prior to 3.6.9, an Open Redirect vulnerability was identified in the /WeGIA/controle/control.php endpoint of the WeGIA application, specifically through the nextPage parameter when combined with metodo=listarTodos & listarId_Nome and nomeClasse=OrigemControle. The application fails to validate or restrict the nextPage parameter, allowing attackers to redirect users to arbitrary external websites. This can be abused for phishing attacks, credential theft, malware distribution, and social engineering using the trusted WeGIA domain. This vulnerability is fixed in 3.6.9.

Open Redirect vulnerability in FireEye HXTool affecting version 4.6, the exploitation of which could allow an attacker to redirect a legitimate user to a malicious page by changing the 'redirect_uri' parameter.

The Travelpayouts: All Travel Brands in One Place WordPress plugin through 1.1.15 is vulnerable to Open Redirect due to insufficient validation on the travelpayouts_redirect variable. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

Open edX Platform enables the authoring and delivery of online learning at any scale. The view_survey endpoint accepts a redirect_url GET parameter that is passed directly to HttpResponseRedirect() without any URL validation. When a non-existent survey name is provided, the server issues an immediate HTTP 302 redirect to the attacker-controlled URL. Additionally, the same unvalidated URL is embedded in a hidden form field and returned in a JSON response after form submission, where client-side JavaScript performs location.href = url. This enables phishing and credential theft attacks against authenticated Open edX users. This vulnerability is fixed with commit 76462f1e5fa9b37d2621ad7ad19514b403908970.

WeGIA is a Web manager for charitable institutions. Prior to 3.6.9, an Open Redirect vulnerability was identified in the /WeGIA/controle/control.php endpoint of the WeGIA application, specifically through the nextPage parameter when combined with metodo=listarId and nomeClasse=IsaidaControle. The application fails to validate or restrict the nextPage parameter, allowing attackers to redirect users to arbitrary external websites. This can be abused for phishing attacks, credential theft, malware distribution, and social engineering using the trusted WeGIA domain. This vulnerability is fixed in 3.6.9.

WeGIA is a Web manager for charitable institutions.

The application fails to validate or restrict the nextPage parameter, allowing attackers to redirect users to arbitrary external websites. This can be abused for phishing attacks, credential theft, malware distribution, and social engineering using the trusted WeGIA domain. This vulnerability is fixed in 3.6.9.

hoppscotch is an open source API development ecosystem. Prior to version 2026.3.0, the /enter page contains a DOM-based open redirect vulnerability. The redirect query parameter is directly used to construct a URL and redirect the user without proper validation. This issue has been patched in version 2026.3.0.

An issue existed in the parsing of URL schemes. This issue was addressed with improved URL validation. This issue is fixed in Shazam Android App Version 9.25.0, Shazam iOS App Version 12.11.0. Processing a maliciously crafted URL may lead to an open redirect.

WeGIA is a Web manager for charitable institutions. Prior to 3.6.9, open redirect has been found in WeGIA webapp. The redirect parameter is taken directly from $_GET with no URL validation or whitelist check, then used verbatim in a header("Location: ...") call. This vulnerability is fixed in 3.6.9.

Vulnerability in the Oracle Identity Manager product of Oracle Fusion Middleware (component: Identity Console). Supported versions that are affected are 12.2.1.4.0 and 14.1.2.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle Identity Manager. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Identity Manager, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle Identity Manager accessible data as well as unauthorized read access to a subset of Oracle Identity Manager accessible data. CVSS 3.1 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

Statamic is a Laravel and Git powered content management system (CMS). Prior to versions 5.73.16 and 6.7.2, the external URL detection used for redirect validation on unauthenticated endpoints could be bypassed, allowing users to be redirected to external URLs after actions like form submissions and authentication flows. This has been fixed in 5.73.16 and 6.7.2.

FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to version 1.8.211, host header manipulation in FreeScout version (http://localhost:8080/system/status) allows an attacker to inject an arbitrary domain into generated absolute URLs. This leads to External Resource Loading and Open Redirect behavior. When the application constructs links and assets using the unvalidated Host header, user requests can be redirected to attacker-controlled domains and external resources may be loaded from malicious servers. This issue has been patched in version 1.8.211.

Mastodon is a free, open-source social network server based on ActivityPub. Prior to versions 4.5.8, 4.4.15, and 4.3.21, an unauthenticated Open Redirect vulnerability (CWE-601) exists in the `/web/*` route due to improper handling of URL-encoded path segments. An attacker can craft a specially encoded URL that causes the application to redirect users to an arbitrary external domain, enabling phishing attacks and potential OAuth credential theft. The issue occurs because URL-encoded slashes (`%2F`) bypass Rails path normalization and are interpreted as host-relative redirects. Versions 4.5.8, 4.4.15, and 4.3.21 patch the issue.

Signal K Server is a server application that runs on a central hub in a boat. Prior to version 2.24.0, SignalK Server contains a code-level vulnerability in its OIDC login and logout handlers where the unvalidated HTTP Host header is used to construct the OAuth2 redirect_uri. Because the redirectUri configuration is silently unset by default, an attacker can spoof the Host header to steal OAuth authorization codes and hijack user sessions in realistic deployments as The OIDC provider will then send the authorization code to whatever domain was injected. This issue has been patched in version 2.24.0.

Due to an Open Redirect vulnerability in SAP NetWeaver Application Server ABAP, an unauthenticated attacker could craft malicious URL that, if accessed by a victim, they could be redirected to the page controlled by the attacker. This causes low impact on confidentiality and integrity of the application with no impact on availability.

Lack of "current" GET parameter validation during the action of changing a language leads to an open redirect vulnerability.

The WordPress Toolbar WordPress plugin through 2.2.6 redirects to any URL via the "wptbto" parameter. This makes it possible for unauthenticated attackers to redirect users to potentially malicious sites if they can successfully trick them into performing an action.

JupyterHub is software that allows one to create a multi-user server for Jupyter notebooks. Prior to version 5.4.4, an open redirect vulnerability in JupyterHub allows attackers to construct links which, when clicked, take users to the JupyterHub login page, after which they are sent to an arbitrary attacker-controlled site outside JupyterHub instead of a JupyterHub page, bypassing JupyterHub's check to prevent this. This issue has been patched in version 5.4.4.

Open redirect vulnerability has been found in the Open CMS product affecting versions 14 and 15 of the 'Mercury' template. An attacker could create a specially crafted URL and send it to a specific user to redirect them to a malicious site and compromise them. Exploitation of this vulnerability is possible due to the fact that there is no proper sanitization of the 'URI' parameter.

A CWE-601 URL Redirection to Untrusted Site vulnerability exists that could cause an openredirect vulnerability leading to a cross site scripting attack. By providing a URL-encoded input attackers can cause the software’s web application to redirect to the chosen domain after a successful login is performed.

The Angular SSR is a server-rise rendering tool for Angular applications. Versions on the 22.x branch prior to 22.0.0-next.2, the 21.x branch prior to 21.2.3, and the 20.x branch prior to 20.3.21 have an Open Redirect vulnerability in `@angular/ssr` due to an incomplete fix for CVE-2026-27738. While the original fix successfully blocked multiple leading slashes (e.g., `///`), the internal validation logic fails to account for a single backslash (`\`) bypass. When an Angular SSR application is deployed behind a proxy that passes the `X-Forwarded-Prefix` header, an attacker provides a value starting with a single backslash, the internal validation failed to flag the single backslash as invalid, the application prepends a leading forward slash, resulting in a `Location` header containing the URL, and modern browsers interpret the `/\` sequence as `//`, treating it as a protocol-relative URL and redirecting the user to the attacker-controlled domain. Furthermore, the response lacks the `Vary: X-Forwarded-Prefix` header, allowing the malicious redirect to be stored in intermediate caches (Web Cache Poisoning). Versions 22.0.0-next.2, 21.2.3, and 20.3.21 contain a patch. Until the patch is applied, developers should sanitize the `X-Forwarded-Prefix` header in their `server.ts` before the Angular engine processes the request.

A CWE-601:URL Redirection to Untrusted Site (‘Open Redirect’) vulnerability exists that could cause disclosure of information through phishing attempts over HTTP.

Chamilo LMS is a learning management system. Prior to 1.11.38 and 2.0.0-RC.3, an Open Redirect vulnerability in the session course edit page allows an attacker to redirect an authenticated administrator to an arbitrary external URL after saving coach assignment changes. The redirect also leaks the id_session parameter to the attacker's server. This vulnerability is fixed in 1.11.38 and 2.0.0-RC.3.

WBCE CMS 1.6.1 contains a cross-site scripting vulnerability that allows attackers to inject malicious HTML and CSS to capture user keystrokes. Attackers can upload a crafted HTML file with CSS-based keylogging techniques to intercept password characters through background image requests.

WWBN AVideo is an open source video platform. Prior to version 26.0, WWBN/AVideo contains an open redirect vulnerability in the login flow where a user-supplied redirectUri parameter is reflected directly into a JavaScript `document.location` assignment without JavaScript-safe encoding. After a user completes the login popup flow, a timer callback executes the redirect using the unvalidated value, sending the victim to an attacker-controlled site. Version 26.0 fixes the issue.

Open Redirect in GitHub repository mosparo/mosparo prior to 1.0.2.

Discourse is an open-source discussion platform. From versions 2026.1.0-latest to before 2026.1.3, 2026.2.0-latest to before 2026.2.2, and 2026.3.0-latest to before 2026.3.0, the enter action in StaticController reads the sso_destination_url cookie and redirects to it with allow_other_host: true without validating the destination URL. While this cookie is normally set during legitimate DiscourseConnect Provider flows with cryptographically validated SSO payloads, cookies are client-controlled and can be set by attackers. This issue has been patched in versions 2026.1.3, 2026.2.2, and 2026.3.0.

Sylius is an Open Source eCommerce Framework on Symfony. CurrencySwitchController::switchAction(), ImpersonateUserController::impersonateAction() and StorageBasedLocaleSwitcher::handle() use the HTTP Referer header directly when redirecting. The attack requires the victim to click a legitimate application link placed on an attacker-controlled page. The browser automatically sends the attacker's site as the Referer, and the application redirects back to it. This can be used for phishing or credential theft, as the redirect originates from a trusted domain. The severity varies by endpoint; public endpoints require no authentication and are trivially exploitable, while admin-only endpoints require an authenticated session but remain vulnerable if an admin follows a link from an external source such as email or chat. The issue is fixed in versions: 1.9.12, 1.10.16, 1.11.17, 1.12.23, 1.13.15, 1.14.18, 2.0.16, 2.1.12, 2.2.3 and above.

SuiteCRM is an open-source, enterprise-ready Customer Relationship Management (CRM) software application. Prior to versions 7.15.1 and 8.9.3, SuiteCRM contains an unauthenticated open redirect vulnerability in the WebToLead capture functionality. A user-supplied POST parameter is used as a redirect destination without validation, allowing attackers to redirect victims to arbitrary external websites. This vulnerability allows attackers to abuse the trusted SuiteCRM domain for phishing and social engineering attacks by redirecting users to malicious external websites. Versions 7.15.1 and 8.9.3 patch the issue.

Dell PowerFlex Manager, versions 4.6.2 and prior, contains an Open Redirect Vulnerability. An unauthenticated attacker could potentially exploit this vulnerability, leading to a targeted application user being redirected to arbitrary web URLs. The vulnerability could be leveraged by attackers to conduct phishing attacks that cause users to divulge sensitive information.

Brave Browser before 1.59.40 does not properly restrict the schema for WebUI factory and redirect. This is related to browser/brave_content_browser_client.cc and browser/ui/webui/brave_web_ui_controller_factory.cc.
