In JetBrains TeamCity before 2021.2.1, a redirection to an external site was possible.

The wccp-pro WordPress plugin before 15.3 contains an open-redirect flaw via the referrer parameter, allowing redirection of users to external sites

Novu provides an API for sending notifications through multiple channels. Versions prior to 0.16.0 contain an open redirect vulnerability in the "Sign In with GitHub" functionality of Novu's open-source repository. It could have allowed an attacker to force a victim into opening a malicious URL and thus, potentially log into the repository under the victim's account gaining full control of the account. This vulnerability only affected the Novu Cloud and Open-Source deployments if the user manually enabled the GitHub OAuth on their self-hosted instance of Novu. Users should upgrade to version 0.16.0 to receive a patch.

Open redirect vulnerability in the Layout module's SEO configuration in Liferay Portal 7.4.3.70 through 7.4.3.76, and Liferay DXP 7.4 update 70 through 76 allows remote attackers to redirect users to arbitrary external URLs via the `_com_liferay_layout_admin_web_portlet_GroupPagesPortlet_backURL` parameter.

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Magazine3 Core Web Vitals & PageSpeed Booster.This issue affects Core Web Vitals & PageSpeed Booster: from n/a through 1.0.12.

Fuge CMS v1.0 contains an Open Redirect vulnerability in member/RegisterAct.java.

When choosing a site-isolated process for a document loaded from a data: URL that was the result of a redirect, Firefox would load that document in the same process as the site that issued the redirect. This bypassed the site-isolation protections against Spectre-like attacks on sites that host an "open redirect". Firefox no longer follows HTTP redirects to data: URLs. This vulnerability affects Firefox < 114.

Blackboard Learning and Community Portal System in Academic Suite 6.3.1.424, 6.2.3.23, and other versions before 6 allows remote attackers to redirect users to other URLs and conduct phishing attacks via a modified url parameter to frameset.jsp, which loads the URL into a frame and causes it to appear to be part of a valid page.

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Uncanny Owl Uncanny Toolkit for LearnDash.This issue affects Uncanny Toolkit for LearnDash: from n/a through 3.6.4.3.

Magento Long Term Support (LTS) is an unofficial, community-driven project provides an alternative to the Magento Community Edition e-commerce platform with a high level of backward compatibility. Prior to 20.18.0, Mage_ProductAlert_AddController::stockAction() reads the uenc query parameter and passes it directly to $this->_redirectUrl($backUrl) without calling $this->_isUrlInternal(). When the supplied product_id does not match any catalog product, the server issues an unvalidated HTTP 302 redirect to whatever URL was provided as uenc. This vulnerability is fixed in 20.18.0.

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.

A Spring MVC or Spring WebFlux application which configures a mapping for "/**" where the view name is not explicitly specified allows an attacker to craft a link resulting in a 302 redirect to an arbitrary external host via the redirect: prefix. Affected versions: Spring Framework 7.0.0 through 7.0.7; 6.2.0 through 6.2.18; 6.1.0 through 6.1.27; 5.3.0 through 5.3.48.

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.

Spring Security's CookieRequestCache and CookieServerRequestCache store the pre-authentication request URL in a browser cookie so that users can be redirected back to their intended destination after a successful login. In affected versions, the full absolute URL is stored in the cookie and is used without validation as the post-login redirect target. Affected versions: Spring Security 5.7.0 through 5.7.23; 5.8.0 through 5.8.25; 6.3.0 through 6.3.16; 6.4.0 through 6.4.16; 6.5.0 through 6.5.10; 7.0.0 through 7.0.5.

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in PluginOps MailChimp Subscribe Form, Optin Builder, PopUp Builder, Form Builder.This issue affects MailChimp Subscribe Form, Optin Builder, PopUp Builder, Form Builder: from n/a through 4.0.9.3.

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.

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.

Landscape allowed URLs which caused 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.

Avaya IX Workforce Engagement v15.2.7.1195 - CWE-601: URL Redirection to Untrusted Site ('Open Redirect')

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.

The O2 Business application 1.2.0 for Android exposes the canvasm.myo2.SplashActivity activity to other applications. The purpose of this activity is to handle deeplinks that can be delivered either via links or by directly calling the activity. However, the deeplink format is not properly validated. This can be abused by an attacker to redirect a user to any page and deliver any content to the user.

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.

IFTOP developed by WellChoose has an Open redirect vulnerability, allowing authenticated remote attackers to craft a URL that tricks users into visiting malicious website.

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in Dylan James Zephyr Project Manager.This issue affects Zephyr Project Manager: from n/a through 3.3.9.

Devices using Snap One OvrC cloud are sent to a web address when accessing a web management interface using a HTTP connection. Attackers could impersonate a device and supply malicious information about the device’s web server interface. By supplying malicious parameters, an attacker could redirect the user to arbitrary and dangerous locations on the web.

XWiki Platform is a generic wiki platform offering runtime services for applications built on top of it. In versions prior to 14.10.4 it's possible to exploit well known parameters in XWiki URLs to perform redirection to untrusted site. This vulnerability was partially fixed in the past for XWiki 12.10.7 and 13.3RC1 but there is still the possibility to force specific URLs to skip some checks, e.g. using URLs like `http:example.com` in the parameter would allow the redirect. The issue has now been patched against all patterns that are known for performing redirects. This issue has been patched in XWiki 14.10.4 and 15.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

CrushFTP through 8.3.0 is vulnerable to credentials theft via URL redirection.

Redash is a package for data visualization and sharing. In Redash version 10.0 and prior, the implementation of Google Login (via OAuth) incorrectly uses the `state` parameter to pass the next URL to redirect the user to after login. The `state` parameter should be used for a Cross-Site Request Forgery (CSRF) token, not a static and easily predicted value. This vulnerability does not affect users who do not use Google Login for their instance of Redash. A patch in the `master` and `release/10.x.x` branches addresses this by replacing `Flask-Oauthlib` with `Authlib` which automatically provides and validates a CSRF token for the state variable. The new implementation stores the next URL on the user session object. As a workaround, one may disable Google Login to mitigate the vulnerability.

The Protect WP Admin WordPress plugin before 4.0 discloses the URL of the admin panel via a redirection of a crafted URL, bypassing the protection offered.

URL Redirection to Untrusted Site ('Open Redirect') vulnerability in CRM Perks Integration for HubSpot and Contact Form 7, WPForms, Elementor, Ninja Forms.This issue affects Integration for HubSpot and Contact Form 7, WPForms, Elementor, Ninja Forms: from n/a through 1.2.8.

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.

Nagios XI 2024R1.2.2 is vulnerable to an open redirect flaw on the Tools page, exploitable by users with read-only permissions. This vulnerability allows an attacker to craft a malicious link that redirects users to an arbitrary external URL without their consent.

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.

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.

open redirect in pollbot (pollbot.services.mozilla.com) in versions before 1.4.6

Open Redirect on Rudloff/alltube in Packagist rudloff/alltube prior to 3.0.1.

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.

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.

Open Redirect in GitHub repository medialize/uri.js prior to 1.19.10.

An Open Redirect vulnerability exists prior to version 1.52.117, where the built-in QR scanner in Brave Browser Android navigated to scanned URLs automatically without showing the URL first. Now the user must manually navigate to the URL.

URL Confusion When Scheme Not Supplied in GitHub repository medialize/uri.js prior to 1.19.11.

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.

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.
