Flask-AppBuilder is an application development framework, built on top of Flask. In affected versions if using Flask-AppBuilder OAuth, an attacker can share a carefully crafted URL with a trusted domain for an application built with Flask-AppBuilder, this URL can redirect a user to a malicious site. This is an open redirect vulnerability. To resolve this issue upgrade to Flask-AppBuilder 3.2.2 or above. If upgrading is infeasible users may filter HTTP traffic containing `?next={next-site}` where the `next-site` domain is different from the application you are protecting as a workaround.

yaws before 2.0.4 does not attempt to address RFC 3875 section 4.1.18 namespace conflicts and therefore does not protect CGI applications from the presence of untrusted client data in the HTTP_PROXY environment variable, which might allow remote attackers to redirect a CGI application's outbound HTTP traffic to an arbitrary proxy server via a crafted Proxy header in an HTTP request, aka an "httpoxy" issue.

mod_auth_openidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In versions prior to 2.4.9, `oidc_validate_redirect_url()` does not parse URLs the same way as most browsers do. As a result, this function can be bypassed and leads to an Open Redirect vulnerability in the logout functionality. This bug has been fixed in version 2.4.9 by replacing any backslash of the URL to redirect with slashes to address a particular breaking change between the different specifications (RFC2396 / RFC3986 and WHATWG). As a workaround, this vulnerability can be mitigated by configuring `mod_auth_openidc` to only allow redirection whose destination matches a given regular expression.

A vulnerability was identified in Casdoor 2.356.0. Affected by this issue is some unknown functionality of the component OAuth Authorization Request Handler. Such manipulation of the argument redirect_uri leads to open redirect. It is possible to launch the attack remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

Adobe Experience Manager versions 6.5.24, LTS SP1, 2026.04 and earlier are affected by an Improper Redirect (Open Redirect) vulnerability that could lead to account takeover. An attacker could construct a malicious URL that redirects a victim to an attacker-controlled site. Exploitation of this issue requires user interaction in that a victim must click on a malicious link.

Open Redirect vulnerability in /c/portal/edit_info_item parameter redirect in Liferay Portal 7.4.3.86 through 7.4.3.131, and Liferay DXP 2024.Q3.1 through 2024.Q3.9, 2024.Q2.0 through 2024.Q2.13, 2024.Q1.1 through 2024.Q1.12 and 7.4 update 86 through update 92 allows an attacker to exploit this security vulnerability to redirect users to a malicious site.

Nextcloud is an open source content collaboration platform. From version 6.1.0 to before version 8.2.2, an attacker can craft links that would redirect users to another website, when the victim uses the attackers link to log in via user OIDC. This issue has been patched in version 8.2.2.

Roxy-WI is a web interface for managing Haproxy, Nginx, Apache and Keepalived servers. In versions 8.2.6.4 and prior, the login flow allow-lists next URLs by rejecting strings containing https:// or http:// substrings, then constructs https://{request.host}{next_url} and the JS client redirects via window.location.replace(). The block does not consider the userinfo@host syntax. next=@evil.example/path produces https://victim.example@evil.example/path, which all modern browsers route to evil.example. At time of publication, there are no publicly available patches.

Speakr is a personal, self-hosted web application designed for transcribing audio recordings. Prior to 0.8.20-alpha, the is_safe_url() helper used to validate post-login redirect targets applied urljoin(request.host_url, target) before parsing, while the controller passed the raw target to redirect(). A scheme-relative input such as ////evil.com resolved to a same-host URL during validation but was emitted verbatim in the Location header, where the browser interpreted it as a network-path-relative redirect to an attacker-controlled host. This vulnerability is fixed in 0.8.20-alpha.

Authlib is a Python library which builds OAuth and OpenID Connect servers. Prior to 1.6.12 and 1.7.1, an unauthenticated open redirect in Authlib's OpenIDImplicitGrant and OpenIDHybridGrant authorization endpoint lets a remote attacker cause the authorization server to issue an HTTP 302 to an attacker-chosen URL by submitting an authorization request that omits the openid scope. This vulnerability is fixed in 1.6.12 and 1.7.1.

An improper input validation vulnerability in FortiOS 6.2.1, 6.2.0, 6.0.8 and below until 5.4.0 under admin webUI may allow an attacker to perform an URL redirect attack via a specifically crafted request to the admin initial password change webpage.

An open redirect vulnerability exists in BF-630, BF-450M, BF-430, BF-431, BF631-W, BF830-W, Webpass, and SEMAC devices from CHIYU Technology that can be exploited by sending a link that has a specially crafted URL to convince the user to click on it.

The slashify package 1.0.0 for Node.js allows open-redirect attacks, as demonstrated by a localhost:3000///example.com/ substring.

n8n is an open source workflow automation platform. Prior to versions 1.123.32, 2.17.4, and 2.18.1, the /mcp-oauth/register endpoint accepted OAuth client registrations without authentication, allowing arbitrary redirect_uri values to be registered. When a user denies the MCP OAuth consent dialog, the handleDeny handler redirects the user to the registered redirect_uri without validation, enabling an open redirect to an attacker-controlled URL. An attacker can craft a phishing link and send it to a victim; if the victim clicks "Deny" on the consent page, they are silently redirected to an external site. This issue has been patched in versions 1.123.32, 2.17.4, and 2.18.1.

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.

Open redirect vulnerability in the System Settings in Liferay Portal 7.1.0 through 7.4.3.101, and Liferay DXP 2023.Q3.1 through 2023.Q3.4 , 7.4 GA through update 92, 7.3 GA through update 35, and older unsupported versions allows remote attackers to redirect users to arbitrary external URLs via the _com_liferay_configuration_admin_web_portlet_SystemSettingsPortlet_redirect parameter.

An open redirection vulnerability exists in multiple WSO2 products due to improper validation of the multi-option URL in the authentication endpoint when multi-option authentication is enabled. A malicious actor can craft a valid link that redirects users to an attacker-controlled site. By exploiting this vulnerability, an attacker may trick users into visiting a malicious page, enabling phishing attacks to harvest sensitive information or perform other harmful actions.

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.

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

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.

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.

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.

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.

In JetBrains TeamCity before 2025.11.3 open redirect was possible in the React project creation flow

Tenancy multi-tenant is an open source multi-domain controller for the Laravel web framework. In some situations, it is possible to have open redirects where users can be redirected from your site to any other site using a specially crafted URL. This is only the case for installations where the default Hostname Identification is used and the environment uses tenants that have `force_https` set to `true` (default: `false`). Version 5.7.2 contains the relevant patches to fix this bug. Stripping the URL from special characters to prevent specially crafted URL's from being redirected to. As a work around users can set the `force_https` to every tenant to `false`, however this may degrade connection security.

An open redirect vulnerability exists in django-allauth versions prior to 65.14.1 when SAML IdP initiated SSO is enabled (it is disabled by default), which may allow an attacker to redirect users to an arbitrary external website via a crafted URL.

Products.isurlinportal is a replacement for isURLInPortal method in Plone. Prior to versions 2.1.0, 3.1.0, and 4.0.0, a url /login?came_from=////evil.example may redirect to an external website after login. This issue has been patched in versions 2.1.0, 3.1.0, and 4.0.0.

Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to your services. From 2.0.0 to before 2.4.0, a flaw in callback URL validation allowed crafted redirect_uri values containing URL userinfo (@) to bypass legitimate callback pattern checks. If an attacker can trick a user into opening a malicious authorization link, the authorization code may be redirected to an attacker-controlled host. This vulnerability is fixed in 2.4.0.

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.

Due to an open redirect vulnerability in SAP NetWeaver Application Server ABAP, an unauthenticated attacker could craft a URL link embedding a malicious script at a location not properly sanitized. When a victim clicks on this link, the script executes within the victim's browser, redirecting them to a site controlled by the attacker. This allows the attacker to access and/or modify restricted information related to the web client. While the vulnerability poses no impact on data availability, it presents a considerable risk to confidentiality and integrity.

Feathersjs is a framework for creating web APIs and real-time applications with TypeScript or JavaScript. Versions 5.0.39 and below the redirect query parameter is appended to the base origin without validation, allowing attackers to steal access tokens via URL authority injection. This leads to full account takeover, as the attacker obtains the victim's access token and can impersonate them. The application constructs the final redirect URL by concatenating the base origin with the user-supplied redirect parameter. This is exploitable when the origins array is configured and origin values do not end with /. An attacker can supply @attacker.com as the redirect value results in https://target.com@attacker.com#access_token=..., where the browser interprets attacker.com as the host, leading to full account takeover. This issue has been fixed in version 5.0.40.

BigBlueButton is an open-source virtual classroom. In versions on the 3.x branch prior to 3.0.20, the string received with errorRedirectUrl lacks validation, using it directly in the respondWithRedirect function leads to an Open Redirect vulnerability. BigBlueButton 3.0.20 patches the issue. No known workarounds are available.
