Discourse: Open redirect via `sso_destination_url` cookie in `enter`

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.

FreeScout: Host Header Injection Leading to External Resource Loading and Open Redirect in FreeScout

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.

XenForo Open Redirect via getDynamicRedirect

XenForo before 2.2.17 and 2.3.1 allows open redirect via a specially crafted URL. The getDynamicRedirect() function does not adequately validate the redirect target, allowing attackers to redirect users to arbitrary external sites using crafted URLs containing newlines, user credentials, or host mismatches.

An issue pertaining to CWE-601: URL Redirection to Untrusted Site was discovered in Sunbird-Ed SunbirdEd-portal v1.13.4.

Keycloak: vulnerable redirect uri validation results in open redirec

A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.

Mastodon has a GET-Based Open Redirect via '/web/%2F<domain>'

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.

rhacs: Red Hat Advanced Cluster Security (ACS): Open Redirect and Content Spoofing via OAuth callback endpoint

A flaw was found in Red Hat Advanced Cluster Security (ACS). An unauthenticated remote attacker can exploit a vulnerability in the login interface's OAuth callback endpoint by crafting a malicious URL. This URL, containing unvalidated `error` and `error_uri` parameters, allows the attacker to display arbitrary error messages, leading to content spoofing. Furthermore, the attacker can redirect victims to malicious domains, effectively performing an open redirect under the guise of the trusted application's user interface.

AVideo has an Open Redirect via Unvalidated redirectUri in userLogin.php

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.

SuiteCRM has Unauthenticated Open Redirect in Leads WebToLead Capture

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.

@backstage/plugin-auth-backend: OAuth redirect URI allowlist bypass

Backstage is an open framework for building developer portals. Prior to 0.27.1, the experimental OIDC provider in @backstage/plugin-auth-backend is vulnerable to a redirect URI allowlist bypass. Instances that have enabled experimental Dynamic Client Registration or Client ID Metadata Documents and configured allowedRedirectUriPatterns are affected. A specially crafted redirect URI can pass the allowlist validation while resolving to an attacker-controlled host. If a victim approves the resulting OAuth consent request, their authorization code is sent to the attacker, who can exchange it for a valid access token. This requires victim interaction and that one of the experimental features is explicitly enabled, which is not the default. This vulnerability is fixed in 0.27.1.

Adobe Commerce | URL Redirection to Untrusted Site ('Open Redirect') (CWE-601)

Adobe Commerce versions 2.4.9-alpha3, 2.4.8-p3, 2.4.7-p8, 2.4.6-p13, 2.4.5-p15, 2.4.4-p16 and earlier are affected by a URL Redirection to Untrusted Site ('Open Redirect') vulnerability. An attacker could leverage this vulnerability to redirect users to malicious websites. Exploitation of this issue requires user interaction.
