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.
OpenClaw before 2026.4.8 contains a request body replay vulnerability in fetchWithSsrFGuard that allows unsafe request bodies to be resent across cross-origin redirects. Attackers can exploit this by triggering redirects to exfiltrate sensitive request data or headers to unintended origins.
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.

CVE-2026-35396 is an Open Redirect vulnerability in the WeGIA web application versions prior to 3.6.9. The flaw exists in the /WeGIA/controle/control.php endpoint where the nextPage parameter is not properly validated when used with specific parameters, allowing attackers to redirect users to arbitrary external sites. This can facilitate phishing, credential theft, malware distribution, and social engineering attacks leveraging the trusted WeGIA domain. The vulnerability has a medium severity score of 5.1 and is fixed in version 3.6.9.
Homarr is an open-source dashboard. Prior to 1.57.0, a DOM-based Cross-Site Scripting (XSS) vulnerability has been discovered in Homarr's /auth/login page. The application improperly trusts a URL parameter (callbackUrl), which is passed to redirect and router.push. An attacker can craft a malicious link that, when opened by an authenticated user, performs a client-side redirect and executes arbitrary JavaScript in the context of their browser. This could lead to credential theft, internal network pivoting, and unauthorized actions performed on behalf of the victim. This vulnerability is fixed in 1.57.0.
SignalK Server versions prior to 2.24.0 contain a vulnerability in the OIDC login and logout handlers where the HTTP Host header is not validated. This allows an attacker to spoof the Host header to manipulate the OAuth2 redirect_uri, potentially stealing OAuth authorization codes and hijacking user sessions. The issue arises because the redirectUri configuration is unset by default, enabling injection of arbitrary domains. This vulnerability has been patched in version 2.24.0.
Red Hat has released an important security update for its build of Keycloak, version 26.2.15, addressing multiple vulnerabilities. These include information disclosure via redirect_uri validation bypass, replay of action tokens, UMA policy bypass allowing unauthorized resource access, privilege escalation through forged authorization codes, and denial of service via excessive OpenID Connect scope parameter processing. The update improves authentication and single sign-on security for web and mobile applications.
CVE-2026-2475 is an open redirect vulnerability in IBM Verify Identity Access Container versions 11.0 through 11.0.2 and IBM Security Verify Access Container versions 10.0 through 10.0.9.1. This flaw allows a remote attacker to craft a malicious URL that redirects users to arbitrary websites, potentially facilitating phishing attacks. The vulnerability requires user interaction and has a low attack complexity.
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.
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.
Ory Polis, formerly known as BoxyHQ Jackson, bridges or proxies a SAML login flow to OAuth 2.0 or OpenID Connect. Versions prior to 26.2.0 contain a DOM-based Cross-Site Scripting (XSS) vulnerability in Ory Polis's login functionality. The application improperly trusts a URL parameter (`callbackUrl`), which is passed to `router.push`. An attacker can craft a malicious link that, when opened by an authenticated user (or an unauthenticated user that later logs in), performs a client-side redirect and executes arbitrary JavaScript in the context of their browser. This could lead to credential theft, internal network pivoting, and unauthorized actions performed on behalf of the victim. Version 26.2.0 contains a patch for the issue.
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.
