CVE-2026-404655.3 MED3.6%
——1NSP is vulnerable to an open redirect due to insufficient server-side validation of the URL (or redirect) parameter.4hCVE-2026-824674.7 MED8.7%
——3Rodauth before 2.47.0 fails to validate protocol-relative return-to paths in confirm_password, login_return_to_requested_location, and two_factor_auth_return_to_requested_location features. Attackers can craft paths with leading double slashes that browsers resolve as protocol-relative URLs, redirecting authenticated users to attacker-controlled sites after login or password confirmation.2hCVE-2026-824646.1 MED9.8%
——3pac4j-core before 6.5.6 contains an open redirect vulnerability in DefaultLogoutLogic.perform() that accepts backslash-prefixed logout redirect targets matching logoutUrlPattern. Attackers can craft logout links with backslash-prefixed external hosts that browsers normalize into network-path references, redirecting victims to attacker-controlled sites after logout.2dCVE-2026-813424.7 MED6.6%
——2The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.43 does not validate a redirect parameter supplied during user registration before using it, allowing unauthenticated attackers to redirect users to arbitrary external URLs.2dCVE-2026-822744.7 MED12.6%
——4Twenty through 2.35.0 contains an open redirect vulnerability in the OAuthPropagatorController.propagateOAuthCallback endpoint that treats the state query parameter as a redirect URL. Attackers can craft malicious requests to redirect users to arbitrary hosts while forwarding OAuth authorization codes, bypassing domain validation when IS_MULTIWORKSPACE_ENABLED is disabled.3dCVE-2026-558344.3 MED18.7%
——6Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to services. From 2.6.0 until 2.9.0, frontend/src/routes/authorize/+page.ts reads the redirect_uri query parameter and frontend/src/routes/authorize/+page.svelte uses the raw callbackURL in redirectWithError when prompt=none cannot complete silent authorization. The client-side path only blocks javascript and data schemes and does not invoke the backend callback allow-list validation, so an unauthenticated attacker who knows a valid client_id can redirect a victim browser to an arbitrary HTTP or HTTPS origin for phishing or OIDC error and state smuggling. This issue is fixed in version 2.9.0.3d
