CVE-2025-61587Public exploitNetwork attack vector

Open redirect via unrestricted Anubis redir parameter

Published Oct 1, 2025 · Updated Oct 1, 2025

Open redirect in Weblate before 5.13.3 allows remote attackers to send users to attacker-controlled sites via crafted links. The Anubis .within.website endpoint accepts the redir query value as an external destination when REDIRECT_DOMAINS is unset; Weblate's Docker NGINX template supplied only the request URI instead of a full same-origin URL. Exploitation requires an Anubis-integrated deployment with that allowlist absent and a victim who follows the crafted link, enabling phishing or a drive-by download.
