{"id":"CVE-2025-64716","aliases":["GHSA-cf57-c578-7jvv","GO-2025-4086"],"url":"https://o3.security/vulnerability/CVE-2025-64716","summary":"Anubis vulnerable to possible XSS via redir parameter when using subrequest auth mode","details":"### Summary\n\nWhen using subrequest authentication, Anubis did not perform validation of the redirect URL and redirects user to any URL scheme. While most modern browsers do not allow a redirect to `javascript:` URLs, it could still trigger dangerous behavior in some cases.\n\n`GET https://example.com/.within.website/?redir=javascript:alert()` responds with `Location: javascript:alert()`.\n\n### Impact\n\nAnybody with a subrequest authentication seems affected. Using `javascript:` URLs will probably be blocked by most modern browsers, but using custom protocols for third-party applications might still trigger dangerous operations.\n\n### Note\n\nThis was originally reported by @mbiesiad against Weblate.","published":"2025-11-13T01:46:19.982Z","modified":"2026-10-28T02:30:36.810406866Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/TecharoHQ/anubis","fixedVersion":"1.23.0"}],"fix":{"url":"https://github.com/TecharoHQ/anubis/commit/7ed1753fcced351c81961bf520a7bfb2caac6e88","label":"TecharoHQ/anubis@7ed1753"},"references":[{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2025-4086"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/64xxx/CVE-2025-64716.json"},{"type":"ADVISORY","url":"https://github.com/TecharoHQ/anubis/security/advisories/GHSA-cf57-c578-7jvv"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-64716"},{"type":"FIX","url":"https://github.com/TecharoHQ/anubis/commit/7ed1753fcced351c81961bf520a7bfb2caac6e88"},{"type":"PACKAGE","url":"https://github.com/TecharoHQ/anubis"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:30:36.810406866Z"}}
