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.","state":0,"publishedAt":"2025-10-30T17:08:12+00:00","modifiedAt":"2025-11-15T03:11:17+00:00","affected":[{"ecosystem":"Go","name":"github.com/TecharoHQ/anubis","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"},{"kind":"fixed","version":"1.23.0"}]}],"versions":[],"rawVersionEvidence":null}],"metrics":[{"system":"CVSS_V3","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:N","score":null,"severity":null},{"system":"CVSS_V4","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:P/VC:N/VI:N/VA:N/SC:L/SI:H/SA:N","score":null,"severity":null},{"system":"Publisher rating","vector":null,"score":null,"severity":"MODERATE"}],"references":["https://github.com/TecharoHQ/anubis/security/advisories/GHSA-cf57-c578-7jvv","https://nvd.nist.gov/vuln/detail/CVE-2025-64716","https://github.com/TecharoHQ/anubis/commit/7ed1753fcced351c81961bf520a7bfb2caac6e88","https://github.com/TecharoHQ/anubis","https://pkg.go.dev/vuln/GO-2025-4086"],"sourceUrl":"https://github.com/advisories/GHSA-cf57-c578-7jvv","license":"GitHub Advisory Database · CC-BY-4.0","key":"osv:GHSA-cf57-c578-7jvv","identifiers":["GHSA-cf57-c578-7jvv","CVE-2025-64716","GO-2025-4086"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
