{"id":"CVE-2026-50552","aliases":["GHSA-jr4p-4xjh-fwvw"],"url":"https://o3.security/vulnerability/CVE-2026-50552","summary":"Koel: Server-Side Request Forgery (SSRF) in radio station creation due to missing validation bail","details":"Koel is a free, open-source music streaming solution. Prior to version 9.7.1, Koel contains a Server-Side Request Forgery (SSRF) vulnerability in the radio station creation endpoint (POST /api/radio/stations). The url field validation rules are declared without the bail keyword, so the HasAudioContentType rule — which issues HTTP requests to the supplied URL — still executes even after the SafeUrl rule has rejected the URL as pointing to a private/reserved address. Any authenticated, non-admin user can therefore coerce the server into making HEAD/GET requests to arbitrary internal hosts. This issue has been patched in version 9.7.1.","published":"2026-06-12T18:51:46.028Z","modified":"2026-08-12T03:51:11.843171498Z","cvss":{"score":6.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L"},"epss":{"score":0.00169,"percentile":0.0649,"asOf":"2026-09-06"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Packagist","name":"phanan/koel","fixedVersion":"9.7.1"}],"fix":{"url":"https://github.com/koel/koel/commit/5f6ce2cefd08f437a269236b677ad971517ccbb6","label":"koel/koel@5f6ce2c"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/50xxx/CVE-2026-50552.json"},{"type":"ADVISORY","url":"https://github.com/koel/koel/security/advisories/GHSA-jr4p-4xjh-fwvw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-50552"},{"type":"FIX","url":"https://github.com/koel/koel/commit/5f6ce2cefd08f437a269236b677ad971517ccbb6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:11.843171498Z"}}
