{"id":"CVE-2026-50552","state":"PUBLISHED","title":"Koel: Server-Side Request Forgery (SSRF) in radio station creation due to missing validation bail","description":"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.","publishedAt":"2026-06-12T18:51:46.028Z","updatedAt":"2026-06-15T15:25:23.537Z","severity":{"score":6.3,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L","source":"GitHub_M"},"assigner":"GitHub_M","products":["koel koel"],"affected":[{"vendor":"koel","product":"koel","versions":[{"version":"< 9.7.1","status":"affected"}]}],"references":["https://github.com/koel/koel/security/advisories/GHSA-jr4p-4xjh-fwvw","https://github.com/koel/koel/commit/5f6ce2cefd08f437a269236b677ad971517ccbb6"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:12:16.098Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/50xxx/CVE-2026-50552.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-50552","state":"PUBLISHED","datePublished":"2026-06-12T18:51:46.028Z","dateUpdated":"2026-06-15T15:25:23.537Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-06-04T20:37:18.654Z"},"containers":{"cna":{"title":"Koel: Server-Side Request Forgery (SSRF) in radio station creation due to missing validation bail","descriptions":[{"lang":"en","value":"Koel is a free, open-source music streaming solution.
