{"id":"CVE-2026-54491","aliases":["GHSA-6qvr-wjmv-v8mm"],"url":"https://o3.security/vulnerability/CVE-2026-54491","summary":"Koel: Incomplete fix for CVE-2026-47260 — systemic SSRF in podcast & radio fetch paths","details":"Koel is a free, open-source music streaming solution. Prior to 9.7.1, outbound podcast and radio fetch paths perform a point-in-time App\\Helpers\\Network::isPublicHost() or isSafeUrl() check without pinning the validated address, and most paths lack redirect-hop validation and do not revalidate every redirect target. PhanAn\\Poddle\\Poddle::fromUrl(), PodcastService::getStreamableUrl(), PodcastService::isPodcastObsolete(), App\\Rules\\HasAudioContentType, and App\\Rules\\SafeUrl can therefore follow an attacker-controlled redirect to an internal address or connect after DNS rebinding changes a public resolution to a private one. These paths are reachable through podcast and radio APIs, including createPodcastChannel, createInternetRadioStation, refreshPodcasts, apiResource podcasts, and radio/stations, allowing an authenticated user to request internal services or cloud metadata and potentially receive parsed or streamed response content. This issue is fixed in version 9.7.1.","published":"2026-08-19T20:48:12.951Z","modified":"2026-08-22T03:31:10.622948865Z","cvss":{"score":7.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"},"epss":{"score":0.00241,"percentile":0.15123,"asOf":"2026-09-07"},"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":"WEB","url":"https://github.com/koel/koel/releases/tag/v9.7.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54491.json"},{"type":"ADVISORY","url":"https://github.com/koel/koel/security/advisories/GHSA-6qvr-wjmv-v8mm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54491"},{"type":"FIX","url":"https://github.com/koel/koel/commit/5f6ce2cefd08f437a269236b677ad971517ccbb6"},{"type":"FIX","url":"https://github.com/koel/koel/commit/c264a3d52513a83b21e1cc3a20e895caea97fc4a"},{"type":"FIX","url":"https://github.com/koel/koel/pull/2546"},{"type":"FIX","url":"https://github.com/koel/koel/pull/2549"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-22T03:31:10.622948865Z"}}
