{"id":"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.","aliases":["GHSA-6qvr-wjmv-v8mm"],"modified":"2026-08-22T03:31:10.622948865Z","published":"2026-08-19T20:48:12.951Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54491.json","cna_assigner":"GitHub_M"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/koel/koel","events":[{"introduced":"0"},{"fixed":"5f6ce2cefd08f437a269236b677ad971517ccbb6"},{"fixed":"c264a3d52513a83b21e1cc3a20e895caea97fc4a"},{"fixed":"4292d9844faed1e0f78d62be388152fd981c7437"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"9.7.1"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v9.7.0","v9.6.0","v9.5.0","v9.4.1","v9.4.0","v9.3.6","v9.3.5","v9.3.4","v9.3.3","v9.3.2","v9.3.1","v9.3.0","v9.2.1","v9.2.0","v9.1.2","v9.1.1","v9.1.0","v9.0.0","v8.3.1","latest","v8.3.0","v8.2.0","v8.1.0","v8.0.0","v7.15.1","v7.15.0","v7.14.0","v7.13.0","v7.12.0","v7.11.0","v7.10.4","v7.10.3","v7.10.2","v7.10.1","v7.10.0","v7.9.0","v7.8.1","v7.8.0","v7.7.1","v7.7.0","v7.6.3","v7.6.2","v7.6.1","v7.6.0","v7.5.2","v7.5.1","v7.5.0","v7.4.2","v7.4.1","v7.4.0","v7.3.1","v7.3.0","v7.2.2","v7.2.1","v7.2.0","v7.1.0","v7.0.12","v7.0.11","v7.0.10","v7.0.9","v7.0.8","v7.0.7","v7.0.6","v7.0.5","v7.0.4","v7.0.3","v7.0.2","v7.0.1","v7.0.0","v6.12.1","v6.12.0","v6.11.5","v6.11.4","v6.11.3","v6.11.2","v6.11.1","v6.11.0","v6.10.0","v6.9.0","v6.8.5","v6.8.4","v6.8.3","v6.8.2","v6.8.1","v6.8.0","v6.7.5","v6.7.3","v6.7.2","v6.7.1","v6.7.0","v6.6.0","v6.5.3","v6.5.2","v6.5.1","v6.5.0","v6.4.3","v6.4.2","v6.4.1","v6.4.0","v6.3.0","v6.2.2","v6.2.1","v6.2.0","v6.1.0","v6.0.6","v6.0.5","v6.0.4","v6.0.3","v6.0.2","v6.0.1","v6.0.0","v5.1.14","v5.1.13","v5.1.12","v5.1.11","v5.1.10","v5.1.9","v5.1.8","v5.1.7","v5.1.6","v5.1.5","v5.1.4","v5.1.3","v5.1.2","v5.1.1","v5.1.0","v5.0.2","v5.0.1","v5.0.0","v4.4.0","v4.3.1","v4.3.0","v4.2.2","v4.2.1","v4.2.0","v4.1.1","v4.1.0","v4.0.0","v3.7.2","v3.7.1","v3.7.0","v3.6.2","v3.6.1","v3.6.0","v3.5.5","v3.5.4","v3.5.3","v3.5.2","v3.5.1","v3.5.0","v3.4.0","v3.3.1","v3.3.0","v3.2.0","v3.1.1","v3.1.0","v3.0.1","v3.0.0","v2.2.0","v2.1.0","v2.0.2","v2.0.1","v2.0.0","1.0.0-beta"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-54491.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N"}]}
