{"id":"CVE-2026-54492","summary":"Koel: Authenticated Blind SSRF via Subsonic Podcast Channel Creation","details":"Koel is a free, open-source music streaming solution. Prior to 9.7.0, the Subsonic-compatible createPodcastChannel.view route accepts an authenticated user's private URL because app/Http/Requests/Subsonic/CreatePodcastChannelRequest.php does not apply the SafeUrl validation used by the regular podcast API. app/Http/Controllers/Subsonic/CreatePodcastChannelController.php passes the URL to app/Services/Podcast/PodcastService.php, where PodcastService::addPodcast() and createParser() invoke Poddle::fromUrl() during channel creation, causing immediate server-side requests to loopback, Docker bridge, or RFC1918 HTTP destinations. The confirmed impact is blind internal request execution because generic response-body exfiltration was not demonstrated through this route. This issue is fixed in version 9.7.0.","aliases":["GHSA-w79m-f3jx-779v"],"modified":"2026-08-22T03:30:58.396861208Z","published":"2026-08-19T20:44:33.090Z","database_specific":{"cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54492.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/koel/koel/releases/tag/v9.7.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/54xxx/CVE-2026-54492.json"},{"type":"ADVISORY","url":"https://github.com/koel/koel/security/advisories/GHSA-w79m-f3jx-779v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-54492"},{"type":"FIX","url":"https://github.com/koel/koel/commit/1331f335342b405e60ffabdd60f1f398508f996f"},{"type":"FIX","url":"https://github.com/koel/koel/pull/2545"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/koel/koel","events":[{"introduced":"0"},{"fixed":"1331f335342b405e60ffabdd60f1f398508f996f"},{"fixed":"8ee1de0f5589ef34d3e3bbb9c9555a5de69eaf06"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"9.7.0"}]}}],"versions":["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-2026-54492.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:L/I:N/A:N"}]}
