{"apiVersion":"1.0","identifier":"CVE-2026-54491","description":"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.","publishedAt":"2026-08-19T21:16:57","lastModifiedAt":"2026-08-20T20:17:34","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-54491","cvssScore":7.1,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N","epssProbability":0.00241,"riskScore":0.73,"affectedProduct":"Koel","affectedVersions":"<9.7.1","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-54491","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-54491","en":"https://www.redsauce.net/en/cves/CVE-2026-54491","fr":"https://www.redsauce.net/fr/cves/CVE-2026-54491","pt":"https://www.redsauce.net/pt/cves/CVE-2026-54491","de":"https://www.redsauce.net/de/cves/CVE-2026-54491","sk":"https://www.redsauce.net/sk/cves/CVE-2026-54491","el":"https://www.redsauce.net/el/cves/CVE-2026-54491"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-54491"}}
