    CVE-2026-50552 (GCVE-0-2026-50552)

    Vulnerability from cvelistv5 – Published: 2026-06-12 18:51 – Updated: 2026-06-15 15:25

    Title
    Koel: Server-Side Request Forgery (SSRF) in radio station creation due to missing validation bail
    Summary
    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.

    Title
    Koel Vulnerable to SSRF via Podcast Episode Enclosure URLs
    Summary
    Koel is a free, open-source music streaming solution. Prior to version 9.3.5, Koel validates the podcast feed URL via the SafeUrl rule (DNS resolution + public IP check), but the individual episode <enclosure url="..."> values extracted from the RSS XML are stored directly into the database without any SSRF validation. When a user plays an episode, the server downloads the full HTTP response from the unvalidated enclosure URL via Http::sink()->get() and streams it back to the user, enabling full-read SSRF against internal services. This issue has been patched in version 9.3.5.
