CVE-2026-50552 Details
Description
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.
A Server-Side Request Forgery (SSRF) vulnerability has been identified in Koel, a music streaming application, in versions prior to 9.7.1. The issue arises in the radio station creation endpoint (POST /api/radio/stations), where the URL validation rules allow for private or reserved addresses to be accessed. This vulnerability can be exploited by authenticated, non-admin users to make HEAD or GET requests to internal hosts, potentially leading to unauthorized access or manipulation of internal resources.
Users can update to Koel version 9.7.1 or later, where this vulnerability has been patched.
