Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Koel versions before 9.7.0 are affected. An authenticated user can create or update an internet radio station through the Subsonic-compatible endpoints with a private or internal URL, which bypasses the URL checks on the regular web API. When the station is streamed, the server fetches that URL and returns the response body to the user, allowing reads of internal HTTP services. Upgrade to Koel 9.7.0 or later.
