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 use the Subsonic-compatible podcast channel creation route to supply a private or internal URL, which makes the server fetch it and allows server-side request forgery to internal destinations that the main web API blocks. Upgrade to Koel 9.7.0 or later.
