Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Koel (phanan/koel) versions before 9.7.1 are affected. An authenticated user, including a non-admin account, can supply a URL on an attacker-controlled host that redirects to an internal address, or use DNS rebinding, so the Koel server issues requests to internal or cloud-metadata endpoints (server-side request forgery). Upgrade to 9.7.1, which is the listed fixed version.
