Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Packagist package wwbn/avideo versions up to and including 29.0 are affected. A same-domain check in the SSRF protection function compares only the hostname and ignores the port, so an authenticated user with upload permission (or a holder of a valid video hash token) can make the server fetch arbitrary local ports on the same host. The response is saved to a web-accessible path, letting the attacker read internal service responses. No fixed version is listed, so check for a newer release or apply the recommended change to compare both hostname and port in the same-domain check.
