Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
AVideo (Packagist package wwbn/avideo) versions prior to 22.0 are vulnerable to authenticated server-side request forgery through the downloadURL parameter in the aVideoEncoder.json.php endpoint, which fetches the supplied resource without adequate validation or an allow-list. An attacker with a user account can make the server send requests to arbitrary URLs, including internal network endpoints, and may retrieve sensitive data from them. The issue is fixed in version 22.0, and users should upgrade to that version.
