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, has a cross-site request forgery flaw in objects/userSavePhoto.php, which lets a page on another site overwrite a logged-in user's profile photo with arbitrary bytes. An attacker needs only to lure a logged-in user to a malicious page, and the request is sent with the victim's session cookie. No fixed version is listed. The source recommends adding a same-origin check and content validation to the handler, and it also warns that userSaveBackground.php has the same weakness.
