Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-ccq9-r5cw-5hwq: The WWBN AVideo package (wwbn/avideo, Packagist) through version 29.0 reflects any arbitrary Origin header with Access-Control-Allow-Credentials set to true on its primary API endpoints. A attacker who gets a logged-in user to visit a malicious web page can read authenticated API responses, including personal data, livestream credentials and stream keys, and can send state-changing requests as that user. No fixed version is listed. The source gives no workaround.
