Machine-written summary

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

AVideo (wwbn/avideo) versions up to and including 29.0 are affected. An unauthenticated attacker can inject extra calendar events into the .ics file served by the Scheduler plugin's downloadICS.php endpoint when that plugin is enabled, allowing forged meeting invitations for phishing. No fixed version is listed; disabling the Scheduler plugin removes the exposed endpoint.
