## Affected

- WWBN AVideo: through 29.0

## Description

WWBN AVideo fails to properly validate access controls on the public channel page, allowing unauthenticated visitors to view unlisted and group-restricted videos through hardcoded visibility flags and an undefined property. Attackers can access the channel endpoint to retrieve sensitive video content that should be hidden, including full URLs to unlisted videos and thumbnails of member-only content, regardless of the operator's hidePrivateVideos setting.
