Credential disclosure via user-controlled restream owner ID
Published Apr 21, 2026 · Updated Apr 21, 2026
IDOR in AVideo 29.0 and earlier allows remote authenticated users with streaming permission to read other users' restream secrets. The list.json.php handler honors a supplied users_id before applying the non-admin override, then passes that ID to getAllFromUser and returns every matching column. An account with streaming permission can enumerate sequential user IDs and obtain stream keys and OAuth access and refresh tokens, without reported write or service-interruption capabilities.
