What is CVE-2026-58447?

Invidious versions up to 2.20260626.0 are susceptible to a broken object level authorization vulnerability, enabling authenticated attackers to delete videos from any user's playlists by manipulating global video indices in the remove_video action of the playlist endpoint. This vulnerability lacks ownership validation, allowing attackers to leverage the public playlist JSON API to gain access to per-video index values and use them to delete videos from playlists they do not own, resulting in unauthorized deletion of user content.
