Cap's GET /api/video/ai endpoint fails to validate user ownership or membership before returning private video AI metadata including titles, summaries, and chapters. Authenticated attackers can supply arbitrary video IDs to read sensitive AI-generated content and trigger unauthorized AI generation that consumes the video owner's credits without consent.
