## Affected

- CapSoftware Cap: through 0.3.1

## Description

Cap v0.3.1 contains a broken access control vulnerability in the POST /api/video/comment endpoint that allows authenticated users to post comments on any private video without permission by supplying an arbitrary videoId in the request body. Attackers can inject comments into private video recordings belonging to other users, trigger comment notification emails to the video owner, and enumerate valid video IDs through response differences.
