## Affected

- Chocobozzz/PeerTube: fixed in 7.1.1

## Description

This vulnerability allows any attacker to add playlists to a different user’s channel using the ActivityPub protocol. The vulnerable code sets the owner of the new playlist to be the user who performed the request, and then sets the associated channel to the channel ID supplied by the request, without checking if it belongs to the user.

## What to do
