Recommendation: Monitor — no exploitation signal at the moment.

WeKan versions prior to 8.19 contain an insecure direct object reference (IDOR) in the card comment creation API. The endpoint accepts an authorId from the request body, allowing an authenticated user to spoof the recorded comment author by supplying another user's identifier.
