Prior to version 1.8.4, the /api/v1/comment/create endpoint has an unauthorized access vulnerability, allowing attackers to post comments on any note (including private notes) without authorization, even if the note has not been publicly shared. The /api/v1/comment/list endpoint has the same issue, allowing unauthorized viewing of comments on all notes.
