Name of the Vulnerable Software and Affected Versions Blinko versions prior to 1.8.4

Specifically, the /api/v1/comment/create endpoint permits attackers to post comments on any note, including private ones, without proper authorization. The /api/v1/comment/list endpoint also suffers from this problem, allowing unauthorized viewing of comments on all notes. The vulnerable parameters are not specified.
