CVE-2022-0574Network attack vector

Unauthorized comments via missing publication-state check

Published May 16, 2022 · Updated Aug 2, 2024

Incorrect authorization in Publify before 9.2.8 allows remote attackers to post comments on draft or scheduled articles. Article#comments_closed? checks comment settings and the feedback window but omits published?, so the comment controller accepts and saves a comment for unpublished content. No account or user interaction is required, but exploitation requires an unpublished article identifier and alters that article's comment data without exposing its body.
