Technical details
The vulnerability is classified as broken access control (OWASP A1), allowing authenticated users with subscriber-level privileges to bypass authorization checks and access restricted resources. The affected plugin versions up to 1.0.9 fail to properly enforce access control rules on sensitive pages or actions. An attacker with a valid WordPress account (even at subscriber level) can exploit this by directly requesting protected endpoints or pages. The Patchstack advisory notes that this is unlikely to be actively exploited in the wild; however, no official patch was available as of the publication date (31 December 2025).
