CVE-2022-40206Network attack vector

Subscriber-level post privacy change via IDOR

Published Nov 8, 2022 · Updated Apr 28, 2026

Authentication bypass in wpForo Forum <= 2.0.5 allows remote authenticated users to mark any forum post private or public. The published records do not identify the vulnerable endpoint, parameter, function, or direct-object check, so the precise untrusted input operation remains undisclosed. Subscriber-level or higher WordPress access is required, and the demonstrated consequence is unauthorized alteration of forum-post visibility rather than arbitrary code execution.
