CVE-2026-91092

wpForo Forum <= 3.1.5 - Missing Authorization to Authenticated (Subscriber+) Guest Post Takeover via wpforo_post_edit Action / Forged comment_author_email Cookie

Description

The wpForo Forum plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.1.5. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to take over another guest author's forum post and modify its title, body, author name, and stored owner email address. This requires that guest posting and editing are enabled on the forum, and that the attacker knows the target guest author's email address.
