CVE-2025-4202 Medium · 4.3 CWE-862 May 16, 2026

Multicollab: Content Team Collaboration and Editorial Workflow <= 5.2 - Missing Authorization to Authenticated (Subscriber+) Collaboration Comment

The Multicollab: Content Team Collaboration and Editorial Workflow plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'cf_add_comment' function in all versions up to, and including, 5.2. This makes it possible for authenticated attackers, with Subscriber-level access and above, to add comments to arbitrary collaborations.
