CVE-2025-4202
MediumCVSS 4.3Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
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.
Risk Assessment
A low-privileged user can modify data in collaborations they should not have access to, potentially leading to unauthorized content injection or disruption of team workflows.
Recommendation
Update the Multicollab plugin to a version higher than 5.2 if available. Otherwise, consider restricting user privileges or disabling the plugin.
