cvss: 8.8; version 3.1, CNA

epss: 0.6%; EPSS 0.6% chance of exploitation in 30 days, percentile 50%
public exploits: 0; none known

The FreeMind WP Browser plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including 1.2. This is due to missing nonce protection on the FreemindOptions() function found in the ~/freemind-wp-browser.php file. This makes it possible for unauthenticated attackers to inject malicious web scripts into the page, granted they can trick a site's administrator into performing an action such as clicking on a link.

Exploit prediction

0.64% chance of exploitation in the next 30 days, higher than 50% of all scored CVEs (FIRST EPSS, 2026-11-08).
