CVE-2025-9631: Gyaku Autocatset

Medium severity, CVSS 4.3. EPSS: 0.2% chance of exploitation in the next 30 days.

The AutoCatSet plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.1.4. This is due to missing or incorrect nonce validation on the autocatset_ajax function. This makes it possible for unauthenticated attackers to trigger automatic recategorization of posts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
