CVE-2026-8423
The JaviBola Custom Theme Test plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.5.
Does this matter?
Lower severity and a low EPSS score (0.18%). Track it; it rarely justifies an emergency change on its own.
Description
The JaviBola Custom Theme Test plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.0.5. This is due to missing or incorrect nonce validation on the options page. This makes it possible for unauthenticated attackers to change the site's active theme by modifying the jbct_theme option via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
