What is CVE-2026-1165?

The Popup Box plugin for WordPress is susceptible to Cross-Site Request Forgery (CSRF) due to an issue in its nonce verification process within the 'publish_unpublish_popupbox' function. This vulnerability allows attackers to alter the publication status of popups by tricking an administrator into executing a forged request, bypassing security mechanisms. Affected versions include all versions up to 6.1.1. Proper nonce verification is essential to mitigate this risk and secure web applications against unauthorized actions.
