CVE-2026-1165 – Popup Box

CVE ID : CVE-2026-1165

Published : Jan. 31, 2026, 2:22 p.m. | 51 minutes ago

Description : The Popup Box plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.1.1. This is due to a flawed nonce implementation in the ‘publish_unpublish_popupbox’ function that verifies a self-created nonce rather than one submitted in the request. This makes it possible for unauthenticated attackers to change the publish status of popups via a forged request, granted they can trick a site administrator into performing an action such as clicking a link.

Severity: 0.0 | NA
