- Severity: CVSS 4.3 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial

- Published: 2026-01-31 · Updated: 2026-04-08

## Affected

- ays-pro Popup Box – Create Countdown, Coupon, Video, Contact Form Popups: through 6.1.1

## 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.
