CVE-2026-91015 · Severity: medium · CVSS 5.3 · Published 2026-09-17

The Master Addons for Elementor WordPress plugin contains a flaw in its Popup Builder feature that allows unauthenticated visitors to permanently disable popups on websites. The vulnerability bypasses authorization checks by relying only on a publicly visible security token, enabling attackers to disrupt critical popup functionality used for marketing, notifications, and customer engagement.

## Technical details

The plugin fails to enforce authorization checks on the AJAX action jltma_popup_disable_expired, which deactivates Popup Builder popups. The vulnerability relies solely on a nonce that is publicly output to all visitors, making the nonce predictable and useless as a security control. An unauthenticated attacker can craft an AJAX request to permanently disable any popup on the site. This is a broken access control vulnerability (CWE-862) that was patched in version 3.1.9.
