6DescriptionCVE.org
The Master Addons for Elementor WordPress plugin before 3.1.9 does not perform an authorization check on the AJAX action that deactivates its Popup Builder popups, relying only on a nonce that is publicly output to every visitor, allowing unauthenticated attackers to permanently disable any popup on the site.
AnalysisAI
Unauthenticated remote attackers can disable any Popup Builder popup on WordPress sites running Master Addons for Elementor versions 3.0.0 through before 3.1.9, because the plugin's AJAX popup-deactivation action performs no authorization check and relies solely on a nonce that is exposed to every visitor. Publicly available exploit code exists, but the impact is deliberately narrow: only the integrity of the popup feature (CWE-862 missing authorization, CVSS 5.3 with I:L) is affected, there is no data disclosure or code execution, and an administrator can undo the change by re-enabling the popup. …

Vulnerability AssessmentAI
| Exploitation | No special conditions - remote unauthenticated exploitation against default configurations of Master Addons for Elementor versions 3.0.0 through before 3.1.9, requiring only that the plugin's Popup Builder feature is in use (i.e., the site has popups to disable). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This is a genuine but modest-impact issue. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade Master Addons for Elementor to version 3.1.9 or later; this is the vendor-released patch and the only complete fix, since it adds the missing authorization check to the AJAX popup-deactivation handler. … Detailed patch versions, workarounds, and compensating controls in full report. |
