CVE-2026-13609

Frontend Admin by DynamiApps < 3.29.9 - Unauthenticated Stored Cross-Site Scripting via Form Field

Published Jul 31, 2026 CVSS 3.1 · 8.8 High EPSS < 1% KEV · Not listed
Description
The Frontend Admin by DynamiApps WordPress plugin before 3.29.9 decodes HTML entities in a submitted form field value after sanitizing it, which restores HTML tags that the sanitizer had neutralized. A double-encoded payload submitted by an unauthenticated visitor is therefore stored as a live tag and later output without escaping on the Frontend Admin by DynamiApps WordPress plugin before 3.29.9's front-end display surfaces, resulting in stored cross-site scripting that executes in the browser of any user, including an administrator, who views a page displaying the submitted value.
