Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
