Technical details
The Frontend Admin by DynamiApps plugin (acf-frontend-form-element) fails to properly sanitize form field inputs. Specifically, the plugin decodes HTML entities after the initial sanitization process, which effectively restores and 'activates' neutralized HTML tags. An unauthenticated attacker can submit a double-encoded payload that bypasses filters, resulting in the payload being stored as a live tag. When this stored value is later rendered on front-end display surfaces without escaping, the malicious script executes in the context of the viewing user's session. This vulnerability is fixed in version 3.29.9.
