FKIE_CVE-2026-13609

Vulnerability from fkie_nvd - Published: 2026-07-31 07:16 - Updated: 2026-08-26 16:31
Severity
8.8 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
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.
