FKIE_CVE-2026-3328

Vulnerability from fkie_nvd - Published: 2026-03-26 04:17 - Updated: 2026-04-24 16:35
Severity ?
7.2 (High) - CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H
Summary
The Frontend Admin by DynamiApps plugin for WordPress is vulnerable to PHP Object Injection via deserialization of the 'post_content' of admin_form posts in all versions up to, and including, 3.28.31. This is due to the use of WordPress's `maybe_unserialize()` function without class restrictions on user-controllable content stored in admin_form post content. This makes it possible for authenticated attackers, with Editor-level access and above, to inject a PHP Object. The additional presence of a POP chain allows attackers to achieve remote code execution.
