## What is CVE-2026-3328?

CVE-2026-3328 is a high-severity unsafe deserialization vulnerability in shabti Frontend Admin by DynamiApps, published on 26 Mar 2026. An attacker needs administrator access to exploit it, with no action from the victim.

### Official description

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.

Weakness: CWE-502 (Deserialization of Untrusted Data)
