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
