CVE-2026-12081

MEDIUM 5 PoC AVAILABLE

Published 2026-07-13 · Last modified 2026-07-13

The Database for Contact Form 7, WPforms, Elementor forms WordPress plugin before 1.5.2 does not restrict the PHP classes allowed when unserializing an attacker-supplied form-field value, allowing unauthenticated users to inject arbitrary PHP objects that are instantiated when an administrator views the stored entry. This is an incomplete fix of CVE-2025-7384 and CVE-2026-2599, whose deserialization paths were hardened while the entry-editor file-field path was missed.
