What is CVE-2026-12081?

A vulnerability exists in multiple WordPress form plugins, allowing unauthenticated users to inject arbitrary PHP objects through unserialized form-field values. When an administrator views the stored entry, these injected objects can be instantiated, potentially leading to unauthorized actions or data exposure. This issue is a result of an incomplete fix for previous vulnerabilities where certain deserialization paths were left unaddressed.

Affected Version(s)

Database for Contact Form 7, WPforms, Elementor forms 0 < 1.5.2

Exploit Proof of Concept (PoC)
