What is CVE-2026-121873?

The Contact Form 7 plugin for WordPress, prior to version 3.2.16, contains a vulnerability that allows unauthenticated users to create verified personal data erasure or export requests. This occurs due to a lack of verification for the ownership of email addresses submitted through its data request form action, marking requests as confirmed by default and potentially exposing sensitive user information.

Affected Version(s)

Redirection for Contact Form 7 2.6.0 < 3.2.16

Exploit Proof of Concept (PoC)
