What is CVE-2026-13694?

The Bit Form WordPress plugin prior to version 3.1.0 is prone to a security issue where it fails to properly validate its workflow-trigger token after the associated transient expires. As a result, unauthenticated attackers can exploit this weakness to re-trigger form actions, including sending notification emails and other configured workflows. This flaw poses significant risks as it undermines the intended security measures, allowing unauthorized access to workflow functionality.

Affected Version(s)

Bit Form 0 < 3.1.0

Exploit Proof of Concept (PoC)
