What is CVE-2025-15691?

The WPFunnels plugin for WordPress prior to version 3.13.0 has a vulnerability that permits unauthenticated attackers to create user accounts without verifying if user registration is enabled. This flaw stems from the plugin's reliance on request-supplied values, which compromises site security by allowing account creation even when registration is disabled. The issue is partially addressed, having been noted as an incomplete fix for an earlier vulnerability, indicating ongoing risks associated with the registration paths.

Affected Version(s)

WPFunnels 3.6.3 < 3.13.0
