What is CVE-2026-79631?

The WPFunnels plugin for WordPress prior to version 3.13.0 features an access control oversight, permitting unauthenticated users to download sensitive log files stored in a predictable location within the public uploads directory. This issue arises when logging is enabled, potentially exposing customer order details and opt-in form submissions to unauthorized access. Users of WPFunnels should update to version 3.13.0 or later to mitigate this risk.

Affected Version(s)

WPFunnels 2.6.0 < 3.13.0

Exploit Proof of Concept (PoC)
