What is CVE-2026-11571?

The Everest Forms plugin for WordPress, prior to version 3.5.0, fails to properly manage temporary CSV files created during email notification processes. This oversight leaves the files accessible in the public uploads directory. As a result, unauthenticated attackers can exploit this vulnerability to retrieve sensitive information from form submissions using predictable and enumerable filenames, posing significant privacy risks to users.

Affected Version(s)

Everest Forms 0 < 3.5.0

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
