What is CVE-2026-118439?

The Limit Login Attempts Security plugin for WordPress, prior to version 3.4.2, is vulnerable to Server-Side Request Forgery (SSRF) attacks. This vulnerability arises from the plugin's failure to validate the destination of a server-side request constructed from a user-supplied setup value. As a result, users with administrator privileges may exploit this weakness to direct requests to arbitrary hosts, potentially exposing internal resources to unauthorized access. Website owners using this plugin should ensure they upgrade to the latest version to mitigate this risk.

Affected Version(s)

Limit Login Attempts Security 0 < 3.4.2

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.
