What is CVE-2026-14939?

The Visualizer plugin for WordPress before version 4.0.6 is susceptible to a Server-Side Request Forgery (SSRF) vulnerability. This weakness occurs because the plugin does not adequately limit user-supplied URLs to safe ranges before fetching them on the server side. This oversight permits users with Contributor-level access or higher to execute SSRF attacks against local instance-metadata endpoints. The responses retrieved through this exploit are directly returned, making it possible for attackers to access sensitive cloud instance metadata, including IAM credentials, on cloud-hosted environments.

Affected Version(s)

Visualizer 0 < 4.0.6

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.
