CERT-In Vulnerability Note CIVN-2025-0332
Command Injection Vulnerability in W3 Total Cache WordPress Plugin

Original Issue Date:November 21, 2025

Severity Rating: CRITICAL

Software Affected

  • W3 Total Cache WordPress plugin versions prior to 2.8.13

Overview

A critical vulnerability has been reported in the W3 Total Cache WordPress plugin, which could allow an unauthenticated, remote attacker to execute arbitrary PHP code on the targeted system.

Target Audience:
Administrators and organisations using WordPress websites with the W3 Total Cache plugin installed.

Risk Assessment:
High likelihood of exploitation due to unauthenticated access through public comment submission.

Impact Assessment:
Potential data theft, malware deployment, or complete website takeover.

Description

W3 Total Cache is a widely used WordPress plugin intended to improve website performance through caching, minification, and CDN integration.

A command injection vulnerability exists in the plugin due to improper input sanitisation in the parse_dynamic_mfunc (also referenced as _parse_dynamic_mfunc) function. The flaw allows user-supplied input¿especially via publicly accessible comment forms¿to be processed as executable PHP code.

An unauthenticated attacker can deliver a specially crafted comment containing malicious payloads. When processed by the vulnerable function, these payloads result in arbitrary PHP command execution on the server.

Successful exploitation of this vulnerability could allow an unauthenticated, remote attacker to execute arbitrary PHP code on the targeted system.
