Original Issue Date:November 04, 2025

Severity Rating: CRITICAL

Software Affected

  • WordPress Plugin GutenKit versions 2.1.0 and prior
  • WordPress Plugin Hunk Companion versions 1.8.5 and prior

Overview

Multiple vulnerabilities have been reported in Hunk Companion and GutenKit plugin for WordPress which could allow an unauthenticated attacker to execute arbitrary code on the targeted system.

Target Audience:
Users of affected WordPress Plugins.

Risk Assessment:
High risk of unauthorised access.

Impact Assessment:
Potential for arbitrary code execution.

Description

Hunk Companion and GutenKit are WordPress plugins commonly used to enhance website design and page-building functionality within WordPress.

The vulnerability in the GutenKit plugin exists because its REST API endpoint lacks proper validation, allowing unauthenticated arbitrary file upload via /wp-json/gutenkit/v1/install-active-plugin. The vulnerability in the Hunk Companion plugin is due to a missing capability/authorization check on the /wp-json/hc/v1/themehunk-import REST.

Successful exploitation of these vulnerabilities could allow an unauthenticated attacker to execute arbitrary code on the targeted system.

Note: These vulnerabilities are being exploited in the wild.
