Vulnerability Overview

The Crayon Syntax Highlighter Plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the crayon-theme-editor-save AJAX action in versions 2.0 - 2.6.10. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to overwrite theme files.

Technical Analysis

REMEDIATION: Update to version 2.7.0, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
