Vulnerability Overview

The WP Compress – Image Optimizer [All-In-One] plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 6.10.33 via the css parameter. This makes it possible for unauthenticated attackers to read the contents of arbitrary files on the server, which can contain sensitive information.

Technical Analysis

REMEDIATION: Update to version 6.10.34, or a newer patched version --- IDENTIFIER: CWE-24 (Path Traversal: '../filedir') The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize ../ sequences that can resolve to a location that is outside of that directory.
