Summary

The JCH Optimize WordPress plugin before version 5.0.1 does not properly restrict a directory path provided to one of its administrative image-browsing features to within the site. This allows high-privilege users, administrators on single-site and sub-site administrators on multisite, to enumerate directories and file names outside the web root.

Risk Assessment

The organization is at risk of disclosure of directory structure and file names outside the web root, potentially facilitating attacks and compromising system information confidentiality.

Update the JCH Optimize plugin to version 5.0.1 or later and restrict administrator privileges in multisite environments.
