Path Traversal in Content Egg WordPress Plugin

Publication date: 2026-08-05

Last updated on: 2026-08-05

Assigner: Wordfence

Description
The Content Egg – Affiliate Product Importer & Price Comparison plugin for WordPress is vulnerable to Arbitrary File Deletion via Path Traversal in versions up to and including 11.3.0. This is due to insufficient validation of the 'img_file' field within the cegg_data post metadata: the value passes only through wp_strip_all_tags() (which does not strip path traversal sequences), is stored directly in post meta, and is later concatenated without normalization into a filesystem path in getFullImgPath() before being passed to PHP's unlink(). This makes it possible for authenticated attackers, with author-level access and above, to delete arbitrary files on the affected site's server which may make remote code execution possible.

Executive Summary

This vulnerability is an Arbitrary File Deletion issue in the Content Egg WordPress plugin. It allows authenticated attackers with author-level access or higher to delete arbitrary files on the server by exploiting path traversal through the 'img_file' field. The flaw occurs because user input is not properly sanitized before being used in filesystem operations.

Detection Guidance

Check WordPress sites using the Content Egg plugin for versions up to 11.3.0. Look for unauthorized file deletions in server logs. Inspect post meta data for suspicious 'cegg_data' entries with path traversal sequences in the 'img_file' field.

Impact Analysis

This vulnerability can lead to complete site compromise. Attackers could delete critical files, including WordPress core files, plugins, or themes, potentially causing site outages. In severe cases, this could enable remote code execution if attackers delete key files and replace them with malicious ones.

Compliance Impact

This vulnerability could lead to non-compliance with GDPR or HIPAA if it results in unauthorized data deletion or system compromise. GDPR requires data integrity and availability protections, while HIPAA mandates safeguards against unauthorized access or destruction of protected health information. A successful exploit could violate these requirements.

Mitigation Strategies

Immediately update the Content Egg plugin to the latest version. Remove author-level access for untrusted users. Monitor file system changes and server logs for suspicious activity. Consider disabling the plugin if not essential.
