Directory Traversal in WCPOS WooCommerce POS Plugin

Publication date: 2026-07-23

Last updated on: 2026-07-23

Assigner: Wordfence

Description
The WCPOS – Point of Sale (POS) plugin for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in all versions up to, and including, 1.9.8 via the 'type' parameter parameter. This makes it possible for authenticated attackers, with shop manager-level access and above, to read the contents of arbitrary files on the server, which can contain sensitive information. Successful exploitation requires supplying context=edit in the request, which bypasses the content-stripping logic in prepare_item_for_response() and returns the traversed file verbatim in the REST API response.

Executive Summary

This vulnerability is a Directory Traversal issue in the WCPOS – Point of Sale (POS) plugin for WooCommerce on WordPress. It affects versions up to and including 1.9.8. The flaw exists in the 'type' parameter and allows authenticated attackers with shop manager-level access or higher to read arbitrary files on the server by exploiting a bypass in the content-stripping logic of the REST API response.

Detection Guidance

To detect this vulnerability, check for unusual file access patterns or requests containing the 'type' parameter in WooCommerce REST API calls. Monitor logs for requests with 'context=edit' that return unexpected file contents. Use tools like grep to search for suspicious API calls in access logs.

Impact Analysis

An attacker could exploit this to access sensitive files on your server, potentially exposing confidential data such as configuration files, user credentials, or other critical information. This could lead to further attacks, data breaches, or unauthorized system access if combined with other vulnerabilities.

Compliance Impact

This vulnerability could lead to unauthorized access to sensitive data, violating compliance requirements under GDPR (data protection) and HIPAA (health information privacy). Organizations may face legal penalties, reputational damage, and loss of trust if such breaches occur due to inadequate security measures.

Mitigation Strategies

Immediately update the WCPOS plugin to the latest version if available. If not, disable the plugin until a patch is released. Restrict shop manager-level access to only necessary users. Monitor for unauthorized file access attempts and review server logs for suspicious activity.
