Executive Summary

Craft CMS versions before 5.10.11 have a flaw in the assets/move-asset endpoint. When the force=1 parameter is used, authenticated users without proper permissions can move their own assets into other users' folders. This can force deletion of existing files and replace them with unauthorized content, leading to data integrity issues.

Detection Guidance

Check Craft CMS version with: composer show craftcms/cms. If version is below 5.10.11, the system is vulnerable. Review server logs for unusual asset/move-asset endpoint activity with force=1 parameter.

Impact Analysis

An attacker could delete or replace critical files in your Craft CMS installation, such as images, documents, or other assets. This may disrupt services, cause data loss, or allow unauthorized content to be displayed to users. The impact depends on which assets are affected.

Compliance Impact

This vulnerability could lead to unauthorized data modification or deletion, violating integrity requirements in GDPR and HIPAA. If sensitive assets are altered or lost, it may result in non-compliance with data protection regulations, potentially leading to legal or financial penalties.

Mitigation Strategies

Upgrade Craft CMS to version 5.10.11 or later immediately. Temporarily restrict access to the assets/move-asset endpoint if immediate upgrade is not possible.
