AnalysisAIv1 – Aug 24, 2026

Unauthenticated arbitrary file deletion in WooCommerce File Approval plugin (versions through 10.7) allows any remote attacker to delete arbitrary files on the underlying server without credentials or user interaction. The path traversal root cause (CWE-22) enables attackers to escape the plugin's intended file handling scope, with the CVSS S:C scope-change indicator confirming that files outside the plugin's own directory — including WordPress core files, configuration files, or OS-level files accessible to the web server process — can be targeted. No public exploit code or active exploitation (CISA KEV) has been identified at time of analysis, though the zero-complexity, unauthenticated attack surface makes this a high-priority remediation target for any site running the affected plugin.

DescriptionCVE.org

Unauthenticated Arbitrary File Deletion in WooCommerce File Approval <= 10.7 versions.

Executive ViewAI

Why It Matters

The WooCommerce File Approval plugin versions 10.7 and earlier contain a critical unauthenticated arbitrary file deletion vulnerability affecting any WordPress site using this plugin. Attackers can delete critical website files including WordPress core, configuration files, and data without requiring credentials, potentially causing site downtime and data loss. Organizations must treat this as an immediate remediation priority for all affected deployments.

Recommended Action

Within 24 hours: Scan all WordPress instances for WooCommerce File Approval plugin versions 10.7 and earlier; immediately disable and remove the plugin from production, staging, and development environments. Implement WAF rules to deny POST requests to the plugin's file handling endpoints. Within 7 days: Audit affected server filesystems for unauthorized deletions; configure enhanced logging and alerts on file deletion attempts targeting web-accessible directories; review backup integrity and restoration procedures. Within 30 days: Deploy a replacement file management plugin with equivalent functionality, or monitor vendor advisory channels for patch release information. Maintain an inventory of all previously affected systems with remediation completion dates.

Business Impact: High
Compensating Controls

Disable and remove the vulnerable plugin (primary mitigation). Implement strict file permissions restricting web server process write access to essential directories only. Deploy Web Application Firewall rules blocking requests to /wp-content/plugins/file-approval/ endpoints. Enable file integrity monitoring on critical WordPress directories. Maintain current, tested backups stored separately from the live environment with validated restore procedures. Implement access logging and alerting for file deletion operations at the OS level.

Attack Technique

Path traversal exploits occur when applications use user-controlled input to construct file system paths without proper validation.
