CVE-2025-14301: WordPress Plugin Path Traversal Flaw

CVE-2025-14301 Overview

The Integration Opvius AI for WooCommerce plugin for WordPress contains a critical Path Traversal vulnerability affecting all versions up to and including 1.3.0. This vulnerability exists in the process_table_bulk_actions() function, which processes user-supplied file paths without implementing authentication checks, nonce verification, or path validation. Unauthenticated remote attackers can exploit this flaw to delete or download arbitrary files on the server via the wsaw-log[] POST parameter.

Critical Impact

Unauthenticated attackers can delete critical WordPress files such as wp-config.php or read sensitive configuration files, potentially leading to complete site compromise, data theft, or denial of service.

Affected Products

• Integration Opvius AI for WooCommerce plugin versions ≤ 1.3.0
• WordPress installations with the vulnerable plugin installed
• WooCommerce sites utilizing the Opvius AI integration

Technical Details for CVE-2025-14301

Vulnerability Analysis

This Path Traversal vulnerability (CWE-22) allows unauthenticated attackers to manipulate file paths processed by the vulnerable plugin. The core issue lies in the process_table_bulk_actions() function within the class-module-logger-hook.php file, which accepts user-controlled input through the wsaw-log[] POST parameter without any security controls.

The function fails to implement three critical security measures: authentication checks to verify the user's identity, nonce verification to prevent CSRF attacks, and path validation to restrict file operations to intended directories. This combination of missing security controls creates a severe attack surface that allows attackers to traverse directories using sequences like ../ to access files outside the intended log directory.

Successful exploitation enables attackers to perform arbitrary file deletion, which can be weaponized to remove wp-config.php and trigger WordPress's installation wizard, allowing attackers to reconfigure the site. Additionally, attackers can download sensitive files containing database credentials, authentication keys, and other confidential configuration data.

Root Cause

The root cause of this vulnerability is the absence of input validation and access control mechanisms in the file handling functionality. The process_table_bulk_actions() function directly uses user-supplied file paths from the wsaw-log[] POST parameter without sanitizing directory traversal sequences or validating that the target files reside within an allowed directory. Furthermore, the endpoint lacks authentication requirements, allowing any remote attacker to invoke this dangerous functionality.

Attack Vector

The attack vector is network-based and requires no authentication or user interaction. An attacker can craft a malicious POST request containing path traversal sequences in the wsaw-log[] parameter to target arbitrary files on the server. The attack complexity is low as it only requires knowledge of the vulnerable endpoint and standard file system paths.

For example, an attacker could target wp-config.php by including path traversal sequences that navigate from the plugin's log directory to the WordPress root directory. Once critical files are deleted or sensitive configuration files are downloaded, the attacker gains significant control over the WordPress installation.

Technical details regarding the vulnerable code paths can be found in the WordPress Plugin Source Code and the Wordfence Vulnerability Report.

Detection Methods for CVE-2025-14301

Indicators of Compromise

• Unexpected POST requests to WordPress containing wsaw-log[] parameters with path traversal sequences (../)
• Missing or modified wp-config.php or other critical WordPress files
• Unexplained WordPress installation wizard appearing on established sites
• Web server logs showing suspicious POST requests targeting the Integration Opvius AI plugin endpoints
• Evidence of unauthorized file access or download attempts in server access logs

Detection Strategies

• Monitor web application firewall (WAF) logs for requests containing path traversal patterns such as ../, ..%2f, or similar encoded sequences
• Implement file integrity monitoring (FIM) to detect unauthorized modifications or deletions of critical WordPress files
• Deploy SIEM rules to alert on POST requests with wsaw-log[] parameters, especially those containing traversal characters
• Review WordPress plugin logs for unusual bulk action processing events

Monitoring Recommendations

• Enable verbose logging on web servers to capture full POST request parameters
• Configure intrusion detection systems to flag path traversal attack patterns
• Set up automated alerts for changes to critical files including wp-config.php, .htaccess, and core WordPress files
• Implement real-time monitoring of WordPress plugin activity using security plugins

How to Mitigate CVE-2025-14301

Immediate Actions Required

• Immediately disable or uninstall the Integration Opvius AI for WooCommerce plugin if running version 1.3.0 or earlier
• Review server logs for evidence of exploitation attempts targeting this vulnerability
• Verify the integrity of critical WordPress files, particularly wp-config.php
• Consider restoring affected files from known-good backups if compromise is suspected
• Implement a Web Application Firewall rule to block requests containing path traversal sequences in the wsaw-log[] parameter

Patch Information

As of the last NVD update on January 14, 2026, users should check for plugin updates that address this vulnerability. Monitor the official WordPress plugin repository and the Wordfence Vulnerability Report for patch availability information. Until a patched version is confirmed, the safest course of action is to deactivate and remove the vulnerable plugin from production WordPress installations.

Workarounds

• Deactivate the Integration Opvius AI for WooCommerce plugin until a security patch is available
• Implement WAF rules to block POST requests containing path traversal patterns targeting this plugin
• Restrict access to WordPress admin endpoints at the web server level using IP allowlisting
• Enable WordPress file change detection to alert on unauthorized modifications

# Apache .htaccess rule to block path traversal attempts
<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (\.\./|\.\.%2f) [NC,OR]
    RewriteCond %{REQUEST_BODY} (\.\./|\.\.%2f) [NC]
    RewriteRule .* - [F,L]
</IfModule>

# Nginx configuration to block path traversal
location ~ /wp-admin/ {
    if ($request_body ~* "(\.\./|\.\.%2f)") {
        return 403;
    }
