CVE-2026-25397: 
WordPress vulnerability analysis and mitigation

CVE-2026-25397 is a path traversal vulnerability (specifically the .../...// variant) in the Snowray Software "File Uploader for WooCommerce" WordPress plugin. It affects all versions of the plugin from the initial release through version 1.0.4. The vulnerability was published on March 25, 2026, and was assigned by Patchstack. It carries a CVSS v3.1 base score of 7.5 (High) (Feedly, Patchstack).

The vulnerability is classified under CWE-35 (Path Traversal: .../...//) and CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). The flaw arises from insufficient sanitization of user-supplied file path input within the plugin's file upload handling logic, allowing an attacker to craft a request using the .../...// traversal sequence to bypass directory restrictions. No authentication or user interaction is required, and the attack is conducted entirely over the network with low complexity (Feedly, Patchstack).

Successful exploitation allows an unauthenticated remote attacker to read arbitrary files outside the intended upload directory on the web server, resulting in a high confidentiality impact. Sensitive files such as WordPress configuration files (wp-config.php) containing database credentials, secret keys, and other sensitive data could be exposed. There is no direct integrity or availability impact based on the current CVSS assessment (Feedly).

No public proof-of-concept exploit code or evidence of in-the-wild exploitation has been reported at this time. The EPSS score is approximately 0.026%, indicating a low probability of exploitation in the near term. The vulnerability is not currently listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. No threat actor attribution has been identified (Feedly).

1. Reconnaissance: Identify WordPress sites running the "File Uploader for WooCommerce" plugin (version ≤ 1.0.4) using tools like WPScan, Shodan, or by checking publicly accessible plugin metadata at https://target.com/wp-content/plugins/file-uploader-for-woocommerce/readme.txt.
2. Identify vulnerable endpoint: Locate the plugin's file upload or file retrieval endpoint, typically exposed via a WordPress AJAX action or a direct PHP script within the plugin directory.
3. Craft traversal payload: Construct an HTTP request with a path traversal sequence using the .../...// pattern in the filename or path parameter (e.g., filename=.../...//wp-config.php) to bypass directory restriction checks.
4. Send the request: Submit the crafted request to the target endpoint without any authentication credentials.
5. Retrieve sensitive files: If successful, the server returns the contents of the targeted file (e.g., wp-config.php), exposing database credentials, authentication keys, and other sensitive configuration data (Feedly, Patchstack).

• Network: Unusual HTTP GET or POST requests to plugin endpoints containing .../...// or URL-encoded variants (e.g., %2e%2e%2e%2f%2e%2e%2e%2f%2f) in path or filename parameters; requests originating from unexpected IP addresses targeting the plugin's upload/download endpoints.
• Logs: Web server access logs (Apache/Nginx) showing requests to /wp-content/plugins/file-uploader-for-woocommerce/ with traversal sequences in query strings or POST bodies; HTTP 200 responses to requests containing wp-config.php or other sensitive filenames.
• File System: No direct file system artifacts expected for read-only path traversal; however, monitor for unexpected access to wp-config.php or other sensitive files via file integrity monitoring tools.

Users should update the "File Uploader for WooCommerce" plugin to a version beyond 1.0.4 if a patched release is available from the plugin vendor (Snowray Software) or the WordPress plugin repository. If no patched version is yet available, the recommended workaround is to deactivate and remove the plugin until a fix is released. Additionally, implementing a Web Application Firewall (WAF) rule to block requests containing path traversal sequences (.../...//) targeting the plugin's endpoints can provide interim protection (Patchstack, Feedly).

Wordfence included this vulnerability in their weekly WordPress vulnerability report covering March 23–29, 2026, highlighting it as part of a broader set of plugin vulnerabilities disclosed that week (Wordfence). No significant additional vendor statements, researcher commentary, or notable social media discussion has been identified beyond standard vulnerability database listings.
