CVE-2026-49061 Overview
CVE-2026-49061 is an unauthenticated arbitrary file download vulnerability in the WPC Product Options for WooCommerce WordPress plugin. The flaw affects all versions up to and including 3.2.1. The vulnerability is classified under CWE-22 (Improper Limitation of a Pathname to a Restricted Directory). Remote attackers can exploit it over the network without authentication or user interaction. Successful exploitation allows attackers to download arbitrary files from the WordPress host, leading to disclosure of sensitive data such as wp-config.php, database credentials, and authentication secrets.
Critical Impact
Unauthenticated attackers can retrieve sensitive WordPress configuration files, including database credentials and authentication keys, directly from vulnerable WooCommerce stores.
Affected Products
- WPC Product Options for WooCommerce plugin versions <= 3.2.1
- WordPress sites running WooCommerce with the affected plugin installed
- Hosting environments exposing the WordPress instance to the network

Technical Details for CVE-2026-49061
Vulnerability Analysis
The vulnerability is a path traversal flaw that exposes a file download endpoint to unauthenticated users. The plugin fails to validate or sanitize user-supplied file path parameters before serving the requested file. Attackers craft HTTP requests containing traversal sequences such as ../ to escape the intended plugin directory and read arbitrary files on the server filesystem.
The impact focuses on confidentiality. Attackers cannot directly modify files or crash the service through this flaw, but the leaked information frequently enables follow-on attacks. Disclosure of wp-config.php exposes the WordPress AUTH_KEY, SECURE_AUTH_KEY, and database credentials, often enabling full site compromise.
The EPSS score is 0.373%, reflecting moderate near-term exploitation probability for an unauthenticated WordPress plugin flaw. WordPress plugin vulnerabilities of this class are routinely incorporated into automated mass-scanning tools shortly after disclosure.
Root Cause
The root cause is missing input validation on a file path parameter handled by a publicly accessible plugin endpoint. The download handler accepts a filename or path supplied by the requester and passes it to a file read operation without canonicalization or directory restriction. The endpoint also lacks authentication and capability checks, allowing any anonymous visitor to invoke it.
Attack Vector
The attack vector is network-based through standard HTTP or HTTPS requests to the WordPress site. An attacker sends a single crafted request to the vulnerable plugin endpoint with a traversal payload in the file parameter. No credentials, session cookies, or user interaction are required. The server responds with the contents of the requested file. Refer to the Patchstack Vulnerability Report for endpoint-specific details.
Detection Methods for CVE-2026-49061
Indicators of Compromise
- HTTP requests to plugin endpoints under /wp-content/plugins/wpc-product-options/ containing traversal sequences such as ../, ..%2f, or encoded variants
- Anonymous requests where the response body contains contents resembling wp-config.php, define('DB_PASSWORD'...), or PHP source code
- Outbound responses with Content-Type: application/octet-stream or Content-Disposition: attachment originating from the affected plugin path
- Spikes in GET requests to a single plugin handler from unfamiliar source IP addresses
Detection Strategies
- Inspect web server access logs for query strings containing file=, path=, or similar parameters combined with .. sequences
- Deploy web application firewall (WAF) rules to flag path traversal patterns directed at WordPress plugin URIs
- Correlate plugin-directory requests with unusually large response sizes that may indicate sensitive file exfiltration
- Hunt for subsequent suspicious admin logins following requests that may have leaked wp-config.php
Monitoring Recommendations
- Forward WordPress access logs and PHP error logs to a centralized SIEM for retention and correlation
- Alert on any anonymous access to plugin-handler URIs that previously required authentication
- Monitor for credential reuse and database access patterns inconsistent with the WordPress application
- Track plugin inventory across hosted WordPress sites to identify systems still running <= 3.2.1
How to Mitigate CVE-2026-49061
Immediate Actions Required
- Update WPC Product Options for WooCommerce to a version higher than 3.2.1 once the vendor publishes a patched release
- Rotate WordPress salts, database passwords, and any API keys stored in wp-config.php if exposure is suspected
- Audit access logs from at least 30 days prior for traversal patterns targeting the affected plugin
- Temporarily disable the plugin on WooCommerce stores that cannot be patched immediately
Patch Information
Consult the Patchstack Vulnerability Report for fixed-version details and vendor communications. Apply the update through the WordPress admin Plugins screen or via WP-CLI. After patching, verify the installed version is greater than 3.2.1 and confirm the vulnerable endpoint no longer accepts traversal input.
Workarounds
- Deploy WAF rules blocking requests containing ../, ..%2f, and ..%5c directed at /wp-content/plugins/wpc-product-options/
- Restrict direct access to PHP handlers within the plugin directory using web server rewrite rules
- Set strict filesystem permissions so the web server user cannot read sensitive files outside the document root where feasible
- Move wp-config.php one directory above the web root, a configuration WordPress supports by default
