CVE-2026-13369: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in SaturdayDrive Ninja Forms - File Uploads
The Ninja Forms - File Uploads plugin for WordPress is vulnerable to Arbitrary File Read via the attach_files() function in versions up to, and including, 3.3.29. This is due to the get_files_for_attachment() function accepting a raw attacker-controlled 'files' array when the process() method returns early due to a client-supplied saveProgress flag, bypassing all upload validation, path normalization, and database record creation steps, and allowing an attacker-supplied file_path value to reach wp_mail() as an email attachment with only a file_exists() check. This makes it possible for unauthenticated attackers to read arbitrary files on the affected site's server.

Technical Summary
CVE-2026-13369 is a path traversal vulnerability (CWE-22) in the Ninja Forms - File Uploads WordPress plugin by SaturdayDrive. The issue occurs in versions up to and including 3.3.29, where the attach_files() function accepts a raw attacker-controlled 'files' array when the process() method returns early due to a client-supplied saveProgress flag.

This enables unauthenticated attackers to read arbitrary files on the affected server.
Potential Impact
An unauthenticated attacker can read arbitrary files on the server hosting the vulnerable Ninja Forms - File Uploads plugin. This can lead to disclosure of sensitive information, potentially including configuration files, credentials, or other private data. The vulnerability does not allow modification or denial of service but has a high confidentiality impact.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are provided at this time. Until a patch is available, users should consider disabling the vulnerable plugin or restricting access to the affected functionality to trusted users only.
