- CVE-2026-13369High
The Ninja Forms - File Uploads plugin for WordPress up to version 3.3.29 is vulnerable to Arbitrary File Read. The attach_files() function improperly handles a raw attacker-controlled 'files' array, bypassing upload validation, path normalization, and database record creation, allowing an unauthenticated attacker to read arbitrary files on the server.
Original NVD description (English source)
The Ninja Forms - File Uploads plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.3.29. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to read all plugin debug log entries stored in the wp_nf3_log table or permanently delete all rows from that table.
