Summary

The UsersWP plugin for WordPress up to version 1.2.65 is vulnerable to arbitrary file deletion. This is due to insufficient validation of file fields in the UsersWP_Validation::validate_fields() function and lack of path canonicalization in the UsersWP_Forms::upload_file_remove() AJAX handler, allowing deletion of any file on the server.

Risk Assessment

An authenticated attacker with Subscriber-level access or higher can delete critical files like wp-config.php, leading to full site compromise and data loss.

Recommendation

Immediately update the UsersWP plugin to the latest available version. If an update is not possible, temporarily disable the plugin until a patch is released.

Other vulnerabilities in UsersWP

CVE-2026-18501Medium
The UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Badge Widget Variable Substitution in all versions up to and including 1.2.69 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Original NVD description (English source)

The UsersWP plugin for WordPress is vulnerable to Arbitrary File Deletion in versions up to, and including, 1.2.65. This is due to insufficient validation of file-field values in the UsersWP_Validation::validate_fields() function (which falls through to sanitize_text_field() for fields of type 'file', leaving directory-traversal sequences intact) combined with the UsersWP_Forms::upload_file_remove() AJAX handler building the deletion target from the uploads basedir concatenated with the attacker-controlled metadata value without any realpath canonicalization or uploads-directory boundary check before calling unlink(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary files on the affected site's server, including wp-config.
