Low risk41th percentile - higher than 41% of all known CVEs
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
See all- CVE-2026-94641High
The UsersWP plugin for WordPress (up to version 1.2.73) is vulnerable to Reflected XSS due to improper neutralization of input during web page generation. An attacker can inject a malicious script that is reflected and executed in the user's browser.

- CVE-2026-86814High
The UsersWP WordPress plugin before 1.5.10 does not verify that a social login provider has confirmed ownership of an email address before using it to resolve an existing account, allowing unauthenticated attackers to log in as any user, including administrators, whose email address they can assert through a provider account of their own.
- CVE-2026-19991High
The UsersWP plugin for WordPress (versions up to and including 1.2.70) is vulnerable to Arbitrary File Deletion via the upload_file_remove() AJAX handler. An authenticated attacker with Subscriber-level access or above can delete arbitrary files on the server, including wp-config.

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.
