This CVE was published Jul 09, 2026 and is one of 17 known issues for this plugin.
Update, patch or deactivate.
No fixed release is identified. Update UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP when a release after 1.2.65 becomes available; until then, disable and remove it when the site's risk warrants. The official upstream changelog lists version 1.2.71, which is newer than the published affected range. Its changelog does not clearly confirm this specific fix, so it is not counted as a known-safe release.
No confirmed safe version is listed. Consider a vendor-supported patch or temporarily restricting the affected functionality while you assess the risk.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
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.
