What is CVE-2026-13492?
CVE-2026-13492 is a high-severity path traversal vulnerability in stiofansisland UsersWP – Front-end login form, User Registration, User Profile & Members Directory plugin for WP, published on 9 Jul 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official 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.
Weakness: CWE-22
