{"cve":"CVE-2026-13492","nvd":{"published":"2026-07-09T19:17:03.883","modified":"2026-07-10T15:43:30.330","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-22"],"references":["https://github.com/AyeCode/userswp/commit/ddb17ad30ff3384cda85c5f372db30b03bd45ac8","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.65/includes/class-forms.php#L1059","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.65/includes/class-forms.php#L1973","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.65/includes/class-forms.php#L2320","https://plugins.trac.wordpress.org/browser/userswp/tags/1.2.65/includes/class-forms.php#L2323"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:44:02.134301115+00:00"},"epss":{"cve":"CVE-2026-13492","score":0.00685,"percentile":0.52597,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
