{"cve":"CVE-2026-5957","nvd":{"published":"2026-05-05T04:16:19.643","modified":"2026-06-17T10:59:56.607","status":"Deferred","description":"The EmailKit plugin for WordPress is vulnerable to Arbitrary File Read in all versions up to and including 1.6.5. This is due to a flawed path traversal validation in the create_template() method of the CheckForm class, where realpath() is called on the allowed base directory (wp-content/uploads/emailkit/templates/) which may not exist, causing it to return false. In PHP 8.x, strpos($real_path, false) implicitly converts false to an empty string, and strpos() with an empty needle always returns 0, causing the check strpos(...) !== 0 to evaluate to false and bypassing the path validation entirely. This makes it possible for authenticated attackers, with Author-level access and above, to read arbitrary files from the server, including sensitive files such as wp-config.php, by supplying an absolute path to the emailkit-editor-template REST API parameter.","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:N/A:N","score":6.5},"cwes":["CWE-22"],"references":["https://plugins.trac.wordpress.org/browser/emailkit/tags/1.6.5/includes/Admin/Api/CheckForm.php#L163","https://plugins.trac.wordpress.org/browser/emailkit/tags/1.6.5/includes/Admin/Api/CheckForm.php#L166","https://plugins.trac.wordpress.org/browser/emailkit/tags/1.6.5/includes/Admin/Api/CheckForm.php#L170","https://plugins.trac.wordpress.org/browser/emailkit/tags/1.6.5/includes/Admin/EmailSettings/MetformEmailSettings.php#L252","https://plugins.trac.wordpress.org/browser/emailkit/trunk/includes/Admin/Api/CheckForm.php#L163"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:55.586217763+00:00"},"epss":{"cve":"CVE-2026-5957","score":0.0057,"percentile":0.47179,"date":"2026-10-31"},"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).
