{"cve":"CVE-2026-7567","nvd":{"published":"2026-05-01T10:15:58.080","modified":"2026-06-17T11:02:36.120","status":"Deferred","description":"The Temporary Login plugin for WordPress is vulnerable to Authentication Bypass in versions up to and including 1.0.0. This is due to improper input validation in the maybe_login_temporary_user() function, which fails to verify that the 'temp-login-token' GET parameter is a scalar string before processing it. When the parameter is supplied as an array, PHP's empty() check is bypassed and sanitize_key() returns an empty string, which is then passed as the meta_value to get_users(). WordPress ignores an empty meta_value and returns all users matching the meta_key '_temporary_login_token', allowing authentication without a valid token. This makes it possible for unauthenticated attackers to authenticate as any active temporary login user by sending a single crafted GET request.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-288"],"references":["https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L135","https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L179","https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/options.php#L157","https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L135","https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L179"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:33:09.003606135+00:00"},"epss":{"cve":"CVE-2026-7567","score":0.09246,"percentile":0.95354,"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).
