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.","state":"PUBLISHED","assigner":"Wordfence","published_at":"2026-05-01 10:15:58","updated_at":"2026-05-01 10:15:58"},"problem_types":["CWE-288","CWE-288 CWE-288 Authentication Bypass Using an Alternate Path or Channel"],"metrics":[{"version":"3.1","source":"security@wordfence.com","type":"Primary","score":"9.8","severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","data":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"}},{"version":"3.1","source":"CNA","type":"DECLARED","score":"9.8","severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","data":{"baseScore":9.8,"baseSeverity":"CRITICAL","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"}}],"references":[{"url":"https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/options.php#L157","name":"https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/options.php#L157","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/options.php#L157","name":"https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/options.php#L157","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L135","name":"https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L135","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L179","name":"https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L179","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L135","name":"https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L135","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L179","name":"https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L179","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f97c669b-86c1-4873-a050-76972f494099?source=cve","name":"https://www.wordfence.com/threat-intel/vulnerabilities/id/f97c669b-86c1-4873-a050-76972f494099?source=cve","refsource":"security@wordfence.com","tags":[],"title":"","mime":"","httpstatus":"","archivestatus":"0"},{"url":"https://www.cve.org/CVERecord?id=CVE-2026-7567","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7567","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[{"source":"CNA","vendor":"elemntor","product":"Temporary Login","version":"affected 1.0.0 semver","platforms":[]}],"timeline":[{"source":"CNA","time":"2026-04-30T20:59:11.000Z","lang":"en","value":"Disclosed"}],"solutions":[],"workarounds":[],"exploits":[],"credits":[{"source":"CNA","value":"TANG Cheuk Hei","lang":"en"}],"nvd_cpes":[],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[]},"source_records":{"cve_program":{"containers":{"cna":{"affected":[{"defaultStatus":"unaffected","product":"Temporary Login","vendor":"elemntor","versions":[{"lessThanOrEqual":"1.0.0","status":"affected","version":"0","versionType":"semver"}]}],"credits":[{"lang":"en","type":"finder","value":"TANG Cheuk Hei"}],"descriptions":[{"lang":"en","value":"The Temporary Login plugin for WordPress is vulnerable to Authentication Bypass in versions up to and including 1.0.0.
