The plugin protects its entire /wp-json/pos-bridge/* REST API namespace through the oliver_pos_rest_authentication() permission callback, which uses a loose PHP comparison (==) to compare the attacker-supplied 'OliverAuth' header value against the 'oliver_pos_authorization_token' option. On fresh installations where the admin has not yet completed the connection flow, this option is unset (get_option returns false). Due to PHP's type juggling, the loose comparison '0' == false evaluates to true, allowing an unauthenticated attacker to bypass authentication by sending 'OliverAuth: 0'. This grants full access to all POS API endpoints, enabling attackers to read user data (including administrator details), update user profiles (including email addresses), and delete non-admin users. An admin account email reset can lead to site takeover."}],"title":"Oliver POS <= 2.4.2.6 - Unauthenticated Authorization Bypass Through User-Controlled Key to 'OliverAuth' Header","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/ca6aa922-9c58-445c-b88a-3d1d1c95102c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/trunk/includes/class-pos-bridge.php#L1679"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge.php#L1679"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/trunk/includes/class-pos-bridge.php#L1677"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge.php#L1677"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/trunk/includes/class-pos-bridge-user.php#L170"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge-user.php#L170"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/trunk/includes/class-pos-bridge-user.php#L195"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge-user.php#L195"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/trunk/includes/class-pos-bridge-user.php#L231"},{"url":"https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge-user.php#L231"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-639 Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N","baseScore":6.5,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Hunter Jensen"}],"timeline":[{"time":"2026-05-19T12:03:04.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-20T13:13:44.799243Z","id":"CVE-2026-6072","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-20T13:13:52.305Z"}}]}}
