{"cve":"CVE-2026-6072","nvd":{"published":"2026-05-20T02:16:37.207","modified":"2026-07-24T08:10:00.150","status":"Deferred","description":"The Oliver POS – A WooCommerce Point of Sale (POS) plugin for WordPress is vulnerable to Authorization Bypass Through User-Controlled Key in all versions up to and including 2.4.2.6. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N","score":6.5},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge-user.php#L170","https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge-user.php#L195","https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge-user.php#L231","https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge.php#L1677","https://plugins.trac.wordpress.org/browser/oliver-pos/tags/2.4.2.6/includes/class-pos-bridge.php#L1679"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-6072","score":0.00475,"percentile":0.41061,"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).
