This is due to the plugin trusting a user-supplied Base64-encoded user ID in the token parameter to identify users, leaking valid authentication tokens through the 'barcodeScannerConfigs' action, and lacking meta-key restrictions on the 'setUserMeta' action. This makes it possible for unauthenticated attackers to escalate their privileges to that of an administrator by first spoofing the admin user ID to leak their authentication token, then using that token to update any user's 'wp_capabilities' meta to gain full administrative access."}], "title": "Barcode Scanner (+Mobile App) <= 1.11.0 - Unauthenticated Privilege Escalation via Insecure Token Authentication", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/a213e844-a0d3-4123-9f72-caef7702804c?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/barcode-scanner-lite-pos-to-manage-products-inventory-and-orders/trunk/src/Core.php?rev=3391688#L498"}, {"url": "https://plugins.trac.wordpress.org/changeset/3506824/barcode-scanner-lite-pos-to-manage-products-inventory-and-orders#file30"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-269 Improper Privilege Management", "cweId": "CWE-269", "type": "CWE"}]}], "metrics": [{"cvssV3_1": {"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"}}], "credits": [{"lang": "en", "type": "finder", "value": "Jude Nwadinobi"}], "timeline": [{"time": "2026-03-26T13:59:05.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-04-15T11:13:44.000Z", "lang": "en", "value": "Disclosed"}]}}}
