CVE-2026-4880: CWE-269 Improper Privilege Management in ukrsolution Barcode Scanner (+Mobile App) – Inventory manager, Order fulfillment system, POS (Point of Sale)
The Barcode Scanner (+Mobile App) – Inventory manager, Order fulfillment system, POS (Point of Sale) plugin for WordPress is vulnerable to privilege escalation via insecure token-based authentication in all versions up to, and including, 1.11.0. 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.
AI Analysis
Technical Summary
The Barcode Scanner (+Mobile App) plugin for WordPress suffers from improper privilege management (CWE-269) due to insecure handling of authentication tokens. The plugin trusts a Base64-encoded user ID supplied by users in the token parameter, which can be exploited to leak valid authentication tokens via the 'barcodeScannerConfigs' action. Additionally, the absence of meta-key restrictions on the 'setUserMeta' action enables attackers to update user capabilities arbitrarily. An unauthenticated attacker can spoof the admin user ID to retrieve the admin token and then use it to escalate privileges to administrator level, compromising the system fully.
Potential Impact
Successful exploitation results in unauthenticated attackers gaining full administrative privileges on the affected WordPress site using the vulnerable plugin. This can lead to complete system compromise, including unauthorized access, data manipulation, and control over site functionality. The CVSS 3.1 base score is 9.8, reflecting critical impact on confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch links are currently available. Until a patch is released, it is recommended to disable or remove the vulnerable plugin to prevent exploitation. Monitor vendor communications for updates and apply official fixes promptly once available.
