CVE-2026-15312: CWE-269 Improper Privilege Management in fassionstorage Propovoice: All-in-One Client Management System
The Propovoice: All-in-One Client Management System WordPress plugin contains a privilege escalation vulnerability in all versions up to and including 1.7.8. The vulnerability arises because the REST endpoint for the create() function does not properly validate the user-supplied role parameter and lacks a capability check before assigning roles. This allows authenticated users with the ndpv_manager capability or higher to create new administrator accounts, resulting in full vertical privilege escalation.
AI Analysis
Technical Summary
CVE-2026-15312 is a privilege escalation vulnerability in the Propovoice: All-in-One Client Management System WordPress plugin. The create() REST endpoint fails to validate the 'role' parameter against an allowlist and does not check for the 'promote_users' capability before passing the sanitized role to WP_User::set_role(). As a result, authenticated users with the 'ndpv_manager' capability, a sub-administrator role granted by the plugin, can create new WordPress users with the administrator role, gaining full administrative privileges. This vulnerability affects all versions up to and including 1.7.8.
Potential Impact
An attacker with ndpv_manager-level access or higher can escalate privileges to administrator by creating new admin user accounts. This compromises the entire WordPress site, allowing full control over site content, settings, and user management. The vulnerability extends the attack surface beyond site administrators to any user granted the ndpv_manager role by the plugin.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict ndpv_manager capability assignments to trusted users only and monitor for unauthorized user creation. Avoid granting ndpv_manager or higher privileges to untrusted users.
