CVE-2026-102129: Kiteworks Core privilege escalation in user-provisioning interface

CVE-2026-102129 · Severity: high · CVSS 7.2 · Published 2026-09-30

Kiteworks Core is a secure data exchange and content collaboration platform used by enterprises to protect sensitive communications. An administrative interface failed to validate whether a delegated admin had permission to assign roles, allowing an admin with limited role-change permissions to grant themselves full system-administrator access. An attacker with delegated admin privileges could exploit this to gain complete control of the platform.

Technical details

The user-provisioning interface in Kiteworks Core does not properly verify that a requesting administrator is entitled to grant the role being assigned, an instance of incorrect privilege assignment (CWE-266). An administrator with delegated permissions covering only role changes can exploit this via network access to escalate their own account to full system-administrator privileges. The vulnerability requires high privileges (admin account) and no user interaction; patch available in version 9.5.1.
