CVE-2026-102129: CWE-266 Incorrect Privilege Assignment in Kiteworks Core
CVE-2026-102129 is a high-severity vulnerability in Kiteworks Core where the user-provisioning interface fails to verify if an administrator is authorized to assign certain roles. This flaw allows an administrator with delegated permissions limited to role changes to escalate an account to full system-administrator privileges. The vulnerability affects Kiteworks Core versions from initial releases up to but not including 9.5.1.
AI Analysis
Technical Summary
The vulnerability identified as CVE-2026-102129 in Kiteworks Core involves incorrect privilege assignment (CWE-266). Specifically, the user-provisioning interface does not properly verify that the requesting administrator has the entitlement to grant the role being assigned. As a result, an administrator whose delegated permissions cover only role changes can escalate privileges to full system-administrator level. This issue affects versions >=0 and <9.5.1 of Kiteworks Core. The CVSS v3.1 base score is 7.2, reflecting network attack vector, low attack complexity, high privileges required, no user interaction, unchanged scope, and high impact on confidentiality, integrity, and availability.
Potential Impact
An attacker with delegated administrative permissions limited to role changes can exploit this vulnerability to escalate privileges to full system-administrator rights. This could lead to complete compromise of the Kiteworks Core system, including unauthorized access, modification, and disruption of services.
Mitigation Recommendations
No explicit patch or remediation details are provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict delegated administrator permissions carefully and monitor for unauthorized privilege escalations.
