CVE-2026-102141— Kiteworks Core Privilege Escalation through External Control of File Name or Path

Quick assessment

Affected
Kiteworks Core
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Kiteworks Core 的两个集群管理操作未对传入的文件路径进行验证，因此，若攻击者已获取集群中某一节点的 root 权限，则可以在另一节点上以 root 身份写入文件并使其在该节点上执行。利用此漏洞需要攻击者拥有集群节点的后台 root 权限，且目标节点上存在待应用的软件补丁。

Vulnerability Title
Kiteworks Core Privilege Escalation through External Control of File Name or Path
Source: CVE Program / CVE List V5
Vulnerability Description
Two Kiteworks Core cluster-management operations did not validate file paths supplied to them, so an attacker holding root on one node of a cluster could write files as root onto another node and cause them to be executed there. Exploitation requires backend root access on a cluster node and a pending software patch present on the target node.
