## What is CVE-2026-102141?

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.

The record classifies CVE-2026-102141 under weakness classes [CWE-73](https://intel.threadlinqs.com/cwe/CWE-73), [CWE-269](https://intel.threadlinqs.com/cwe/CWE-269). Its CVSS v3 base vector states that the flaw requires local access to the host, needs high-privilege credentials, needs no user interaction, and has high impact on integrity. 1 affected-product entry is recorded, across 1 vendor, listed below.
