CVE-2026-102112 · Severity: high · CVSS 7.8 · Published 2026-09-30

Kiteworks Core is a secure file transfer and collaboration appliance used by enterprises. An attacker with access to an unprivileged backend service account on the appliance can escalate their privileges to root, allowing them to run arbitrary commands and take complete control of the system. This requires the attacker to already have local access to a service account on the appliance.

## Technical details

A privilege escalation flaw in Kiteworks Core before 9.5.0 allows local escalation from an unprivileged backend service account to root via OS command injection (CWE-78, CWE-269). The vulnerability requires an attacker to have existing local code execution as a service account on the appliance, with no additional user interaction or elevated privileges needed to trigger the escalation. Upgrade to version 9.5.0 or later to remediate.
