CVE-2026-103682 · Severity: info · Published 2026-11-06

Checkmk is an enterprise monitoring platform that tracks the health and performance of IT infrastructure. When Checkmk monitors systems using the Jolokia agent, login passwords were exposed on the process list where any local user on the server could read them. This password exposure could allow attackers with local access to compromise monitored systems or the monitoring setup itself.

## How to fix

- Fixed in 2.5.0p16, 3.0.0b1

## Technical details

The Jolokia special agent passed login passwords as plain-text command-line arguments, making them visible to any user on the Checkmk server who could list processes (ps command). This affected both explicitly configured passwords and those retrieved from the password store. An attacker with local access could harvest credentials while the agent was running, gaining unauthorized access to monitored resources.

## Affected products

- Checkmk Checkmk 2.5.0 before 2.5.0p16
