Official Description

Yamcs is a mission control framework. Prior to 5.12.7, a server-side code injection vulnerability existed in the Yamcs algorithm evaluation engine org.yamcs.algorithms.JavaExprAlgorithmExecutionFactory, which dynamically compiled and evaluated user-controlled algorithm text through the Janino compiler without enforcing a secure sandbox, so an authenticated user with the ChangeMissionDatabase privilege could override an existing algorithm's text via the mission database REST API and inject Java code (for example using java.lang.Runtime) to achieve remote code execution on the underlying host operating system. This issue is fixed in versions 5.12.7 and 5.13.0, which disable algorithm editing by default.

Risk Analysis

This critical vulnerability in Yamcs, a mission control framework, allows an authenticated user with specific privileges to inject and execute arbitrary Java code. The flaw stems from the dynamic compilation of user-controlled algorithm text without proper sandboxing, leading to potential remote code execution. With a CVSS score of 9.1, this issue presents a significant risk to the integrity and availability of the affected system.

No public exploit is currently known for this vulnerability. However, its remote exploitability (AV:N) and low attack complexity mean that if an exploit were to emerge, it could be easily leveraged.

Recommended Action

To mitigate this vulnerability, upgrade Yamcs to version 5.12.7 or 5.13.0, which disables algorithm editing by default. Implement strict access controls for users with ChangeMissionDatabase privileges.

Technical Analysis

CVE-2026-44632 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires high privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.1.

The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
