SCA: security update for org.yamcs:yamcs-core (GHSA-2g95-6x5q-xjwj)

critical Tenable Self-Hosted Container Security Plugin ID 442408

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Yamcs is a mission control framework. Prior to 5.12.7, the Yamcs script evaluation engine for Python
algorithms dynamically compiled and evaluated user-controlled algorithm text using Jython through the
JSR-223 ScriptEngine API without enforcing a secure sandbox, so an authenticated user with the
ChangeMissionDatabase privilege could override an existing Python algorithm's logic through the mission
database REST API and import and execute arbitrary Java classes such as 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. (CVE-2026-46621)

Solution

Update the org.yamcs:yamcs-core library and its related packages to version 5.12.7 or later.
