Simulia Execution Engine
Monthly
Unauthenticated remote code execution in Dassault Systèmes SIMULIA Execution Engine (Release 2023 through Release 2026) allows a network attacker to run arbitrary code on the server by submitting a malicious serialized object that the application deserializes without validation. The flaw carries a maximum CVSS 3.1 base score of 10.0 and requires no privileges or user interaction, making any exposed instance fully compromisable. No public exploit code has been identified at time of analysis and it is not listed in CISA KEV, but the CWE-502 root cause combined with a network attack vector makes it a high-priority patching target.
