CVE-2024-11454

User-assisted code execution via adjacent DLL loading

Published Dec 9, 2024 · Updated Aug 28, 2025

Untrusted DLL loading in Autodesk Revit 2025 before 2025.4 allows attackers to execute arbitrary code through a malicious project directory. When an RVT file is opened, Revit searches its directory through an untrusted path and loads an attacker-supplied DLL as code in the current process. Exploitation requires user interaction and the malicious DLL to be placed beside the RVT file; successful code runs with the Revit process user's access.
