CVE-2025-9454

Code execution via unvalidated PRT object bounds

Published Dec 15, 2025 · Updated Dec 15, 2025

Out-of-bounds read in Autodesk Shared Components before 2026.5 allows attackers to execute code via a crafted PRT file. The PRT parser fails to validate user-supplied object bounds before reading past the end of an allocated object. A user must open the file or visit a malicious page; exploitation runs in the current process and can also expose data or crash it.
