CVE-2026-8325

Code execution via crafted PDF parsing

Published Aug 6, 2026 · Updated Aug 6, 2026

Out-of-bounds write in Autodesk Revit 2024, 2025, 2026, and 2027 allows attackers to execute code through a crafted PDF file. Autodesk identifies the PDF parser as the affected component but has not disclosed the malformed structure or memory operation that writes beyond its intended buffer. Exploitation requires user interaction and runs in the current Revit process, where it can corrupt data, crash the application, or execute arbitrary code.
