CVE-2026-17550

Crash or disclosure via out-of-bounds file read

Published Jul 29, 2026 · Updated Jul 29, 2026

Out-of-bounds reads in Autodesk AutoCAD, AutoCAD LT, and DWG TrueView 2026 and 2027 allow attackers to crash or disclose data. Autodesk has not disclosed the parser routine or incorrect bounds operation that makes malformed DWG or DXF input trigger the invalid read. Exploitation requires a user to open or otherwise parse a crafted file; Autodesk’s CVSS assessment scores only a process crash, not disclosure.
