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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
