Code execution via BinaryReadSectionHeader stack overflow
Published Aug 4, 2026 · Updated Aug 4, 2026
Stack-based buffer overflow in Autodesk FBX SDK 2020.3.9 allows attackers to execute code by supplying a crafted FBX file. BinaryReadSectionHeader overflows a stack buffer while parsing a binary section header, but Autodesk has not disclosed the malformed field or missing bounds check. Exploitation requires user interaction to parse the file, and resulting code runs with the privileges of the current process.

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.
