Code execution via uninitialized DGN parser memory
Published Aug 15, 2025 · Updated Feb 26, 2026
Use of an uninitialized variable in affected Autodesk AutoCAD products 2023 through 2026 allows attackers to execute code via a crafted DGN file. The DGN parser accesses memory before properly initializing it, allowing attacker-controlled file content to influence execution. Exploitation requires a target to open the file or visit a malicious page and can also disclose process data or crash 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.
- Affected versionversion=2023 <2023.1.8
- Affected versionversion=2024 <2024.1.8
- Affected versionversion=2025 <2025.1.3
