Code execution via out-of-bounds RFA read
Published Jul 22, 2025 · Updated Feb 26, 2026
Out-of-bounds read in Autodesk Revit and Revit LT 2023 through 2026 allows attackers to execute code through a crafted RFA file. The RFA parser reads beyond the intended buffer boundary while processing attacker-controlled file data; Autodesk has not disclosed a deeper code-level locus. A user must open or import the file, after which the current process can crash, disclose sensitive memory, or execute attacker-controlled code.

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 <2024.3.4
- Affected versionversion=2025 <2025.4.3
- Affected versionversion=2026 <2026.2
