CVE-2025-5036 is a Use-After-Free vulnerability (CWE-416) identified in Autodesk Revit versions 2023 through 2026. The flaw arises when Revit processes a maliciously crafted Revit Family Archive (RFA) file during linking or importing operations. Use-After-Free vulnerabilities occur when a program continues to use memory after it has been freed, leading to undefined behavior. In this case, the vulnerability can be exploited to cause the application to crash, potentially leading to denial of service, or more critically, to read sensitive memory contents or execute arbitrary code within the context of the Revit process. The CVSS 3.1 base score is 7.8, reflecting high severity, with attack vector classified as local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact is high on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploitation requires that a user open or import a malicious RFA file, which could be delivered via social engineering or compromised file sharing. No patches or exploits are currently publicly available, but the vulnerability is published and should be considered a significant risk for users of affected Revit versions.

The vulnerability can have severe consequences for organizations relying on Autodesk Revit for building information modeling and architectural design. Successful exploitation can lead to arbitrary code execution, allowing attackers to gain control over the Revit process, potentially leading to further system compromise. Confidential design data and intellectual property could be exposed or altered, undermining project integrity and confidentiality. Additionally, forced crashes could disrupt workflows, causing denial of service and productivity loss. Since Revit is widely used in architecture, engineering, and construction industries, exploitation could impact critical infrastructure projects and sensitive commercial designs. The requirement for local access and user interaction somewhat limits remote exploitation but does not eliminate risk, especially in environments where files are shared frequently. The lack of known exploits in the wild currently reduces immediate threat but does not preclude future active exploitation.

Organizations should implement strict controls on the handling and sharing of RFA files, especially from untrusted or unknown sources. User training to recognize suspicious files and avoid opening unexpected attachments is critical. Employ application whitelisting and sandboxing techniques to restrict Revit’s ability to execute arbitrary code outside its intended scope. Monitor for updates from Autodesk and apply patches promptly once available. In the absence of patches, consider isolating Revit workstations from untrusted networks and limit user privileges to reduce the impact of potential exploitation. Employ endpoint detection and response (EDR) solutions to detect anomalous behavior indicative of exploitation attempts. Regularly back up critical project data to enable recovery in case of disruption. Finally, coordinate with Autodesk support channels for guidance and early access to fixes.
