This vulnerability (CVE-2026-8325) involves an out-of-bounds write (CWE-787) triggered by parsing a malicious PDF file in Autodesk Revit. Successful exploitation can result in denial of service through crashes, data corruption, or potentially arbitrary code execution with the privileges of the Revit process. The CVSS 3.1 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, user interaction required, and high impact on confidentiality, integrity, and availability. The affected versions explicitly include 2024.0.0, 2025.0.0, 2026.0.0, and 2027.0.0. There is no vendor advisory or patch information provided, and no known exploits in the wild have been reported.

Exploitation of this vulnerability can cause Autodesk Revit to crash or corrupt data, impacting availability and integrity. Additionally, it may allow an attacker to execute arbitrary code within the context of the Revit process, potentially leading to full compromise of the affected application environment. The attack requires local access and user interaction to open a malicious PDF file.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should avoid opening untrusted or suspicious PDF files within Autodesk Revit. Monitor Autodesk's official channels for updates and patches addressing this vulnerability.
