AI Analysis
Technical Summary
This vulnerability (CVE-2026-11803) involves an Out-of-Bounds Read (CWE-125) in Autodesk Revit when processing specially crafted PDF files. An attacker can exploit this flaw to cause a crash, read sensitive memory, or execute arbitrary code with the privileges of the Revit application. The affected versions are exactly 2026.0.0 and 2027.0.0. The CVSS v3.1 base score is 7.8, indicating high severity, with attack vector local, low attack complexity, no privileges required, user interaction required, unchanged scope, and high impact on confidentiality, integrity, and availability. There is no vendor-provided patch or official remediation information at this time.
Potential Impact
Successful exploitation can cause denial of service via application crash, unauthorized disclosure of sensitive information, or arbitrary code execution within the context of Autodesk Revit. This can compromise the confidentiality, integrity, and availability of the affected system running the vulnerable Revit versions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, users should exercise caution when opening PDF files from untrusted sources in Autodesk Revit versions 2026.0.0 and 2027.0.0.
