Lifecycle Timeline
3DescriptionCVE.org
A maliciously crafted PDF file, when parsed through Autodesk Revit, can force an Out-of-Bounds Write vulnerability. A malicious actor may leverage this vulnerability to cause a crash, cause data corruption, or execute arbitrary code in the context of the current process.
AnalysisAI
Out-of-bounds write in Autodesk Revit's PDF parser allows arbitrary code execution in the context of the current user process when a maliciously crafted PDF file is opened. The CVSS vector (AV:L/UI:R) confirms exploitation requires local user interaction - a victim must be socially engineered into opening a weaponized PDF. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that a victim user opens a maliciously crafted PDF file using Autodesk Revit - the vulnerable code path is the application's PDF parser. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 7.8 High score is driven by full C/I/A impact, which is consistent with an RCE-class memory corruption flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker crafts a malicious PDF that triggers the out-of-bounds write in Revit's parser, then delivers it to a target architect or engineer via spear-phishing email or a compromised file-sharing platform commonly used in AEC project collaboration. When the victim opens the file in Autodesk Revit, the memory corruption is triggered, potentially yielding code execution under the victim's user account. … |
| Remediation | The primary remediation is to apply the patch referenced in Autodesk security advisory ADSK-SA-2026-0011 (https://www.autodesk.com/trust/security-advisories/adsk-sa-2026-0011). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours: Inventory all Autodesk Revit installations and disable external PDF file handling through application settings or Group Policy; communicate directly to all Revit users warning against opening PDFs from untrusted external sources. …
