CVE-2025-8892
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA maliciously crafted PRT file, when parsed through certain Autodesk products, can force a Memory Corruption vulnerability. A malicious actor can leverage this vulnerability to execute arbitrary code in the context of the current process.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA memory corruption vulnerability exists in certain Autodesk products when parsing maliciously crafted PRT files. The vulnerability allows a remote attacker to execute arbitrary code in the context of the current process by supplying a specially crafted PRT file that triggers improper memory handling during parsing.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed Autodesk Shared Components versionOpen Windows Control Panel > Programs and Features, or use 'Get-ItemProperty' PowerShell command to query the registry key for Autodesk Shared Components (typically under HKLM:\SOFTWARE\Autodesk\SharedComponents). Locate the Version or DisplayVersion entry.Affected if The installed version is exactly 2026.3
-
Confirm PRT file parsing capability existsCheck if the installed Autodesk product includes PRT file import or parsing modules. Look for PRT-related DLLs (such as prt*.dll) in the Autodesk installation directory, typically under C:\Program Files\Autodesk\ or within the specific product folder.Affected if PRT parsing DLLs are present on the system
-
Check for recent PRT file activityReview Windows Event Logs (Application log) for entries related to PRT file opening, or check the user's recent documents for .PRT file access timestamps. Alternatively, inspect file associations for .PRT extension pointing to Autodesk software.Affected if PRT files have been opened or processed recently on the affected system
A system is affected if Autodesk Shared Components version 2026.3 is installed AND the PRT file parsing functionality is present or has been used.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUsers should avoid opening PRT files from untrusted sources until Autodesk releases an official patch. Organizations should implement file scanning and sandboxing for incoming PRT attachments.
