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 · unedited
A maliciously crafted PRT file, when parsed in opennurbs.dll through Autodesk applications, can force an Out-of-Bound Read. A malicious actor can leverage this vulnerability to cause a crash,read sensitive data, or 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 confidence

A maliciously crafted PRT file parsed by the opennurbs.dll library in Autodesk applications triggers an out-of-bounds read vulnerability. This can allow an attacker to cause a denial of service, read sensitive memory contents, or achieve arbitrary code execution within the context of the current process.

MitigationRestrict processing of untrusted PRT files and apply the vendor patch when available; avoid opening PRT files from untrusted or unverified sources until the fix is deployed.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed Autodesk products
    Check Program Files for Autodesk folders, or open each application and go to Help > About Autodesk [Product] to see the version
    Affected if Any of these products are installed: AutoCAD, AutoCAD Architecture, AutoCAD Electrical, AutoCAD Map 3D, AutoCAD Mechanical, AutoCAD MEP, AutoCAD Plant 3D, or Civil 3D
  2. Determine exact version of the Autodesk product
    In the application, go to Help > About Autodesk [Product] and note the full version number (for example, 2023.1.5)
    Affected if Version is >= 2022 but < 2022.1.5; OR >= 2023 but < 2023.1.6; OR >= 2024 but < 2024.1.4; OR >= 2025 but < 2025.1
  3. Locate the opennurbs.dll file
    Search for opennurbs.dll in the application installation directory, typically under C:\Program Files\Autodesk\[Product]\[Version]\
    Affected if The DLL exists in the product folder, confirming the component is present
  4. Check if PRT file handling is used
    Review whether the user or workflow involves opening or importing PRT files in the Autodesk application
    Affected if PRT files are processed or could be opened by the user in the application

A user is affected if they have any of the listed Autodesk products installed with a version falling within the affected ranges and they process PRT files.

Upgrade available Upgrade to 2022.1.5 / 2023.1.6 / 2024.1.4 or later
Fixed in 2022.1.52023.1.62024.1.4
Interim mitigation

Restrict processing of untrusted PRT files and apply the vendor patch when available; avoid opening PRT files from untrusted or unverified sources until the fix is deployed.

Recommended fix High confidence

Upgrade to AutoCAD 2022.1.5 or later; 2023.1.6 or later; 2024.1.4 or later; or 2025.1 or later (matching your product year)

  1. Identify the current version of the installed Autodesk application (AutoCAD, AutoCAD Architecture, AutoCAD Electrical, AutoCAD Map 3D, AutoCAD Mechanical, AutoCAD MEP, AutoCAD Plant 3D, or Civil 3D)
  2. Determine which product year (2022, 2023, 2024, or 2025) is installed
  3. For AutoCAD 2022: Upgrade to version 2022.1.5 or later
  4. For AutoCAD 2023: Upgrade to version 2023.1.6 or later
  5. For AutoCAD 2024: Upgrade to version 2024.1.4 or later
  6. For AutoCAD 2025: Upgrade to version 2025.1 or later
  7. For other affected products (Architecture, Electrical, Map 3D, Mechanical, MEP, Plant 3D, Civil 3D): Apply the same version threshold based on their product year
  8. Download the update from the official Autodesk website (www.autodesk.com) or use the Autodesk Access application to check for updates
