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 DWG file, when parsed through Autodesk AutoCAD and certain AutoCAD-based products, may 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.

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 DWG file parsed by Autodesk AutoCAD and certain AutoCAD-based products can trigger an out-of-bounds write vulnerability during the parsing process. This memory corruption vulnerability can be exploited by a malicious actor to cause application crashes, data corruption, or achieve arbitrary code execution within the context of the current process.

MitigationOrganizations should apply vendor patches from Autodesk for affected AutoCAD products, restrict opening DWG files from untrusted sources, and maintain current software versions.

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 the installed AutoCAD product variant
    Open the AutoCAD application and go to Help > About AutoCAD, or check the application name in the Start menu or installed programs list to determine if it is AutoCAD, AutoCAD Advance Steel, AutoCAD Architecture, AutoCAD Civil 3D, AutoCAD Electrical, AutoCAD LT, AutoCAD Mechanical, or AutoCAD MEP.
    Affected if The installed product is any of the following: AutoCAD, AutoCAD Advance Steel, AutoCAD Architecture, AutoCAD Civil 3D, AutoCAD Electrical, AutoCAD LT, AutoCAD Mechanical, or AutoCAD MEP.
  2. Determine the installed version number
    In the AutoCAD application, type VER or INFO at the command line, or go to Help > About AutoCAD to display the version and build number. Alternatively, check the installed program version in Windows Settings > Apps > Installed Apps.
    Affected if The product is any of the AutoCAD variants listed in the affected products list.
  3. Compare version against affected range
    Compare your installed version to the affected range: version 2025.0.x through 2025.0.x (any 2025 version prior to 2025.1.1) is vulnerable. Version 2025.1.1 and later, or versions 2024 and earlier, are not in the affected range.
    Affected if The installed version is 2025.0.x or any 2025 version prior to 2025.1.1 (for example, 2025.0, 2025.0.1, 2025.0.2, etc.).
  4. Confirm DWG file parsing is accessible
    Verify that the system has the ability to open and parse DWG files. This is the default functionality in AutoCAD products. If DWG file handling has been disabled or restricted through security settings, the attack surface may be reduced.
    Affected if The DWG file parsing feature is enabled and accessible, which is the default state for affected AutoCAD products.

A user is affected if they have any of the listed AutoCAD product variants installed with version 2025.0 through 2025.0.x (prior to 2025.1.1) and the DWG parsing functionality is enabled.

Interim mitigation

Organizations should apply vendor patches from Autodesk for affected AutoCAD products, restrict opening DWG files from untrusted sources, and maintain current software versions.

Recommended fix High confidence

Autocad 2025.1.1 or later

  1. Open Autodesk AutoCAD or the affected AutoCAD-based product
  2. Navigate to Help > Check for Updates, or open the Autodesk Desktop App to check for available updates
  3. Download and install AutoCAD 2025.1.1 (or later) from the official Autodesk website or your Autodesk account
  4. Restart the application after the update completes
  5. Verify the installed version by typing 'ABOUT' in the command line and confirming the version shows 2025.1.1 or later
