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 RTE file, when parsed through Autodesk Revit, can force a Heap-Based Overflow vulnerability. 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 · high confidence

A heap-based buffer overflow vulnerability exists in Autodesk Revit when parsing maliciously crafted RTE (Revit Template) files. The vulnerability allows an attacker to trigger memory corruption that can lead to denial of service, sensitive data disclosure, or arbitrary code execution within the context of the running Revit process.

MitigationApply the official Autodesk security update/patch for Revit when available. Until then, exercise caution with untrusted RTE files and consider running Revit in an isolated environment.

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 Revit version
    Open Autodesk Revit, go to Help > About Autodesk Revit, or check the installation via Add/Remove Programs (Windows) to view the installed version number
    Affected if The displayed version falls within any of these ranges: 2024.x (before 2024.3.3), 2025.x (before 2025.4.2), or 2026.x (before 2026.2)
  2. Confirm RTE file handling capability
    Verify that the Revit installation includes the RTE (Revit Template) file import/open functionality, which is a core feature available in all standard installations
    Affected if Revit can open or import .rte template files - this capability is enabled by default in standard installations
  3. Check for recent Revit patches
    In Revit, go to Help > Check for Updates, or check Autodesk Account portal for installed updates
    Affected if No security update specifically addressing CVE-2025-5040 has been installed, or the installed update version is below 2024.3.3, 2025.4.2, or 2026.2 respectively

You are affected if your installed Revit version is 2024.x before 2024.3.3, or 2025.x before 2025.4.2, or 2026.x before 2026.2, and you use the software to open RTE template files.

Fixed in 2024.3.32025.4.22026.2
Interim mitigation

Apply the official Autodesk security update/patch for Revit when available. Until then, exercise caution with untrusted RTE files and consider running Revit in an isolated environment.

Recommended fix Moderate confidence

Revit 2024.3.3 (or later), Revit 2025.4.2 (or later), or Revit 2026.2 (or later depending on your product line)

  1. 1. Identify the current installed version of Autodesk Revit by opening the application and navigating to Help > About Autodesk Revit.
  2. 2. Download the appropriate fixed version from the Autodesk website or your Autodesk Account portal based on your subscription license.
  3. 3. For Revit 2024 users: Upgrade to version 2024.3.3 or later.
  4. 4. For Revit 2025 users: Upgrade to version 2025.4.2 or later.
  5. 5. For Revit 2026 users: Upgrade to version 2026.2 or later.
  6. 6. Before upgrading, back up all existing project files (.rvt, .rte, .rfa) and custom templates to a secure location.
  7. 7. Run the installer as an administrator and follow the on-screen prompts to complete the installation.
  8. 8. After installation, verify the new version by checking Help > About Autodesk Revit.
