Security readout for executives and security teams
Plain-English summary
CVE-2026-0874 is a high-severity Autodesk file-parsing flaw. A malicious CATPART file opened or processed by affected Autodesk components could crash the application, corrupt data, or run code with the user’s privileges. Business risk is highest for teams that receive CAD files from external parties.
Executive priority
Prioritize remediation for engineering, design, and partner-facing teams that exchange CAD files. This is not confirmed exploited, but the potential impact includes code execution and data corruption, making timely patch validation appropriate.
Technical view
The issue is an out-of-bounds write (CWE-787) in Autodesk Shared Components 1.9.0.7 when parsing crafted CATPART files through certain Autodesk products. CVSS 3.1 is 7.8: local attack vector, low complexity, no privileges, user interaction required, with high confidentiality, integrity, and availability impact.
Likely exposure
Organizations using Autodesk products that include Shared Components 1.9.0.7 and handle CATPART files are the likely exposure group. Exposure is lower where users do not open untrusted CAD files or where the affected component is absent.
Exploitation context
The provided sources do not indicate active exploitation, and the CVE is not marked KEV. Exploitation requires user interaction: a target must open or process a malicious CATPART file in an affected Autodesk parsing path.
Researcher notes
Key unknowns from the provided sources are the full list of affected Autodesk products and fixed component versions. Treat the vendor advisory as authoritative for product-specific applicability and update paths. Avoid assuming exposure from Autodesk presence alone.
Mitigation direction
- Review Autodesk advisory ADSK-SA-2026-0004 for affected product guidance.
- Use Autodesk Access or vendor-approved channels to apply available Autodesk updates.
- Restrict opening CATPART files from untrusted or unexpected sources.
- Route externally supplied CAD files through established security review workflows.
Validation and detection
- Inventory Autodesk products and Shared Components versions across endpoints.
- Identify systems with Autodesk Shared Components 1.9.0.7 installed.
- Confirm Autodesk updates from the advisory have been applied.
- Review file-handling controls for externally sourced CATPART files.

Out-of-bounds Write
Out-of-bounds Write represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
