Security readout for executives and security teams
Plain-English summary
CVE-2026-1283 is a high-severity flaw in SOLIDWORKS eDrawings. If a user opens a malicious EPRT file, an attacker could run code on that user’s workstation. The main business risk is compromise of engineering workstations and sensitive design data through file-based social engineering.
Executive priority
Treat as a priority workstation risk for engineering environments. It is not described as remotely exploitable without user action, but a successful lure could compromise valuable design systems and data.
Technical view
The issue is a heap-based buffer overflow in the EPRT file reading procedure of Dassault Systèmes SOLIDWORKS eDrawings. CVSS 3.1 is 7.8, with local attack vector, low complexity, no privileges required, and user interaction required. Successful exploitation could affect confidentiality, integrity, and availability.
Likely exposure
Organizations using SOLIDWORKS eDrawings in SOLIDWORKS Desktop 2025 or 2026 should review exposure, especially teams receiving EPRT files from external parties. The provided affected list specifically names Release SOLIDWORKS Desktop 2025 SP0 and 2026 SP0, with default status otherwise marked unaffected.
Exploitation context
The attack requires convincing a user to open a specially crafted EPRT file. The source bundle does not indicate active exploitation, public exploit availability, or inclusion in CISA KEV.
Researcher notes
Evidence is limited to the CVE record and Dassault advisory reference in the source bundle. Do not assume affected builds beyond the named SOLIDWORKS Desktop 2025/2026 eDrawings scope. No source in the bundle confirms exploitation in the wild or a specific patch level.
Mitigation direction
- Check Dassault Systèmes’ advisory for fixed versions or vendor-recommended mitigations.
- Restrict opening EPRT files from untrusted or unexpected sources.
- Prioritize updates for engineering workstations handling external design files.
- Use endpoint controls to limit impact of code execution from user applications.
Validation and detection
- Inventory SOLIDWORKS eDrawings installations and versions across workstations.
- Identify systems running SOLIDWORKS Desktop 2025 SP0 or 2026 SP0.
- Review file-handling workflows for externally supplied EPRT files.
- Confirm remediation status against Dassault Systèmes’ published advisory.
