Security readout for executives and security teams
Plain-English summary
CVE-2026-1334 affects SOLIDWORKS eDrawings when reading EPRT files. A malicious EPRT file could trigger arbitrary code execution when a user opens it. The practical business risk is compromise of engineering workstations through file-sharing workflows. The source bundle does not show CISA KEV listing or active exploitation evidence.
Executive priority
Prioritize for engineering and design environments that exchange EPRT files externally. The issue is high severity but requires user interaction. Address through vendor-guided updates and tighter handling of untrusted CAD files.
Technical view
This is a CWE-125 out-of-bounds read in the EPRT file reading procedure of SOLIDWORKS eDrawings. CVSS 3.1 is 7.8: local attack vector, low complexity, no privileges required, user interaction required, and high confidentiality, integrity, and availability impact.
Likely exposure
Organizations using SOLIDWORKS eDrawings in SOLIDWORKS Desktop 2025 SP0 or 2026 SP0 are the relevant exposure group. Risk is highest where users open EPRT files from customers, suppliers, public sources, or email attachments.
Exploitation context
Exploitation requires convincing a user to open a specially crafted EPRT file. The provided sources do not identify public exploit code, active exploitation, or KEV inclusion. Treat the issue as file-borne workstation compromise risk rather than network-wormable exposure.
Researcher notes
The description links arbitrary code execution to an out-of-bounds read during EPRT parsing. Public details in the bundle are limited: no exploit status, proof of concept, or specific patched build is provided. Avoid assuming affected versions beyond the advisory scope.
Mitigation direction
- Check Dassault Systèmes advisory for fixed versions or workarounds.
- Update affected SOLIDWORKS eDrawings installations when vendor guidance provides a fix.
- Restrict opening EPRT files from untrusted or unexpected sources.
- Route external CAD files through established review and scanning workflows.
- Warn engineering users about unsolicited EPRT attachments and downloads.
Validation and detection
- Inventory SOLIDWORKS Desktop and eDrawings versions across engineering workstations.
- Compare installed versions against Dassault Systèmes advisory scope.
- Identify teams that exchange or receive EPRT files externally.
- Review endpoint telemetry for suspicious activity after opening EPRT files.
- Track the vendor advisory for remediation status and version clarification.

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