Solid Edge SE2026 Vulnerability Allows Code Execution via PAR Files
The National Vulnerability Database has disclosed CVE-2026-44411, a high-severity vulnerability affecting Solid Edge SE2026, specifically all versions prior to V226.0 Update 5. This flaw stems from uninitialized pointer access during the parsing of specially crafted PAR files.
An attacker exploiting this vulnerability could achieve arbitrary code execution within the context of the current process. This is a critical vector, as it bypasses standard user interaction beyond opening a malicious file, turning a seemingly benign CAD file into a weaponized payload. The CVSS score of 7.8 (High) reflects the significant impact on confidentiality, integrity, and availability.
For defenders, this means a direct threat to engineering workstations and intellectual property. The attacker’s calculus here is clear: target designers and engineers with weaponized project files, gaining a foothold into sensitive networks. This isn’t just about crashing an application; it’s about persistent access and data exfiltration.
What This Means For You
- If your organization uses Solid Edge SE2026, you need to prioritize patching to V226.0 Update 5 or later immediately. Audit your systems for any unpatched instances and implement strict controls around opening PAR files from untrusted sources. This vulnerability directly impacts your ability to prevent unauthorized code execution on critical engineering assets.

CVE-2026-44411 - Solid Edge SE2026 Uninitialized Pointer Access in PAR Parsing
title: CVE-2026-44411 - Solid Edge SE2026 Uninitialized Pointer Access in PAR Parsing
id: scw-2026-05-12-ai-1
status: experimental
level: high
description: |
Detects the execution of Solid Edge (solidedge.exe) when launched by common document applications (like Word or Outlook) and processing a .par file, which is indicative of an attempt to exploit CVE-2026-44411. This vulnerability allows uninitialized pointer access during the parsing of specially crafted PAR files, leading to code execution.
