CVE-2026-1334

Code execution via crafted EPRT file

Published Feb 16, 2026 · Updated Feb 16, 2026

Out-of-bounds read in SOLIDWORKS eDrawings 2025 SP0 through SP5 and 2026 SP0 allows attackers to execute code via a crafted EPRT file. Dassault Systèmes identifies the EPRT file-reading procedure but has not disclosed the exact function, malformed field, or missing bounds check. Execution requires a user to open the file locally, after which code runs in the eDrawings process context.
