CVE-2026-1333

Code execution via uninitialized EPRT parser memory

Published Feb 16, 2026 · Updated Feb 16, 2026

Uninitialized memory use in SOLIDWORKS eDrawings 2025 SP0 through SP5 and 2026 SP0 allows attackers to execute code via a crafted EPRT file. The EPRT parser accesses memory before properly initializing it, and the resulting process state permits arbitrary code execution. Exploitation requires the target to open the file or visit a malicious page, and the code runs with the current process's privileges.
