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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
