Code execution via out-of-bounds EPRT parser write
Published Jan 26, 2026 · Updated Jan 26, 2026
Out-of-bounds write in SOLIDWORKS eDrawings 2025 and 2026 allows remote attackers to execute code via a crafted EPRT file. The EPRT parser does not properly validate user-supplied data before writing, so it can write past the end of an allocated object. The target must visit a malicious page or open the file; successful exploitation runs code in the current process.
