CVE-2025-41388

Code execution via unchecked V8 data length

Published Jun 17, 2025 · Updated Jun 18, 2025

Stack-based buffer overflow in Fuji Electric Smart Editor 1.0.1.0 and earlier allows remote attackers to execute code via a crafted V8 file. The V8 parser copies user-supplied data into a fixed-length stack buffer without first validating its length. A target must open the file or visit a malicious page; exploitation runs code in the Smart Editor process context.
