CVE-2025-71316

critical

Description

SQLite 'sqldiff.exe' does not securely handle the way the Microsoft Windows C runtime converts Unicode characters to ANSI codepages. An attacker could use the '-L' option to load an arbitrary DLL with a crafted command line argument string that results in command line file arguments being misinterpreted as command line options. Fixed on or around 2025-12-26.
