AI-suggested
A fix for this vulnerability was implemented around December 26, 2025. Users should verify with the SQLite project for the official patched version of sqldiff.exe and update accordingly. Until then, avoid using the '-L' option with untrusted input to mitigate risk.
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.
