Uncontrolled Search Path Element

Summary

Vim is an open source, command line text editor. Prior to version 9.1.1947, an uncontrolled search path vulnerability on Windows allows Vim to execute malicious executables placed in the current working directory for the current edited file. On Windows, when using "cmd.exe" as a shell, Vim resolves external commands by searching the current working directory before system paths. When Vim invokes tools such as "findstr" for ":grep", external commands or filters via ":!", or "compiler/:make" commands, it may inadvertently run a malicious executable present in the same directory as the file being edited.
