Title
Vim: Arbitrary Code Execution via Python Omni-Completion
Summary
Vim is an open source, command line text editor. Prior to version 9.2.0561, the Python omni-completion script in python3complete.vim for Vim with the +python3 interpreter enabled (and the legacy pythoncomplete.vim for builds with the +python interpreter) executes the import and from statements found in the current buffer through Python's import machinery. Because the buffer's working directory is on sys.path, opening a hostile .py file with a sibling Python package and invoking omni-completion runs that package's top-level code as the editing user. This issue has been patched in version 9.2.0561.

Because the buffer\u0027s working directory is on sys.path, opening a hostile .py file with a sibling Python package and invoking omni-completion runs that package\u0027s top-level code as the editing user.
