Vulnerability details
The vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to command injection in netrw menu construction in runtime/pack/dist/opt/netrw/autoload/netrw.vim when rebuilding bookmarks, history, and targets menus from attacker-controlled directory paths. A remote attacker can supply a specially crafted directory path containing command separators or quotes to execute arbitrary code.
Exploitation requires the GUI version of Vim with the menu bar enabled, and user interaction to browse or bookmark the crafted path so it is recorded in netrw history or bookmarks and the menus are rebuilt.
