A flaw was found in Vim’s netrw plugin. Improper sanitization of specially crafted filenames or URLs could allow shell metacharacters to be included in temporary filenames passed to external commands. A local attacker could exploit this issue to trigger unintended shell command execution when a user opens malicious content using affected netrw functionality.

Description OSIDB Bzimport 2026-05-08 23:01:57 UTC 
Vim is an open source, command line text editor. Prior to version 9.2.0383, an OS command injection vulnerability exists in the netrw standard plugin bundled with Vim. By inducing a user to open a crafted URL (e.g., using the sftp:// or file:// protocol handlers), an attacker can execute arbitrary shell commands with the privileges of the Vim process. This issue has been patched in version 9.2.0383.
