Vim: OS Command Injection via 'path' completion

Title source: cna
STIX 2.1

Description

Vim is an open source, command line text editor. Prior to version 9.2.0435, an OS command injection vulnerability exists in Vim's :find command-line completion. When the path option contains backtick-enclosed shell commands, those commands are executed during file name completion. Because the path option lacks the P_SECURE flag, it can be set from a modeline, allowing an attacker who controls the contents of a file to execute arbitrary shell commands when the user opens that file in Vim and triggers :find completion. This issue has been patched in version 9.2.0435.
