+Subject: [PATCH] patch 9.2.0839: [security]: arbitrary code execution via
+ keyword lookup
+
+Problem:  [security]: arbitrary code execution via keyword lookup in
+          sh.vim, zsh.vim and ps1.vim filetype plugin
+          (manus-use)
+Solution: For powershell, quote the commands using single quotes, for
+          sh/zsh pass the argument as a separate list item to term_start()/system()
+          (Yasuhiro Matsumoto).
