Because safe_exec only blacklists shell metacharacters such as ; | &amp; &gt; &lt;  $ ~ ?, spaces and quotes survive and the value is word-split into additional acme.sh arguments. An administrator, or any actor able to write settings (for example through the settings-import API), can therefore inject acme.sh options such as &#8211;renew-hook, &#8211;pre-hook or &#8211;post-hook to obtain arbitrary command execution as root at the next Let&#039;s Encrypt cron run, or use &#8211;config-home\/&#8211;cert-home for arbitrary file writes.
