Apache HTTP Server 2.4.65 and earlier with Server Side Includes (SSI) enabled and mod_cgid (but not mod_cgi) passes the shell-escaped query string to #exec cmd="..." directives.
This issue affects Apache HTTP Server before 2.4.66.
Users are recommended to upgrade to version 2.4.66, which fixes the issue.
