CVE-2026-120637

EUVD-2026-116604
CGI versions before 5.00 for Perl take request parameters from the process command line arguments for an unrecognised REQUEST_METHOD.

For a REQUEST_METHOD such as OPTIONS, CGI falls through to its offline debugging mode, which is on by default, and builds the parameters and path_info from the process's command line arguments.
