CGI versions before 5.00 for Perl return request-derived values untainted under taint mode.
CVE-2026-120642
CGI versions before 5.00 for Perl return request-derived values untainted under taint mode. The upload filename, uploadInfo values, some pathinfo and scriptname values, Accept results, and the name lists from urlparam and cookie are returned without the taint flag, as is a cookie named expires from 4.67 on. These values come from regex captures or hash keys, which Perl does not taint, so they pass -T checks unvalidated.
