CVE-2026-120648

EUVD-2026-116615
CGI versions before 5.00 for Perl allow HTML injection via text containing --> in comment.

Arguments are placed between <!-- and --> without escaping, so text containing --> closes the comment early.

An application that passes request data to comment can be made to inject HTML into the page.
