Security readout for executives and security teams

This issue affects the legacy Matt Wright FormMail.pl CGI script. A remote user could abuse the redirect parameter to insert unexpected HTTP headers, enabling HTTP response splitting. Business urgency depends on whether this old script is still publicly reachable. Exposure is most likely in legacy websites still running Matt Wright FormMail.pl 1.92 or earlier as a public CGI form handler. The source bundle does not provide reliable CPE data or a complete affected-version range. Treat this as a targeted legacy exposure issue. It is not KEV-listed in the bundle, but any public FormMail.pl instance should be prioritized for removal or replacement because the software is old and web-facing. Mitigation focus: Inventory public CGI scripts for FormMail.pl and Matt Wright FormMail usage.; Remove or replace obsolete FormMail deployments where possible.; Check vendor or maintainer guidance for fixed versions or recommended replacements..
