Description Marian Rehak 2026-11-05 13:35:17 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

CGI::Cookie versions before 5.00 for Perl allow cookie attribute injection via unvalidated path, domain and expires values.

The path, domain and expires values are written into the Set-Cookie header without checking for semicolons or control characters.

An application that sets them from request data can be made to add other cookie attributes, such as Domain or SameSite.
