Description The issue allows remote attackers to bypass intended firewall restrictions by using a crafted Content-Type header. This can be achieved with specific Content-Types, such as application/octet-stream and text/xml.

Recommendations For version 10.5, consider restricting or validating the Content-Type header to prevent bypassing of firewall restrictions.
