Description

The implementation of cookies for HTTP-based disks formatted them in the XML even if the VIR_DOMAIN_XML_SECURE was not present.

Impact

A read-only client can access potentionally sensitive information in the cookies.

Workaround

Denying access to the readonly libvirt socket will avoid the potential information leak.
