phpmyadmin -- XSS and sensitive data leakage

The phpmyadmin development team reports:

Description
Because user SQL queries are part of the URL, sensitive
information made as part of a user query can be exposed by
clicking on external links to attackers monitoring user GET
query parameters or included in the webserver logs.
Severity
We consider this to be non-critical.

Description
A specially crafted attack could allow for special HTML
characters to be passed as URL encoded values and displayed
back as special characters in the page.
Severity
We consider this to be non-critical.
