CVE-2022-27258: XSS via rpath query param.

Escape URLs provided by the rpath query param in settings modules. This
prevents a possible Cross-Site scripting vulnerability, where an
attacker could inject web scripts and html into the settings form via
the rpath query parameter, and have a user execute the script by
tricking them to clicking a link.
