Roundcube Vulnerability Update to 1.6.12

Just checking to see if this is something we should consider updating due to the vulnerability in the current version of Roundcube installed by MIAB?

I didn’t explicitly analyse the vulnerabilities, but if they have a CVE number it’s good enough for me to say yes. There is already a pull request so updating should be easy.
