Using the feature to add URLs in the submit page, a user might be able to read any file on the server that is readable by lavaserver and consists of valid yaml. So with this patch the feature is disabled again.

For Debian 8 Jessie, these problems have been fixed in version 2014.09.1-1+deb8u1.

We recommend that you upgrade your lava-server packages.
