3 Xonitic runs on top of the DarkPlaces Engine. When connecting to a server, the client may download and run QuakeC code for the gameplay. The security policies are:
5 - QC code can't create any symlinks.
6 - QC code can read anything below ~/.xonotic/*/ including stuff pointed-to by symlinks (which, as the game can't create any, would have to have been placed by the user). It cannot read user's private key in ~/.xonotic/*.d0si.
7 - QC code can write anything below ~/.xonotic/data including user's config.
8 - Paths are properly sanitized according to this policy.
9 - QC code can send arbitrary data back anywhere (by using the "connect" command).
11 Therefore, do not put any files you don't want to expose under ~/.xonotic
