5.0.HEAD is the most actual, non-released version of the 5.0 code branch. So this means, the problem will be fixed in any new 5.0 release.

Currently there are no plans do do a new 5.0 release. So if security is a real concern for you, you should upgrade to at least 5.5 (which shouldn't be a big deal) or to 6.0.

If you can't upgrade and you must fix the issue, you will need to build from the source (which is a little painful for TC 5.0).

Regards,

Rainer
