Is this the normal procedure on such occasions then? I'll remember for the future if it is
Yes, this has always been the normal procedure to contact contribs if there is a potential security issue, as you will note from reading at the top when you post a new thread:
Don't report security issues here - Contact security at contribs dot org
Don't report problems here - Please report bugs and potential bugs in the bug tracker
Don't ask the same question twice - Please search the forums, your question may have been asked before - Thank You.
Thanks.
