I got a midnight message from a volunteer within our local community food group telling me they're taking down some of our servers until this PHP vuln is patched.
If you're in IT or technically proficient, supporting a local mutual aid or charity group is an amazing way of helping out.
(A lot of people ask me how a person who is unable to meet in person or be physically in proximity with others can help out in community groups - this is an amazing way to do that.)
