[bounty] OverlayFS to Root and Parallels Desktop Escapes

Day[0]

More bug bounty style bugs, but you'd be forgiven reading that title thinking we had a low-level focus this episode. We got some awesome bugs this week though from tricking Dependabot and abusing placeholder values, an IIS auth bypass. Ending off with a kernel bug (OverlayFS) and a VM escape (Parallels Desktop)
