Something like this has happened in the proprietary world: the SolarWinds supply chain attack. IIRC, they were releasing breached versions for about a year, and I think it became known only when the US Government came knocking on SolarWinds door. SolarWinds potentially vetting every employee through HR had zero effect on preventing a supply chain attack.
