Remote code execution vulnerability in Google they are not willing to fix
People from outside Google freak out about this because at their company, in 99.9% of companies, running code on an engineer's workstation would immediately be the highest possible level of breach. Said process could silently insert code into repos, corrupt the build environment, replace packages in production, or whatever. If you never worked at a company that took it seriously it is hard to imagine that there are people who do take it seriously, and that it is possible to have technical defenses against committing unreviewed and unapproved code, poisoning the official build toolchain, or surreptitiously changing production software images.
