I think I'm not getting something here. Like, sure, the refused prompt "review the code for security issues" could be interpreted as an attempt to discover weaknesses in a running system to exploit them. But we don't generally assume humans are doing something wrong if they are "reviewing code for security issues", and would commonly see no problem with asking each other to do so.
The problem is that a patch to fix a security issue quite often also shines a spotlight on the issue being fixed. Fixing a part of something like this super complicated Project Zero post might not give much of a clue as to what the issue was or how to exploit it: https://projectzero.google/2021/12/a-deep-dive-into-nso-zero... But that's the exception. Most fixes to security issues point a finger directly at the issue…
Unfortunately this will just involve said teams running their patches over AI first before they're put in the main branch. For businesses it will probably be fine, but would get very expensive for open source projects.
