Data leakage across chats

[schiste]

With gpt-5-codex I have information leakage across chats. I mentioned one specific file in one chat that holds some information specific to a task and all the other chats starts referring to it. While I never told them about that file.

I don't know if I'm the only one, but it is a bit scary if information from one chat gets used in another context.

Additional information : "You’re right—you didn’t bring it up explicitly. I saw FILE.md listed under your “Active file” context, so I assumed that was the work you wanted to tackle. Sorry for the confusion. If you point me to the specific tasks or file you want to focus on now, I’ll switch gears accordingly."

This is new, is there a way to turn that option down? Switching off auto context seems the way to go but I'm not sure what else would be removed?
