> As the article pointed out, GitHub already publicly documented this vulnerability.
I'm honestly not yet convinced that is enough here - I've fallen victim to this without realizing it - the behaviour here is so far removed from how I suspect most user's mental model of github.com works. For me none of the exposed data is sensitive, but the point remains I was totally unawares it would be retrievable like this.
If the behaviour flies so against the grain, just publishing it in a help doc is not enough I'd argue. The linked article makes the exact same argument:
> "The average user views the separation of private and public repositories as a security boundary, and understandably believes that any data located in a private repository cannot be accessed by public users. Unfortunately, as we documented above, that is not always true. Whatsmore, the act of deletion implies the destruction of data. As we saw above, deleting a repository or fork does not mean your commit data is actually deleted."
