There are many attackers that are just going to feed every commit of every project of interest to them into their LLMs and tell it "determine if this is patching an exploit and if so write the exploit". They don't need targeting clues. They're already watching everything coming out of

Do not make the mistake of modeling the attackers as "some guy in a basement with a laptop who decided just today to start attacking things". There are nation-state attackers. There are other attackers less funded than that but who still may not particularly blink at the plan I described above. Putting out the commit was sufficient to tell them even today exactly what the exploit was and the cheaper AI time gets the less targeting info they're going to need as the just grab everything.

I suggest modeling the attackers like a Dark Google. Think of them as well-funded, with lots of resources, and this is their day job, with dedicated teams and specialized positions and a codebase for exploits that they've been working on for years. They're not just some guy who wants to find an exploit maybe and needs huge hints about what commit might be an issue.
