No, the code is a fake exploit I wrote in 5 minutes because I don't want to publish the real exploit but you can figure out what I mean. The BAI code that this would attack is what I linked on your repo.

Luckily, thanks to fetch, you don't seem to have a supply chain outside the browser itself at a glance so in this particular extension the only way to inject the exploit would be to either introduce a dependency in a PR on your repo and then attack that, or introduce the first 4 lines of the exploit in an obscured way directly into your codebase.

However, if you normalize people installing extensions then it will be more likely that they will install other extensions that may have a much more vulnerable supply chain and with vibe coding nowadays this risk becomes much larger. For example, I could create BAI++ which looks nicer and has the vulnerability and then, when I have 10k installs, I activate the exploit.

Because there is no protection against this (extensions ignore SCP) the only solution for the past decade has been to tell everyone to never use extensions, and it still is the only solution today.
