This excerpt from the article describes the risk well.

> In Firefox Private Browsing mode, the identifier can also persist after all private windows are closed, as long as the Firefox process remains running. In Tor Browser, the stable identifier persists even through the "New Identity" feature, which is designed to be a full reset that clears cookies and browser history and uses new Tor circuits.

I've been using SSH for ~15 years and never knew about these escape sequences. I'm eagerly awaiting my next hung session so that I can test `~.`. It's much nicer than my current approach of having to close that terminal window.

`setHTML` is meant as a replacement for `innerHTML`. In the use case you describe, you would have never wanted `innerHTML` anyway. You'd want `innerText` or `textContent`.

> We’re gradually transitioning the AWS European Sovereign Cloud to be operated exclusively by EU citizens located in the EU. During this transition period, we will continue to work with a blended team of EU residents and EU citizens located in the EU.

I find it fascinating that the goal is to staff this exclusively with EU citizens, thereby excluding non-citizen residents of the EU.

The docs explicitly describe this cloud's independence from the US.

> The AWS European Sovereign Cloud will be capable of operation without dependency on global AWS systems so that the AWS European Sovereign Cloud will remain viable for operating workloads indefinitely even in the face of exceptional circumstances that could isolate the AWS European Sovereign Cloud from AWS resources located outside the EU, such as catastrophic disruption of transatlantic communications infrastructure or a military or geopolitical crisis threatening the sovereignty of EU member states.

I work on security at PostHog. We resolved these SSRF findings back in October 2024 when this report was responsibly disclosed to us. I'm currently gathering the relevant PRs so that we can share them here. We're also working on some architectural improvements around egress, namely using smokescreen, to better protect against this class of issue.
