Notes:

  • This post is written a little different than other posts on the Express blog, but I think it's helpful information for users who may wish to learn more about the vulnerability.
  • Previewing the post, I see that it's styled as an alert on the home page, which I think is due to the Security tag. If that's undesirable, I'd be happy to add a post metadata flag that disables homepage display.

....it's styled as an alert on the home page, which I think is due to the Security tag. If that's undesirable, I'd be happy to add a post metadata flag that disables homepage display.

This seems reasonable given the severity of the issue, but I'll leave it to others who know the details better to make the final call. If we leave the home page warning, consider rewording it to match the first sentence of the post, which makes clearer the impact of the issue... The current text doesn't do that well IMO. See my suggested change.
