Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

If you add "'><h1> to either Favorite Tags or Ignored Tags on the home page, it'll insert the HTML into the page and break the page layout. Also, after refreshing the page, some new tags will be added: classpost-tag, titleshow, questions etc.

Though, it isn't critical, but an unexpected behaviour.

That's a cool bug. – Josh K Jan 26 '11 at 16:28

Hehe, nice one. Although tagging it is somewhat of a stretch; I don't see a way for a third party to exploit this :)

Anyhow, this will be fixed in the next build; we already had some client-side tag validation code, it just wasn't used in this situation.
