Researchers have found two new vulnerabilities in React Server Components while attempting to exploit the patches last week. These are new issues, separate from the critical CVE last week. The patch for React2Shell remains effective for the Remote Code Execution exploit.

did you know that you can conditionally exit an effect? this is useful if you want a subscription to only stay active while some condition is true, and to stay removed while that condition is false. a bit mindbending, but so it is with react!
a code block:

  React.useEffect(() => {
    if (!isActive) {
      return
    }
    textInputWebEmitter.addListener('emoji-inserted', onEmojiInserted)
    return () => {
      textInputWebEmitter.removeListener('emoji-inserted', onEmojiInserted)
    }
  }, [onEmojiInserted, isActive])

the if (!isActive) condition is highlighted as newly added code

in case you missed it, the first react compiler beta dropped among other things is official support for React 17+ so you can try it even with an old React (and yes, version 17 is four years old, which is about seventy five in the javascript years)
