The NYT lead on this story was AI fears, but the writeup from Calif is worth reading.
AI assisted security research found a severe, 0-click wormable exploit in WeChat, reported it, and it was fixed before it was used to harm people.

I have for you this morning the disclosure of WeWorm, the zero-click attack against WeChat that reportedly used AI-assisted vulnerability discovery to move from vulnerability to working remote code execution in roughly two days. A pretty scary thought if I may say so. Ted Miracco, CEO of Approov: “The most interesting part of the WeChat exploit isn't the bug; rather, it's the timeline.

Nope. They are real severe and critical vulnerabilities in open source software.
Here's a great writeup from a security company that used AI to find a wormable condition in WeChat, reported it, and got it fixed:
