From the discussion
A few top-level comments from Hacker News, shortened. Read the full thread on Hacker News.
Cursor has released a security notice: https://cursor.com/blog/claude-code-extension-security-notic...
It looks like they push an update every office day. I'm guessing if I installed 6 months ago and didn't update, that I should be fine?
I think it should be important to note that this affected the Claude Code extension on the Open VSX extension registry (and by extension, the Cursor marketplace). From what is currently known, the build on the official marketplace was/is clean.
