Security Issues
Reporting a security vulnerability? Pick the “Bug Report” category and lay out the issue in as much detail as you can.
Before you write
A short triage list so the right person picks up your message and you get a useful answer the first time round.
- Account problems — email from the address tied to your account so we can find you in our records.
- Lesson errata — paste the URL of the page and the paragraph or code block that looks wrong. Quoting the exact line is faster than describing where it sits.
- Bug reports — note the browser, operating system, and what you were doing when the bug appeared. A screenshot or a short reproduction recipe shaves days off the back-and-forth.
- Security disclosures — see our security testing policy for the rules of engagement and the scope. We treat coordinated disclosure as the default and will tell you when we plan to ship a fix.
- Feedback and feature ideas — say what you were trying to do, not just what you wished the tool did. Knowing the underlying task helps us decide whether the answer is a feature, a docs change, or a different workflow.
We answer in the order tickets arrive, with security and account access bumped to the front of the queue. If you do not hear back inside a week, it is fine to send a polite nudge.
