Renew the expired security.txt

Why it matters

A security.txt past its Expires date is treated as stale, so researchers may not trust the contact or may not use it at all. Renewing it takes a minute.

The fix

1. Check that the Contact still reaches a person who reads it, then set Expires to a new date less than a year ahead.
2. Put a reminder in your calendar a month before the new date.

Expires: 2026-12-31T23:59:59Z
