Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The @adonisjs/http-server npm package is vulnerable to a regular expression denial of service in its built-in slug route matcher, affecting versions below 8.2.2, and versions 9.0.0 up to but not including 9.1.1. A remote, unauthenticated attacker can send a specially crafted URL to a route that uses router.matchers.slug() on a parameter they control, causing the Node.js event loop to block and preventing the process from serving other requests. Users should upgrade to version 8.2.2 or 9.1.1, which contain the fix.
