@adonisjs/http-server is vulnerable to Regular Expression Denial of Service (ReDoS)

Medium Risk
This Affects:
@adonisjs/http-serverTL;DR
The built-in slug route matcher uses a regular expression with overlapping quantifiers. Requests to routes that apply the slug matcher to a parameter can supply crafted input that triggers resource exhausting backtracking. Because route matching runs before middleware, the resulting CPU spike blocks the Node.js event loop even for unauthenticated requests, degrading availability. The fix replaces the slug matcher pattern with one that avoids catastrophic backtracking.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your application defines routes that apply the built-in slug matcher to user controlled parameters.
