Threats affecting pkg:github/adonisjs/http-server

AdonisJS HTTP Server is a package for handling HTTP requests in the AdonisJS framework. Prior to 8.2.2 and 9.1.1, the regular expression returned by router.matchers.slug() contains adjacent greedy repetitions with overlapping character classes. When an application applies this matcher to an attacker-controlled route parameter, a long slug ending in a character rejected by the final assertion causes quadratic backtracking and excessive CPU use. Route matching occurs before route and group middleware, so authentication or rate-limiting middleware attached to the route may not prevent an unauthenticated request from blocking the Node.js event loop and stopping the worker from serving unrelated requests or health checks. This issue is fixed in versions 8.2.2 and 9.1.1.

A URL redirection vulnerability (CWE-601) exists in AdonisJS HTTP Server versions prior to 8.2.3 and between 9.0.0 and before 9.3.0. The issue arises because route parameter values are inserted into URLs without proper encoding, allowing attacker-controlled input to create scheme-relative external URLs. This can enable attackers to redirect users to malicious sites, potentially facilitating phishing or abuse of authentication flows. The vulnerability is fixed in versions 8.2.3 and 9.3.0.

A vulnerability in AdonisJS HTTP Server prior to versions 7.8.1 and 8.2.0 allows an attacker to exploit the response.redirect(). back() method. This method improperly trusts the Referer header from incoming requests and redirects users to that URL without validating the host. An attacker who can control the Referer header can redirect users to malicious external sites. This open redirect issue affects all AdonisJS applications using this method in the specified vulnerable versions.
