AI-suggested
Upgrade affected AdonisJS HTTP Server versions to 8.2.1 or later, or 9.1.0 or later, where the vulnerability is fixed. If upgrading is not immediately possible, implement custom status pages or JSON responses to handle errors instead of relying on the default HTML exception response. Patch status is not explicitly stated in the vendor advisory, but fixed versions are known.
Description
A cross-site scripting (XSS) vulnerability exists in the AdonisJS HTTP Server package versions 8.0.0-next.0 through 8.2.0 and 9.0.0 through 9.0.2. The error.message is directly interpolated into the default HTML exception response without proper escaping, allowing attacker-controlled JavaScript execution when a crafted missing-route URL is accessed and no custom error handling is in place. This issue is fixed in versions 8.2.1 and 9.1.0.
