Plain English Summary

AI-powered analysis for quick understanding

This vulnerability allows an attacker to redirect a user's authentication code to a malicious site if they can trick the user into clicking on a specially crafted link. It affects versions of the Pocket ID software before 2.4.0, so users should upgrade to the latest version to protect against this risk.

Technical Description

Pocket ID is an OIDC provider that allows users to authenticate with their passkeys to your services. From 2.0.0 to before 2.4.0, a flaw in callback URL validation allowed crafted redirect_uri values containing URL userinfo (@) to bypass legitimate callback pattern checks. If an attacker can trick a user into opening a malicious authorization link, the authorization code may be redirected to an attacker-controlled host. This vulnerability is fixed in 2.4.0.
