CyberRota Analysis
AI-GeneratedA vulnerability exists in the keycloak-services component of Keycloak, specifically affecting the handling of OpenID Connect authentication flows due to inadequate inspection of redirect URLs. This flaw allows attackers to inject duplicate security parameters into the login response, potentially leading to session fixation or account confusion if client applications are misconfigured. Organizations using Keycloak with wildcard redirect URIs should prioritize addressing this issue to safeguard against potential exploitation.
Original NVD Description
A flaw was found in the keycloak-services component of Keycloak, which handles OpenID Connect (OIDC) authentication flows. The issue occurs because the security check designed to prevent HTTP parameter pollution only inspects the query portion of a redirect URL and ignores the fragment portion. When a client is configured with a wildcard redirect URI, an attacker can use this to inject duplicate security parameters into the login response. If a client application is not configured correctly, it might trust the attacker's injected data instead of the real security information from Keycloak, leading to session fixation or account confusion.
