CVE-2022-3782
Description
A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. An attacker can use this flaw to construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain or possibly conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field.
Statement
Red Hat Build of Quarkus is not impacted as this CVE affects the server-side Keycloak execution but Quarkus only acts as a Keycloak client in its quarkus-keycloak-authorization extension. For this reason Quarkus is marked with Low impact.

Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
