High [CVE-2024-1132] path transversal in redirection validation

A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks.

This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL. 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 as having a Low impact. Red Hat severity: Important — CVSS 8.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N).

Weakness: CWE-22.
