A flaw was found in Keycloak Gatekeeper (Louketo). The logout endpoint can be abused to redirect logged-in users to arbitrary web pages. Affected versions of Keycloak Gatekeeper (Louketo): 6.0.1, 7.0.0
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
