Severity High

Affected Packages 1

Fixed Packages 1

A flaw was found in Keycloak in the OAuth 2.0 Pushed Authorization Requests (PAR). Client provided parameters were found to be included in plain text in the KC_RESTART cookie returned by the authorization server's HTTP response to a request_uri authorization request. This could lead to an information disclosure vulnerability.
