Descriptions

A flaw was found in Keycloak that prevents certain schemes in redirects, but permits them if a wildcard is appended to the token. This issue could allow an attacker to submit a specially crafted request leading to cross-site scripting (XSS) or further attacks. This flaw is the result of an incomplete fix for CVE-2020-10748.

Este problema podría permitir que un atacante envíe una solicitud especialmente manipulada que dé lugar a cross-site scripting (XSS) o más ataques. Esta falla es el resultado de una solución incompleta para CVE-2020-10748.
