What is CVE-2020-10770?

A vulnerability in Keycloak prior to version 13.0.0 allows an attacker to manipulate the OIDC parameter 'request_uri' to create a Server-side Request Forgery (SSRF) condition. This could enable the attacker to send unauthorized requests from the server, potentially exposing sensitive internal resources. By leveraging this flaw, attackers can exploit the request_uri parameter to make unintended calls to external services or internal network endpoints.
