URL Redirection to Untrusted Site ('Open Redirect')
A flaw was found in the redirect_uri validation logic in Keycloak. This issue may allow a bypass of otherwise explicitly allowed hosts. A successful attack may lead to an access token being stolen, making it possible for the attacker to impersonate other users. This issue affects org.keycloak:keycloak-services versions through 22.0.6, and 23.0.0 through 23.0.2. NOTE: This shares same fix commit as CVE-2023-6134.
CWE-601 - Open Redirect
An open redirect attack employs a URL parameter, HTML refresh tags, or a DOM based location change to exploit the trust of a vulnerable domain to direct the users to a malicious website. The attack could lead to higher severity vulnerabilities such as unauthorized access control, account takeover, XSS, and more.
