Keycloak vulnerable to Server-Side Request Forgery A flaw was found in Keycloak before 13.0.0, where it is possible to force the server to call out an unverified URL using the OIDC parameter `request_uri`. This flaw allows an attacker to use this parameter to execute a Server-side request forgery (SSRF) attack.

GHSA-97g8-xfvw-q4hg
GMS-2022-8406
Keycloak vulnerable to session takeover with OIDC offline refreshtokens An issue was discovered in Keycloak when using a client with the `offline_access` scope. Reuse of session ids across root and user authentication sessions and a lack of root session validation enabled attackers to resolve a user session attached to a different previously authenticated user. This issue most affects users of shared computers. Suppose a user logs out of their account (without clearing their cookies) in a mobile app or similar client that includes the `offline_access` scope, and another user authenticates to the application. In that case, it will share the same root session id, and when utilizing the refresh token, they will be issued a token for the original user.

Duplicate Advisory: Keycloak Uses a Key Past its Expiration Date # Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-xmmm-jw76-q7vg. This link is maintained to preserve external references. # Original Description A vulnerability was found in Keycloak. Expired OTP codes are still usable when using FreeOTP when the OTP token period is set to 30 seconds (default). Instead of expiring and deemed unusable around 30 seconds in, the tokens are valid for an additional 30 seconds totaling 1 minute. A one time passcode that is valid longer than its expiration time increases the attack window for malicious actors to abuse the system and compromise accounts. Additionally, it increases the attack surface because at any given time, two OTPs are valid.

Duplicate Advisory: Keycloak: Leak of configured LDAP bind credentials ## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-c25h-c27q-5qpv. This link is maintained to preserve external references. ## Original Description A vulnerability was found in Keycloak. The LDAP testing endpoint allows changing the Connection URL  independently without re-entering the currently configured LDAP bind credentials. This flaw allows an attacker with admin access (permission manage-realm) to change the LDAP host URL ("Connection URL") to a machine they control. The Keycloak server will connect to the attacker's host and try to authenticate with the configured credentials, thus leaking them to the attacker. As a consequence, an attacker who has compromised the admin console or compromised a user with sufficient privileges can leak domain credentials and attack the domain.

GHSA-g4gc-rh26-m3p5
Keycloak Open Redirect vulnerability An open redirect vulnerability was found in Keycloak. A specially crafted URL can be constructed where the `referrer` and `referrer_uri` parameters are made to trick a user to visit a malicious webpage. A trusted URL can trick users and automation into believing that the URL is safe, when, in fact, it redirects to a malicious server. This issue can result in a victim inadvertently trusting the destination of the redirect, potentially leading to a successful phishing attack or other types of attacks. Once a crafted URL is made, it can be sent to a Keycloak admin via email for example. This will trigger this vulnerability when the user visits the page and clicks the link. A malicious actor can use this to target users they know are Keycloak admins for further attacks. It may also be possible to bypass other domain-related security checks, such as supplying this as a OAuth redirect uri. The malicious actor can further obfuscate the `redirect_uri` using URL encoding, to hide the text of the actual malicious website domain.

The redirect_uri validation logic allows for bypassing explicitly allowed hosts that would otherwise be restricted An issue was found in the redirect_uri validation logic that allows for a bypass of otherwise explicitly allowed hosts. The problem arises in the verifyRedirectUri method, which attempts to enforce rules on user-controllable input, but essentially causes a desynchronization in how Keycloak and browsers interpret URLs. Keycloak, for example, receives "[www%2ekeycloak%2eorg%2fapp%2f:y@example.com](https://www%2ekeycloak%2eorg%2fapp%2f:y@example.com/)" and thinks the authority to be keycloak.org when it is actually example.com. This happens because the validation logic is performed on a URL decoded version, which no longer represents the original input. ### Acknowledgements Karel Knibbe
