CVE-2026-4636 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-04-16 8.1 High
A flaw was found in Keycloak. An authenticated user with the uma_protection role can bypass User-Managed Access (UMA) policy validation. This allows the attacker to include resource identifiers owned by other users in a policy creation request, even if the URL path specifies an attacker-owned resource. Consequently, the attacker gains unauthorized permissions to victim-owned resources, enabling them to obtain a Requesting Party Token (RPT) and access sensitive information or perform unauthorized actions.
CVE-2026-2733 1 Redhat 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more 2026-04-16 3.8 Low
A flaw was identified in the Docker v2 authentication endpoint of Keycloak, where tokens continue to be issued even after a Docker registry client has been administratively disabled. This means that turning the client “Enabled” setting to OFF does not fully prevent access. As a result, previously valid credentials can still be used to obtain authentication tokens. This weakens administrative controls and could allow unintended access to container registry resources.
CVE-2026-0871 1 Redhat 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more 2026-04-16 4.9 Medium
A flaw was found in Keycloak. An administrator with `manage-users` permission can bypass the "Only administrators can view" setting for unmanaged attributes, allowing them to modify these attributes. This improper access control can lead to unauthorized changes to user profiles, even when the system is configured to restrict such modifications.
CVE-2026-3009 1 Redhat 7 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 4 more 2026-04-16 8.1 High
A security flaw in the IdentityBrokerService.performLogin endpoint of Keycloak allows authentication to proceed using an Identity Provider (IdP) even after it has been disabled by an administrator. An attacker who knows the IdP alias can reuse a previously generated login request to bypass the administrative restriction. This undermines access control enforcement and may allow unauthorized authentication through a disabled external provider.
CVE-2026-3047 2 Red Hat, Redhat 7 Red Hat Build Of Keycloak 26.2, Red Hat Build Of Keycloak 26.2.14, Red Hat Build Of Keycloak 26.4 and 4 more 2026-04-16 8.8 High
A flaw was found in org.keycloak.broker.saml. When a disabled Security Assertion Markup Language (SAML) client is configured as an Identity Provider (IdP)-initiated broker landing target, it can still complete the login process and establish a Single Sign-On (SSO) session. This allows a remote attacker to gain unauthorized access to other enabled clients without re-authentication, effectively bypassing security restrictions.
CVE-2026-3121 2 Keycloak, Redhat 8 Keycloak, Build Keycloak, Build Of Keycloak and 5 more 2026-04-15 6.5 Medium
A flaw was found in Keycloak. An administrator with `manage-clients` permission can exploit a misconfiguration where this permission is equivalent to `manage-permissions`. This allows the administrator to escalate privileges and gain control over roles, users, or other administrative functions within the realm. This privilege escalation can occur when admin permissions are enabled at the realm level.
CVE-2026-3190 2 Keycloak, Redhat 3 Keycloak, Build Keycloak, Build Of Keycloak 2026-04-15 4.3 Medium
A flaw was found in Keycloak. The User-Managed Access (UMA) 2.0 Protection API endpoint for permission tickets fails to enforce the `uma_protection` role check. This allows any authenticated user with a token issued for a resource server client, even without the `uma_protection` role, to enumerate all permission tickets in the system. This vulnerability partial leads to information disclosure.
CVE-2025-14778 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-04-15 5.4 Medium
A flaw was found in Keycloak. A significant Broken Access Control vulnerability exists in the UserManagedPermissionService (UMA Protection API). When updating or deleting a UMA policy associated with multiple resources, the authorization check only verifies the caller's ownership against the first resource in the policy's list. This allows a user (Owner A) who owns one resource (RA) to update a shared policy and modify authorization rules for other resources (e.g., RB) in that same policy, even if those other resources are owned by a different user (Owner B). This constitutes a horizontal privilege escalation.
CVE-2025-11537 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-04-15 5 Medium
A flaw was found in Keycloak. When the logging format is configured to a verbose, user-supplied pattern (such as the pre-defined 'long' pattern), sensitive headers including Authorization and Cookie are disclosed to the logs in cleartext. An attacker with read access to the log files can extract these credentials (e.g., bearer tokens, session cookies) and use them to impersonate users, leading to a full account compromise.
CVE-2026-4628 1 Redhat 8 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 5 more 2026-04-02 4.3 Medium
A flaw was found in Keycloak. An improper Access Control vulnerability in Keycloak’s User-Managed Access (UMA) resource_set endpoint allows attackers with valid credentials to bypass the allowRemoteResourceManagement=false restriction. This occurs due to incomplete enforcement of access control checks on PUT operations to the resource_set endpoint. This issue enables unauthorized modification of protected resources, impacting data integrity.
CVE-2026-4633 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-04-02 3.7 Low
A flaw was found in Keycloak. A remote attacker can exploit differential error messages during the identity-first login flow when Organizations are enabled. This vulnerability allows an attacker to determine the existence of users, leading to information disclosure through user enumeration.
CVE-2024-7341 1 Redhat 8 Build Keycloak, Build Of Keycloak, Enterprise Linux and 5 more 2026-04-01 7.1 High
A session fixation issue was discovered in the SAML adapters provided by Keycloak. The session ID and JSESSIONID cookie are not changed at login time, even when the turnOffChangeSessionIdOnLogin option is configured. This flaw allows an attacker who hijacks the current session before authentication to trigger session fixation.
CVE-2024-8883 1 Redhat 10 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform and 7 more 2026-04-01 6.1 Medium
A misconfiguration flaw was found in Keycloak. This issue can allow an attacker to redirect users to an arbitrary URL if a 'Valid Redirect URI' is set to http://localhost or http://127.0.0.1, enabling sensitive information such as authorization codes to be exposed to the attacker, potentially leading to session hijacking.
CVE-2024-4629 1 Redhat 12 Build Keycloak, Build Of Keycloak, Enterprise Linux and 9 more 2026-03-26 6.5 Medium
A vulnerability was found in Keycloak. This flaw allows attackers to bypass brute force protection by exploiting the timing of login attempts. By initiating multiple login requests simultaneously, attackers can exceed the configured limits for failed attempts before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.
CVE-2024-1132 1 Redhat 23 Amq Broker, Build Keycloak, Build Of Keycloak and 20 more 2026-03-17 8.1 High
A flaw was found in Keycloak, where it does not properly validate URLs included in a redirect. This issue could allow an attacker to construct a malicious request to bypass validation and access other URLs and sensitive information within the domain or conduct further attacks. This flaw affects any client that utilizes a wildcard in the Valid Redirect URIs field, and requires user interaction within the malicious URL.
CVE-2025-12150 1 Redhat 3 Build Keycloak, Build Of Keycloak, Keycloak 2026-03-06 3.1 Low
A flaw was found in Keycloak’s WebAuthn registration component. This vulnerability allows an attacker to bypass the configured attestation policy and register untrusted or forged authenticators via submission of an attestation object with fmt: "none", even when the realm is configured to require direct attestation. This can lead to weakened authentication integrity and unauthorized authenticator registration.
CVE-2025-3910 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-01-29 5.4 Medium
A flaw was found in Keycloak. The org.keycloak.authorization package may be vulnerable to circumventing required actions, allowing users to circumvent requirements such as setting up two-factor authentication.
CVE-2024-7318 1 Redhat 2 Build Keycloak, Build Of Keycloak 2026-01-26 4.8 Medium
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.
CVE-2024-7260 1 Redhat 3 Build Keycloak, Build Of Keycloak, Keycloak 2026-01-23 6.1 Medium
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.
CVE-2024-7885 1 Redhat 21 Apache Camel Hawtio, Apache Camel Spring Boot, Build Keycloak and 18 more 2026-01-19 7.5 High
A vulnerability was found in Undertow where the ProxyProtocolReadListener reuses the same StringBuilder instance across multiple requests. This issue occurs when the parseProxyProtocolV1 method processes multiple requests on the same HTTP connection. As a result, different requests may share the same StringBuilder instance, potentially leading to information leakage between requests or responses. In some cases, a value from a previous request or response may be erroneously reused, which could lead to unintended data exposure. This issue primarily results in errors and connection termination but creates a risk of data leakage in multi-request environments.
