| CVE-2026-16071 | 1 Redhat | 1 Build Of Keycloak | 2026-08-31 | N/A | 5.4 MEDIUM |
| A flaw was found in the LDAP storage provider of Keycloak, which is used to federate user identities from external directories. The issue occurs when a delegated administrator performs a search using a specific LDAP entry Distinguished Name (DN). Due to missing validation, the system allows lookups for users located outside the configured search boundary, leading to the disclosure of account information from unauthorized parts of the directory and unintended importing of those users into local storage. | |||||
| CVE-2026-15573 | 1 Redhat | 4 Build Of Keycloak, Data Grid, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-08-31 | N/A | 8.1 HIGH |
| A flaw was found in Keycloak's Authorization Services. The component responsible for matching request paths to security policies (PathMatcher) does not properly normalize URIs before comparison. By adding extra characters like a trailing slash or matrix parameters to a URL, an attacker can trick the system into applying a less restrictive security policy than intended. This allows an authenticated user to access administrative or restricted areas they should not have permission to see. | |||||
| CVE-2026-14613 | 1 Redhat | 1 Build Of Keycloak | 2026-08-31 | N/A | 4.3 MEDIUM |
| A vulnerability was discovered in Keycloak's administrative interface that allows certain administrators to see information about groups they shouldn't have access to. When the new Fine-Grained Admin Permissions (FGAP v2) are turned on, an administrator who is allowed to see a specific "role" can also see a list of all groups assigned to that role. The system fails to check if the administrator has permission to see those specific groups. This could allow a restricted administrator to discover "hidden" groups and see their details, such as internal names and custom settings, which might contain sensitive deployment information. | |||||
| CVE-2024-7341 | 1 Redhat | 4 Build Of Keycloak, Enterprise Linux, Keycloak and 1 more | 2026-08-27 | N/A | 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-2026-17048 | 1 Redhat | 1 Build Of Keycloak | 2026-08-19 | N/A | 5.5 MEDIUM |
| A flaw was found in the Keycloak Admin REST API, which is used to manage security realms and clients. The issue occurs when the system processes requests for rotated client secrets that are stored in a secure vault. Due to improper boundary enforcement, a delegated administrator with view-only permissions can retrieve the actual resolved secret instead of the vault placeholder, leading to the exposure of sensitive credentials. | |||||
| CVE-2024-10234 | 1 Redhat | 2 Build Of Keycloak, Jboss Enterprise Application Platform | 2026-08-19 | N/A | 6.1 MEDIUM |
| A vulnerability was found in Wildfly, where a user may perform Cross-site scripting in the Wildfly deployment system. This flaw allows an attacker or insider to execute a deployment with a malicious payload, which could trigger undesired behavior against the server. | |||||
| CVE-2026-2603 | 1 Redhat | 1 Build Of Keycloak | 2026-08-18 | N/A | 8.1 HIGH |
| A flaw was found in Keycloak. A remote attacker could bypass security controls by sending a valid SAML response from an external Identity Provider (IdP) to the Keycloak SAML endpoint for IdP-initiated broker logins. This allows the attacker to complete broker logins even when the SAML Identity Provider is disabled, leading to unauthorized authentication. | |||||
| CVE-2026-2366 | 1 Redhat | 1 Build Of Keycloak | 2026-08-18 | N/A | 3.1 LOW |
| A flaw was found in Keycloak. An authorization bypass vulnerability in the Keycloak Admin API allows any authenticated user, even those without administrative privileges, to enumerate the organization memberships of other users. This information disclosure occurs if the attacker knows the victim's unique identifier (UUID) and the Organizations feature is enabled. | |||||
| CVE-2026-3429 | 1 Redhat | 1 Build Of Keycloak | 2026-08-18 | N/A | 4.2 MEDIUM |
| A flaw was identified in the Account REST API of Keycloak that allows a user authenticated at a lower security level to perform sensitive actions intended only for higher-assurance sessions. Specifically, an attacker who has already obtained a victim’s password can delete the victim’s registered MFA/OTP credential without first proving possession of that factor. The attacker can then register their own MFA device, effectively taking full control of the account. This weakness undermines the intended protection provided by multi-factor authentication. | |||||
| CVE-2026-14614 | 1 Redhat | 1 Build Of Keycloak | 2026-08-11 | N/A | 5.4 MEDIUM |
| A flaw was found in the ClientResource component of Keycloak's admin services when Fine-Grained Admin Permissions (FGAP) v2 is enabled. This issue allows a delegated administrator, who should only have limited control over specific clients, to attach or remove hidden client scopes that they are not authorized to see or manage. As a result, an attacker could inject unauthorized data or permissions into the security tokens issued to end-users, potentially tricking other applications into granting higher levels of access than intended. | |||||
| CVE-2026-11986 | 1 Redhat | 1 Build Of Keycloak | 2026-08-11 | N/A | 4.9 MEDIUM |
| A flaw was found in the admin-ui-ext component of Keycloak, which provides extended administrative user interface capabilities. The issue occurs because certain bulk role-removal endpoints fail to perform granular permission checks when deleting role mappings. This allows a delegated administrator with limited permissions to remove highly privileged roles from other users or groups, potentially disrupting administrative access control. | |||||
| CVE-2026-18207 | 1 Redhat | 1 Build Of Keycloak | 2026-08-11 | N/A | 6.5 MEDIUM |
| A flaw was found in the client policy enforcement mechanism of Keycloak. The issue occurs when the system checks group membership by name instead of a unique identifier. An attacker with client management privileges could bypass security policies by joining a group with a matching name in a different part of the group hierarchy, potentially allowing them to register or update clients without following required security hardening profiles. | |||||
| CVE-2026-14781 | 1 Redhat | 1 Build Of Keycloak | 2026-08-11 | N/A | 4.8 MEDIUM |
| A flaw exists in the org.keycloak.broker.oidc package where the OIDC broker incorrectly synchronizes the email_verified claim. When an OIDC identity provider is configured with trustEmail=true and the userinfo endpoint is enabled, Keycloak retrieves the email address from the userinfo response but retrieves the email_verified status exclusively from the id_token. The root cause is a lack of validation ensuring that the email_verified claim in the id_token actually refers to the email address returned by the userinfo endpoint. If these two sources return different email addresses, the id_token's email_verified=true claim is blindly applied to the userinfo email. Exploitation Conditions: The OIDC identity provider must have trustEmail set to true (non-default). The userinfo endpoint must be enabled (default). The attacker must control or have compromised the upstream OIDC provider. Concrete Impact: Mark arbitrary email addresses as verified in the Keycloak database. Bypass email-based security controls or verification workflows. Potential account takeover if the application relies solely on the email_verified flag from the IdP to link accounts. | |||||
| CVE-2026-15572 | 1 Redhat | 1 Build Of Keycloak | 2026-08-10 | N/A | 8.8 HIGH |
| A flaw was found in Keycloak's Dynamic Client Registration (DCR) security policy management. The "Allowed Protocol Mapper Types" policy, which restricts which types of data mappers a client can use, fails to re-validate the mapper type during a client update if the mapper's configuration remains unchanged. An attacker with client registration privileges can exploit this by first registering an allowed mapper type with a malicious configuration and then swapping it for a restricted, high-privilege mapper type (such as one that hardcodes administrative roles). This allows the attacker to gain full administrative access to the Keycloak realm. | |||||
| CVE-2026-16442 | 1 Redhat | 1 Build Of Keycloak | 2026-08-10 | N/A | 7.4 HIGH |
| A flaw was found in the SAML broker component of Keycloak, which is used to manage identity federation and user authentication. The issue occurs because the IdP-initiated Single Sign-On endpoint fails to check if a provider is restricted to account linking only. This allows an attacker with control over a linked upstream identity to bypass login restrictions and gain full access to a local user account. | |||||
| CVE-2026-18967 | 1 Redhat | 2 Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack | 2026-08-10 | N/A | 6.4 MEDIUM |
| A flaw was found in the SAML broker component of Keycloak, an identity and access management solution. When configured as a SAML broker using the IdP-Initiated flow, Keycloak fails to enforce the OneTimeUse condition in SAML assertions. This allows an attacker who captures a valid, unused assertion to replay it multiple times. Successful exploitation could allow an attacker to hijack a user's session and gain unauthorized access to the system as that user. | |||||
| CVE-2026-18569 | 1 Redhat | 1 Build Of Keycloak | 2026-08-10 | N/A | 3.7 LOW |
| A flaw was found in the backchannel logout endpoint of the keycloak-services component, which is part of the Red Hat Build of Keycloak. This component handles authentication and session management for applications. The issue occurs when an OIDC identity provider is configured to skip signature validation. In this specific setup, the system incorrectly accepts logout requests that have no cryptographic signature. An attacker who knows certain technical details about a user's session can use this flaw to force that user to be logged out, potentially disrupting their work. | |||||
| CVE-2026-16443 | 1 Redhat | 1 Build Of Keycloak | 2026-08-10 | N/A | 7.4 HIGH |
| A flaw was found in the SAML metadata import functionality of the keycloak-services component, which is the core engine for identity brokering in Red Hat Build of Keycloak. When importing identity provider metadata that lacks specific usage attributes for keys, the system incorrectly disables signature validation for SAML responses even if a signing certificate is provided. This issue allows an unauthenticated attacker to forge a SAML response and gain unauthorized access to a user account by knowing their external identifier. | |||||
| CVE-2025-12150 | 1 Redhat | 2 Build Of Keycloak, Keycloak | 2026-08-10 | N/A | 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-2026-1609 | 1 Redhat | 1 Build Of Keycloak | 2026-08-09 | N/A | 8.1 HIGH |
| A flaw was found in Keycloak. When the JSON Web Token (JWT) authorization grant preview feature is enabled and a user account is disabled, Keycloak fails to validate the user’s disabled status during JWT authorization grant processing. A remote attacker with low privileges can exploit this improper access control vulnerability by presenting a valid assertion token from an external identity provider to obtain a JWT for a disabled user. This allows unauthorized access to sensitive resources. | |||||
