| CVE-2026-15571 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-21 | 7.3 High |
| A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak, a widely used open-source identity and access management solution. The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim's account to an attacker's external identity. This results in a full account takeover, allowing the attacker to log in as the victim. | ||||
| CVE-2025-23366 | 1 Redhat | 4 Hal Management Console, Jboss Data Grid, Jboss Enterprise Application Platform and 1 more | 2026-08-19 | 6.5 Medium |
| A flaw was found in the HAL Console in the Wildfly component, which does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output used as a web page that is served to other users. The attacker must be authenticated as a user that belongs to management groups “SuperUser”, “Admin”, or “Maintainer”. | ||||
| CVE-2026-17048 | 1 Redhat | 7 Build Keycloak, Build Of Keycloak, Data Grid and 4 more | 2026-08-18 | 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-2026-3429 | 2 Keycloak, Redhat | 6 Keycloak, Build Keycloak, Build Of Keycloak and 3 more | 2026-08-18 | 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-2023-44487 | 33 Akka, Amazon, Apache and 30 more | 378 Http Server, Opensearch Data Prepper, Apisix and 375 more | 2026-08-11 | 7.5 High |
| The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. | ||||
| CVE-2021-44228 | 13 Apache, Apple, Bentley and 10 more | 177 Log4j, Xcode, Synchro and 174 more | 2026-08-11 | 10 Critical |
| Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. | ||||
| CVE-2026-14614 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-08-11 | 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 | 4 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-08-11 | 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-2026-16100 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-07 | 6.5 Medium |
| A flaw was found in the user-event metrics recording of Keycloak. When metrics are enabled, the system records raw error messages from failed account operations as Prometheus metric labels. Because these error messages can include user-supplied input like nonexistent client IDs, an authenticated user can create a massive number of unique metric entries, eventually exhausting system memory and causing the service to crash or become unavailable. | ||||
| CVE-2026-16442 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-07 | 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-2026-16443 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-08-07 | 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-2026-18967 | 1 Redhat | 6 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack and 3 more | 2026-08-07 | 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-2026-14209 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Jboss Enterprise Application Platform Expansion Pack and 1 more | 2026-08-05 | 4.3 Medium |
| A vulnerability was discovered in Keycloak's Admin UI extension that allows certain administrative users to bypass security restrictions. When Fine-Grained Admin Permissions (FGAPv2) are enabled, an administrator who should only be able to search for users (but not view their full details) can use a specific "brute-force-user" endpoint to access a user's full profile. This includes sensitive information and security metadata. The issue occurs because the system fails to check if the administrator has the required "view" permission for that specific user when using this particular search path. | ||||
| CVE-2024-12369 | 1 Redhat | 2 Build Keycloak, Jboss Enterprise Application Platform | 2026-08-04 | 4.2 Medium |
| A vulnerability was found in OIDC-Client. When using the RH SSO OIDC adapter with EAP 7.x or when using the elytron-oidc-client subsystem with EAP 8.x, authorization code injection attacks can occur, allowing an attacker to inject a stolen authorization code into the attacker's own session with the client with a victim's identity. This is usually done with a Man-in-the-Middle (MitM) or phishing attack. | ||||
| CVE-2026-18211 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-08-02 | 4.2 Medium |
| A flaw was found in the secure-client-uris client policy executor within Keycloak core services. This component is responsible for enforcing security requirements on client configurations, such as requiring encrypted connections for redirect URIs. Due to an improper check that only looks at the start of a web address rather than properly verifying the host, an attacker can bypass these security restrictions by using a specially crafted domain name. This could allow an attacker to intercept sensitive authentication codes over unencrypted connections. | ||||
| CVE-2026-14781 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-07-29 | 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-2026-1609 | 2 Keycloak, Redhat | 4 Keycloak-quarkus-server, Build Of Keycloak, Jboss Enterprise Application Platform and 1 more | 2026-07-16 | 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. | ||||
| CVE-2025-12799 | 1 Redhat | 3 Jboss Enterprise Application Platform, Jbosseapxp, Red Hat Single Sign On | 2026-07-09 | 6.5 Medium |
| A flaw was found in Jastow. Jastow is vulnerable to Cross-Site Scripting (XSS) attack. If using a set of combined configuration to allow unescaped characters in URL with embedded Undertow and Jastow, a server might be vulnerable to improper input handling. | ||||
| CVE-2026-3260 | 1 Redhat | 10 Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot, Data Grid and 7 more | 2026-07-07 | 5.9 Medium |
| The Undertow web server enforces a default maximum HTTP request entity size limit. Any request (including GET or HEAD) containing a body that exceeds this configurable limit is safely dropped by the server, preventing single-request Resource Exhaustion (Out of Memory) Denial of Service attacks. | ||||
| CVE-2026-11577 | 1 Redhat | 5 Build Of Keycloak, Data Grid, Jboss Enterprise Application Platform and 2 more | 2026-07-03 | 7.2 High |
| The reported behavior does not constitute a privilege escalation. Exploitation requires the attacker to already possess the manage-realm administrative role within the realm-management client. By design, the manage-realm role is intended to be equivalent in administrative authority to realm-admin. A user with manage-realm already has full administrative control over the realm. Therefore, importing users with realm-admin role mappings through POST /admin/realms/{realm}/partialImport does not grant any additional privileges beyond those already held by the administrator and does not represent a security vulnerability. | ||||
