| CVE-2026-117691 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-07 | 9.1 Critical |
| A flaw was found in the SAML HTTP-Redirect binding implementation of Keycloak. The issue occurs because the server processes percent-encoded parameter names (like %53AMLResponse) while the signature verification logic only checks literal parameter names. An attacker can use this discrepancy to provide a crafted, unsigned SAML message that the server processes instead of a legitimately signed one, leading to full account takeover of federated users. | ||||
| CVE-2026-9797 | 2 Red Hat, Redhat | 3 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak | 2026-11-06 | 6.5 Medium |
| A flaw was found in Keycloak's administrative services (org.keycloak.services.resources.admin). A highly privileged attacker, authenticated with a 'manage-clients' role, could exploit this vulnerability through several methods, including manipulating client JSON Web Key Sets (JWKS), swapping client authenticator types and resetting secrets, or downloading legitimate signing keys. Successful exploitation allows the attacker to obtain a token with 'realm-admin' role assignments, leading to privilege escalation and potential unauthorized access to sensitive resources. | ||||
| CVE-2026-114232 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 8.1 High |
| A flaw was found in the UserManagedPermissionService of the Keycloak authorization server. The UMA Protection API, which manages user permissions, fails to validate the resourceType field when a user creates a new policy. This allows an attacker to create a policy that applies to resources owned by other users, potentially leading to unauthorized access or modification of sensitive data across the entire realm. | ||||
| CVE-2026-110932 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the theme resource endpoint of Keycloak, an open-source identity and access management solution. The issue occurs because the server fails to validate theme names before using them as keys for an on-disk gzip cache. An unauthenticated attacker can exploit this by sending many requests with unique, fabricated theme names, leading to persistent disk space exhaustion that survives server restarts and causes service disruptions. | ||||
| CVE-2026-82965 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the SAML implementation of Keycloak, an open-source identity and access management solution. The SAML Artifact Resolution and ECP SOAP endpoints do not properly limit the size or complexity of incoming XML requests. An unauthenticated remote attacker can exploit this by sending specially crafted, large XML messages that cause the server to consume excessive memory. This leads to the application running out of memory and crashing, resulting in a denial of service for all users. | ||||
| CVE-2026-107123 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the SAML XML processing component of Keycloak, an open-source identity and access management solution. The issue occurs when the server parses XML documents containing excessively long dateTime or duration values. Because these strings are not properly validated before processing, the XML parser consumes excessive CPU time. An unauthenticated remote attacker can exploit this by sending specially crafted SAML requests to the server, leading to high CPU utilization and a denial of service for all users. | ||||
| CVE-2026-112208 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 8.1 High |
| A flaw was found in the Organization identity-first login flow of the Keycloak authentication server. Keycloak is an open-source identity and access management solution used to secure modern applications and services. The issue occurs when an attacker who belongs to multiple organizations initiates a login and then switches to a registration or password reset path. During this process, a flag indicating a successful login is not properly cleared when the user is removed from the session. An attacker can then provide a victim's username, and the system incorrectly treats the stale flag as proof of the victim's identity. This allows the attacker to bypass authentication and gain full access to the victim's account and connected applications. | ||||
| CVE-2026-110931 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the SAML 1.1 assertion parser of Keycloak, a tool used for identity and access management. The issue occurs when the parser handles a specific element called AuthorityBinding within an authentication statement. Due to an incomplete fix for a previous vulnerability, the parser can enter an infinite loop that consumes all available memory, causing the entire Keycloak service to crash and become unavailable to users. | ||||
| CVE-2026-107602 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the SAML 1.1 XML parsing logic of Keycloak, an open-source identity and access management solution. The issue occurs when the parser encounters unexpected elements within a security token's key information section, causing the processing thread to enter an infinite loop. An unauthenticated remote attacker could exploit this by sending specially crafted requests, leading to 100% CPU usage and a total denial of service that requires a server restart to resolve. | ||||
| CVE-2026-103112 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.5 High |
| A flaw was found in the authentication session handling of the keycloak-services component in Keycloak. The issue occurs because the system fails to verify if an authenticator is valid for the current authentication flow when switching between the standard authentication path and the reset credentials path. An authenticated attacker can exploit this by triggering a race condition during the credential reset process to associate their successful authentication state with another user's session. This can result in the attacker gaining full access to the victim's account and changing their password. | ||||
| CVE-2026-92857 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 8.1 High |
| Keycloak provides a Dynamic Client Registration feature that allows users with specific tokens to register their own applications. A flaw in how Keycloak validates these registration requests allows an attacker to create a malicious application that forges identity information. By mapping their own user profile details to protected fields like the user ID (sub) or intended audience (aud), an attacker can generate signed security tokens that make them appear to be a different user. This could allow an attacker to impersonate other users or gain unauthorized access to services that rely on these tokens for identity verification. | ||||
| CVE-2026-92855 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-06 | 7.4 High |
| A flaw was found in the SAML identity broker component of Keycloak, which is used to delegate authentication to external identity providers. The issue occurs because the broker fails to verify that a user actually possesses the private key associated with a holder-of-key assertion. An attacker who intercepts a victim signed assertion can replay it to gain unauthorized access and impersonate the victim without needing their private key. | ||||
| CVE-2026-118947 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-04 | 4.3 Medium |
| A flaw was found in the UMA resource registration endpoint of the keycloak-services component, which provides the core logic for Keycloak's authorization and identity services. The issue occurs when remote resource management is enabled, allowing an authenticated user with specific permissions to update resources they do not own by providing a target resource ID in a request. This can lead to unauthorized modification of resource configurations, such as names, URIs, and scopes. | ||||
| CVE-2026-118959 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-03 | 5.4 Medium |
| A flaw was found in the required action provider mechanism of Keycloak. The issue occurs when an authorization request includes the kc_action query parameter set to a mandatory action already assigned to the user, such as profile verification or terms and conditions. Due to incorrect handling of application-initiated actions, Keycloak may skip these mandatory challenges and issue an authorization code. This can allow a user to bypass administrative requirements and gain access to the application without completing necessary profile updates or agreeing to terms. | ||||
| CVE-2026-117627 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-03 | 5.4 Medium |
| A flaw was found in the JWT Authorization Grant implementation of the keycloak-services component. When an OIDC or Google identity provider is configured with specific login restrictions, such as claim filtering, these checks are correctly applied during standard browser logins but are skipped during the JWT-based grant flow. This allows an authenticated client to obtain access tokens for a user even if their identity provider claims should have blocked the login. | ||||
| CVE-2026-118425 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-02 | 6.8 Medium |
| A flaw was found in the secure-redirect-uris-enforcer client policy of Keycloak, an identity and access management solution. The issue occurs when the policy is configured to allow loopback addresses, as Keycloak resolves hostnames via DNS during validation. An attacker can bypass domain allowlist restrictions by using a hostname that resolves to a loopback address, potentially allowing the registration of unauthorized redirect URIs. | ||||
| CVE-2026-117688 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-11-02 | 5.3 Medium |
| A flaw was found in the client registration component of Keycloak, an open-source identity and access management solution. When a vault provider is used to store sensitive information, an authenticated client owner can use a specially crafted reference to trick the system into revealing secrets. By updating a client secret to point to a vault entry and then requesting the client configuration, the owner can see the secret value in plain text. This could lead to the exposure of sensitive credentials that the user should not be able to access. | ||||
| CVE-2026-118030 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-10-30 | 4.2 Medium |
| A flaw was found in the HOTP authentication mechanism of the keycloak-services component, which provides identity and access management services. The issue occurs because the system validates a one-time password and updates its internal counter in two separate steps without proper locking. An attacker with a users password could exploit this timing gap to use a single one-time code to log in multiple times simultaneously. | ||||
| CVE-2026-117859 | 2 Red Hat, Redhat | 5 Red Hat Build Of Keycloak 26.4, Build Keycloak, Build Of Keycloak and 2 more | 2026-10-29 | 5.4 Medium |
| A flaw was found in the Pushed Authorization Request PAR implementation of the keycloak-services component. The issue occurs when an authentication flow is restarted, which incorrectly clears the internal markers used to track PAR consumption while leaving the request active. This allows an attacker to reuse the same authorization request to obtain multiple access tokens, bypassing security requirements for single-use requests. | ||||
| 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 | 2026-07-15 | 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. | ||||
