| CVE-2025-23367 | 1 Redhat | 8 Build Keycloak, Jboss Data Grid, Jboss Enterprise Application Platform and 5 more | 2026-09-17 | 6.5 Medium |
| A flaw was found in the Wildfly Server Role Based Access Control (RBAC) provider. When authorization to control management operations is secured using the Role Based Access Control provider, a user without the required privileges can suspend or resume the server. A user with a Monitor or Auditor role is supposed to have only read access permissions and should not be able to suspend the server. The vulnerability is caused by the Suspend and Resume handlers not performing authorization checks to validate whether the current user has the required permissions to proceed with the action. | ||||
| CVE-2026-15567 | 1 Redhat | 8 Fuse, Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Els and 5 more | 2026-09-17 | 7.5 High |
| A flaw was found in Wildfly. A remote unauthenticated attacker can trigger OutOfMemoryError as CSIv2Util's GSS token decoder reads an attacker-controlled length field without bounds checking and attempts to allocate a byte array of that size. | ||||
| CVE-2026-15565 | 1 Redhat | 13 Build Of Apache Camel For Spring Boot, Camel Spring Boot, Data Grid 8 and 10 more | 2026-09-17 | 7.5 High |
| A flaw was found in Undertow. A remote attacker can cause Out of Memory on websockets endpoint without authentication on any @ServerEndpoint class that has any @OnMessage method. This allows an attacker to cause Denial of Service attack without authentication and using only a standard WebSocket handshake. | ||||
| CVE-2026-15563 | 1 Redhat | 6 Jboss Enterprise Application Platform, Jboss Enterprise Application Platform Els, Jboss Enterprise Application Platform Expansion Pack and 3 more | 2026-09-17 | 7.4 High |
| A flaw was found in EAP's IIOP. The listener's NameService would accept bind operations without authentication, allowing an attacker to hijack JNDI lookups and binding them to a malicious ORB, achieving MITM or DoS on further invocations. | ||||
| CVE-2026-92358 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-17 | 6.4 Medium |
| A flaw was found in the first broker login flow of Keycloak. When a user confirms an account-linking request from a different browser, a temporary proof is created to validate the link. However, this proof is not properly cleared after the link is established or when the user later manually removes the link. An attacker who controls the external identity can exploit this leftover proof to silently re-establish the link and gain unauthorized access to the victims account without any further confirmation. | ||||
| CVE-2026-18212 | 1 Redhat | 4 Build Keycloak, Jboss Data Grid, Jbosseapxp and 1 more | 2026-09-16 | 7.5 High |
| A flaw was found in the SAML Redirect Binding implementation of Keycloak, an open-source identity and access management solution. The issue occurs because the custom DEFLATE compression and decompression helpers fail to release native zlib memory after use. An unauthenticated attacker can exploit this by sending repeated malformed SAML requests, leading to native memory exhaustion and a denial of service. | ||||
| CVE-2026-79651 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-16 | 7.5 High |
| A flaw was found in the theme localization endpoints of the keycloak-services component, which is the core service responsible for authentication flows and theme management in Keycloak. The issue occurs because the system accepts arbitrary locale tags from unauthenticated requests and stores them in a permanent in-memory cache without limits. An attacker can exploit this by sending a large number of unique locale tags, eventually causing the server to run out of memory and crash. | ||||
| CVE-2026-19607 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-16 | 5.3 Medium |
| A flaw was found in the first-broker-login flow of the keycloak-services component. This component handles the initial authentication and account linking when a user logs in via an external identity provider. The issue allows an attacker to register a matching username on an external provider to trigger a collision in Keycloak, which results in the legitimate user being locked out of their account. | ||||
| CVE-2026-74909 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-16 | 8.1 High |
| Keycloak provides a policy enforcer to protect applications by matching incoming web requests against defined security policies. A flaw was found where the enforcer fails to correctly normalize web addresses that contain special encoded characters, such as those representing semicolons or directory traversal segments. An authenticated user can use these encoded characters to trick the enforcer into applying a less restrictive security policy than intended, potentially gaining unauthorized access to sensitive administrative or private application endpoints. | ||||
| CVE-2026-17526 | 1 Redhat | 4 Build Keycloak, Jboss Data Grid, Jbosseapxp and 1 more | 2026-09-16 | 7.2 High |
| Keycloak is an open-source identity and access management solution. A vulnerability was discovered where a user with the impersonation role can impersonate a realm administrator. This allows the attacker to gain full administrative control over the realm, including the ability to manage users, clients, and roles. | ||||
| CVE-2026-18209 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 3.4 Low |
| A flaw was found in the keycloak-services component of Keycloak, which handles OpenID Connect (OIDC) authentication flows. The issue occurs because the security check designed to prevent HTTP parameter pollution only inspects the query portion of a redirect URL and ignores the fragment portion. When a client is configured with a wildcard redirect URI, an attacker can use this to inject duplicate security parameters into the login response. If a client application is not configured correctly, it might trust the attacker's injected data instead of the real security information from Keycloak, leading to session fixation or account confusion. | ||||
| CVE-2026-19729 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-16 | 4.9 Medium |
| A flaw was found in the key provider component of the keycloak-services library, which is the core engine for the Red Hat Build of Keycloak. The issue occurs because a previous fix for path probing was incomplete, allowing a realm administrator to still submit arbitrary filesystem paths as keystore parameters. This can be used to determine the existence and readability of files on the server, potentially exposing sensitive system information. | ||||
| CVE-2026-16093 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 5.4 Medium |
| Keycloak provides a mechanism called Client Policies to enforce security requirements on clients, such as requiring them to use signed JWTs for authentication. A flaw was discovered where this enforcement can be bypassed. An attacker with valid client credentials can provide a fake, unsigned assertion header that tricks the system into thinking the policy requirements have been met. This allows the attacker to authenticate using simpler methods like a client secret even when the administrator has mandated more secure, signed assertions. | ||||
| CVE-2026-16089 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 5.4 Medium |
| A flaw was found in the keycloak-services component of Red Hat Build of Keycloak. The issue occurs because OAuth 2.0 authorization codes are not properly bound to the client that originally requested them. An attacker who can intercept an authorization code can modify it to be redeemed by their own client, potentially allowing them to obtain access tokens for a victim's identity. | ||||
| CVE-2026-16072 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 4.9 Medium |
| A flaw was found in the organization management component of Keycloak. A delegated administrator with permission to manage organizations can create an invitation for a non-existent email address and then retrieve the secret registration link directly through the application programming interface. By using this link, the administrator can create new user accounts and add them to the organization without having the required user management permissions or access to the invited email account. This allows an administrator to bypass security boundaries and add unauthorized members to an organization. | ||||
| CVE-2026-15945 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 4.3 Medium |
| A flaw was found in the group search functionality of the Keycloak server's administrative API. When Fine-Grained Admin Permissions (FGAP) v2 is enabled, a delegated administrator can bypass access restrictions to view parent groups they are not authorized to see. By searching for a child group they have permission to view, the system incorrectly returns the full details of the parent group in the response, leading to the disclosure of sensitive group attributes and configuration. | ||||
| CVE-2026-79652 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-16 | 5.9 Medium |
| A flaw was found in the JWT Bearer authorization grant implementation within the keycloak-services component of Red Hat Build of Keycloak. This component handles various OAuth2 and OpenID Connect grant types used for issuing access tokens. The issue occurs because the JWT Bearer grant fails to check if a client requires user consent before issuing a token. This allows an authenticated attacker with valid client credentials and a trusted identity provider assertion to bypass the consent requirement and obtain unauthorized access to a user account at a consent-gated client. | ||||
| CVE-2026-18573 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more | 2026-09-16 | 6.5 Medium |
| A flaw was found in the keycloak-services component of Keycloak, which is used for managing authentication and authorization flows. The issue occurs when a realm administrator configures client policies to enforce specific authentication requirements on confidential clients. Due to improper evaluation of the client state during an update operation, an attacker with client management permissions can bypass these security policies by first creating a public client and then updating it to a confidential client with weaker authentication. This can result in the persistence of clients that do not comply with the intended security hardening of the realm. | ||||
| CVE-2026-18572 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 6.5 Medium |
| Keycloak provides authorization services that allow administrators to restrict access to resources based on time policies (for example, only allowing access during business hours). A flaw was discovered where a user can include a fake time value in their authorization request that overrides the actual server time. This allows the user to bypass these time-based restrictions and access protected resources at unauthorized times. | ||||
| CVE-2026-18571 | 1 Redhat | 8 Build Keycloak, Build Of Keycloak, Data Grid and 5 more | 2026-09-16 | 6.6 Medium |
| A flaw was found in the user creation component of Keycloak when Fine-Grained Admin Permissions V2 (FGAP V2) is enabled. This issue allows a sub-administrator with permission to create users to add those users to any group, even groups the sub-administrator is not authorized to manage. This could lead to unauthorized access to sensitive information or elevated privileges for the newly created users. | ||||
