| CVE-2024-50312 | 1 Redhat | 1 Openshift Container Platform | 2026-08-11 | N/A | 5.3 MEDIUM |
| A vulnerability was found in GraphQL due to improper access controls on the GraphQL introspection query. This flaw allows unauthorized users to retrieve a comprehensive list of available queries and mutations. Exposure to this flaw increases the attack surface, as it can facilitate the discovery of flaws or errors specific to the application's GraphQL implementation. | |||||
| 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-2024-0775 | 2 Linux, Redhat | 2 Linux Kernel, Enterprise Linux | 2026-08-10 | N/A | 6.7 MEDIUM |
| A use-after-free flaw was found in the __ext4_remount in fs/ext4/super.c in ext4 in the Linux kernel. This flaw allows a local user to cause an information leak problem while freeing the old quota file names before a potential failure, leading to a use-after-free. | |||||
| 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-2026-66757 | 2 Gimp, Redhat | 2 Gimp, Enterprise Linux | 2026-08-10 | N/A | 5.5 MEDIUM |
| A flaw was found in the file-sgi plugin in GIMP. When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions (ysize and zsize) are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value (65535), the multiplication ysize * zsize overflows the standard 32-bit int boundary before being passed to calloc. This integer overflow issue results in undefined behavior, aborting the plugin and causing a denial of service. | |||||
| 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. | |||||
| CVE-2026-15943 | 1 Redhat | 1 Build Of Keycloak | 2026-08-09 | N/A | 5.5 MEDIUM |
| A flaw was found in the Keycloak keycloak-services component, which handles the management of identity providers. The issue occurs when a delegated administrator updates an OIDC identity provider using a masked client secret sentinel value. Due to improper validation, Keycloak reuses the existing real secret even if security-sensitive fields like the token URL have been changed, allowing an attacker to redirect and capture the secret. | |||||
| CVE-2026-18651 | 1 Redhat | 3 389 Directory Server, Directory Server, Enterprise Linux | 2026-08-09 | N/A | 5.4 MEDIUM |
| A flaw was found in 389 Directory Server. During SASL PLAIN authentication, the server installs connection-level bind credentials before performing the account-lock check. If the account is subsequently found to be locked, the bind is reported as failed to the client, but the already-installed authenticated state on the connection is not reverted. A client that supplies valid credentials for an account that has been administratively locked can continue to use the same connection with that account's privileges, defeating account lock as an access-revocation control. | |||||
| CVE-2024-1086 | 5 Debian, Fedoraproject, Linux and 2 more | 27 Debian Linux, Fedora, Linux Kernel and 24 more | 2026-08-07 | N/A | 7.8 HIGH |
| A use-after-free vulnerability in the Linux kernel's netfilter: nf_tables component can be exploited to achieve local privilege escalation. The nft_verdict_init() function allows positive values as drop error within the hook verdict, and hence the nf_hook_slow() function can cause a double free vulnerability when NF_DROP is issued with a drop error which resembles NF_ACCEPT. We recommend upgrading past commit f342de4e2f33e0e39165d8639387aa6c19dff660. | |||||
| CVE-2026-18217 | 1 Redhat | 1 Build Of Keycloak | 2026-08-07 | N/A | 3.4 LOW |
| A flaw was found in the SAML protocol implementation of Keycloak, an open-source identity and access management solution. The issue occurs when Keycloak handles SAML authentication requests using the HTTP-Redirect binding. If a client is configured with a wildcard redirect URL, an attacker can craft a request that includes malicious parameters. When a user authenticates, Keycloak appends its legitimate response to the attacker's parameters. This can cause some service providers to process the attacker's data instead of the real login information, potentially leading to a user being logged into the wrong account. | |||||
