keycloak-services: keycloak-services: Google external access-token exchange bypasses hosted-domain restriction

Keycloak allows users to log in using Google accounts and can be configured to only allow users from specific Google Workspace domains. A flaw was found where the token exchange feature, which allows swapping a Google token for a Keycloak token, does not check these domain restrictions. This mean...

keycloak-services: keycloak-services: Required signed-JWT assertion policy can be bypassed with unsigned assertion headers

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...

resteasy-core: RESTeasy SourceProvider remote unauthenticated file read

A flaw was found in RESTEasy's SourceProvider. This vulnerability allows an unauthenticated attacker to perform an unauthenticated remote file read. By sending a specially crafted XML body with a DOCTYPE declaration referencing external entities to an endpoint that accepts application/xml and...

io.netty/netty-handler: Netty: TLS hostname verification bypass via OpenSSL client path misconfiguration

A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...

keycloak-services: keycloak-services: Broker-originated username collision causes account lockout

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...

keycloak-services: keycloak-services: unauthenticated DoS via unbounded locale caching

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...

keycloak-services: keycloak-services: Privilege escalation via impersonation role allows takeover of realm administrator accounts

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,...

react-router: React Router: Remote Code Execution via prototype pollution in Framework Mode

A flaw was found in React Router when operating in Framework Mode. A remote attacker could exploit an existing prototype pollution vulnerability within the application code. This could lead to unauthorized remote code execution RCE on the server through a two-step attack involving external...

keycloak-services: keycloak-services: Incorrect authorization in admin role-composite deletion allows delegated admin to remove privileged child roles

A flaw was found in the admin REST API of Keycloak, a solution for identity and access management. The issue occurs when a delegated administrator attempts to remove a child role from a composite role. Due to missing authorization checks, an attacker with limited administrative permissions can...

keycloak-services: keycloak-services: Microsoft external access-token exchange bypasses configured tenant

Keycloak provides a way to let users log in using Microsoft accounts while restricting access to a specific organization tenant. A flaw was discovered where this restriction is ignored when using the token exchange feature. This means an attacker with a valid Microsoft token from a completely...

keycloak-services: keycloak-services: OIDC redirect_uri fragment bypass in HTTP parameter pollution check

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. Whe...

kernel: scsi: target: iscsi: Bound iscsi_encode_text_output() appends to rsp_buf

A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target functionality. This vulnerability, a heap overrun, occurs because the iscsiencodetextoutput function does not properly check buffer capacity when processing login requests. A remote attacker could exploit...

kernel: netfilter: nat: use kfree_rcu to release ops

A flaw was found in the Linux kernel's netfilter component, specifically within the Network Address Translation NAT subsystem. This vulnerability involves improper memory management when releasing network filter operation structures. This could potentially allow an attacker to cause a system cras...

kernel: KVM: x86: Don't (re)check L1 intercepts when completing userspace I/O

A flaw was found in the Kernel-based Virtual Machine KVM for x86. This vulnerability occurs when KVM incorrectly re-checks Level 1 L1 intercepts during the completion of userspace I/O emulation for a Level 2 L2 instruction. If the L1 or host userspace modifies I/O interception settings during thi...

CVE-2026-77119

A validly signed NSEC3 from an unrelated sibling zone may be accepted as an insecurity proof, downgrading a secure delegation and letting a forged unsigned answer through. This issue affects BIND 9 versions 9.11.0 through 9.18.50, 9.20.0 through 9.20.27, 9.21.0 through 9.21.25, 9.11.3-S1 through...

CVE-2026-75029

In a query response, an attacker may send named multiple copies of a record that should only exist once such as an SOA record. If the RDATA is the same on all the copies, the record is appended to the in-memory RDATA set, which can cause increased memory usage of the negative cache and possibly...

CVE-2026-19668

A BIND recursive resolver may experience excessive resource consumption if it encounters large numbers of a particular kind of invalid DNSSEC record. Default limits on "max-records-per-type" and "max-types-per-name" help mitigate the exposure. This issue affects BIND 9 versions 9.11.0 through...

CVE-2026-19033

For a secondary zone with transfers restricted by TSIG, named may start to serve the data provided in a zone transfer before the final message with the TSIG signature arrives. This could allow an attacker that does not actually possess a valid TSIG signature to send unauthorized zone contents to ...
