| 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-2026-97847 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-06 | 7.1 High |
| A flaw was found in the protocol mapper and identity resolution components of Keycloak. The issue occurs when a client manager uses hardcoded-claim mappers to override identity claims in sessionless service-account tokens. Because these tokens lack a session ID, Keycloak may incorrectly resolve the token bearer as a different, highly privileged user based on the manipulated claims. This can allow an attacker with limited client management permissions to impersonate a realm administrator and gain full control over the realm. | ||||
| CVE-2026-97174 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-11-06 | 6.8 Medium |
| A flaw was found in the Client-Initiated Backchannel Authentication (CIBA) implementation of Keycloak. The CIBA endpoint fails to properly validate the sub parameter, allowing it to be stored as an additional request parameter. During the token issuance process, this injected value overwrites the legitimate subject identifier. This allows an attacker to authenticate as themselves but receive security tokens belonging to a different victim user, leading to unauthorized account access. | ||||
| CVE-2026-96453 | 1 Redhat | 7 Amq Broker, Build Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-11-06 | 8 High |
| A flaw was found in the Keycloak Admin CLI kcadm tool, which is used by administrators to manage Keycloak servers from the command line. When a custom truststore is provided to verify the server identity, the tool incorrectly accepts any self-signed certificate as long as the hostname matches. This allows a network attacker to impersonate the Keycloak server, steal administrative credentials, and perform unauthorized management actions. | ||||
| CVE-2026-93998 | 1 Redhat | 7 Amq Broker, Build Keycloak, Jboss Enterprise Application Platform and 4 more | 2026-11-06 | 7.4 High |
| A flaw was found in the SAML adapter component of Keycloak, which is used to secure applications with SAML-based authentication. The adapter fails to verify that the issuer of a signed SAML assertion matches the expected identity provider configured for the application. If multiple identity providers share the same trusted signing key, an attacker who controls one of those providers can create a validly signed assertion to log into the application as any user, potentially gaining full administrative control. | ||||
| CVE-2026-93569 | 2 Io.netty, Redhat | 23 Netty-codec-http, Amq Broker, Apache Camel Quarkus and 20 more | 2026-11-06 | 8.2 High |
| A flaw was found in Netty. A remote unauthenticated attacker can exploit a vulnerability in Netty's HTTP/1 to HTTP/2 conversion process. When an HTTP/1 request includes both an absolute-form request-target and a conflicting Host header, Netty incorrectly prioritizes the Host header for the HTTP/2 :authority field, discarding the original request-target authority. This inconsistency can allow an attacker to bypass security controls in Netty-based proxies or gateways, potentially leading to unauthorized access, cache poisoning, or misrouting of requests. | ||||
| CVE-2026-93568 | 2 Io.netty, Redhat | 24 Netty-codec-http, Amq Broker, Apache Camel Quarkus and 21 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty. A remote attacker could exploit this vulnerability by sending specially crafted HTTP/2 or HTTP/3 Extended CONNECT requests. Netty's HTTP-object conversion path incorrectly processes these requests as regular HTTP/1.1 CONNECT requests, leading to a loss of critical protocol and path information. This misinterpretation can allow attackers to bypass security policies, such as routing or authorization logic, in applications that rely on Netty for HTTP/2 or HTTP/3 communication, resulting in integrity loss. | ||||
| CVE-2026-93567 | 2 Io.netty, Redhat | 24 Netty-codec-http2, Amq Broker, Apache Camel Quarkus and 21 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty's HTTP/2 codec. When converting HTTP/1 CONNECT requests to HTTP/2, the component incorrectly uses the Host header instead of the CONNECT authority-form request-target for the tunnel authority. A remote attacker can exploit this by supplying a different Host header, leading to a malformed HTTP/2 CONNECT request. This can bypass security controls such as tunnel allow-lists or egress policies, resulting in integrity loss. | ||||
| CVE-2026-93565 | 2 Red Hat, Redhat | 23 Red Hat Amq Broker 7, Amq Broker, Amq Clients and 20 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty RtspDecoder. The `RtspMethods.valueOf()` function incorrectly strips trailing control bytes from method tokens in Real-Time Streaming Protocol (RTSP) requests. A remote attacker can exploit this by sending a specially crafted RTSP request, leading to method-token smuggling. This vulnerability allows an attacker to bypass method-based access controls and can also be used to launder malicious requests through Netty-based RTSP proxies, making them appear legitimate to backend systems. | ||||
| CVE-2026-93564 | 1 Redhat | 20 Amq Broker, Amq Broker 7, Apache Camel Quarkus and 17 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty. A reference-count leak in the HAProxy PROXY-v2 message decoder allows a remote, unauthenticated attacker to send specially crafted PROXY-protocol v2 headers. This can lead to memory exhaustion, resulting in a Denial of Service (DoS) for the affected system. | ||||
| CVE-2026-93558 | 2 Io.netty, Redhat | 24 Netty-codec-http, Amq Broker, Amq Broker 7 and 21 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty's WebSocketServerExtensionHandler. A remote, unauthenticated attacker can exploit this vulnerability by using HTTP/1.1 pipelining to send requests faster than the application can respond. This leads to an unbounded growth of a per-connection queue, consuming excessive memory. Eventually, this can cause the Java Virtual Machine (JVM) to exhaust its heap, resulting in a Denial of Service (DoS) for the affected server. | ||||
| CVE-2026-93491 | 2 Io.netty, Redhat | 23 Netty-codec-http, Amq Broker, Amq Broker 7 and 20 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty's HttpServerCodec. A remote, unauthenticated attacker can exploit this vulnerability by pipelining HTTP/1.1 requests on a single connection and withholding reads. This action causes the methodOverflowQueue to grow without limit, leading to unbounded heap memory consumption and a denial of service due to memory exhaustion. | ||||
| CVE-2026-93488 | 2 Io.netty, Redhat | 23 Netty-codec-http, Amq Broker, Amq Clients and 20 more | 2026-11-06 | 7.5 High |
| A flaw was found in Netty. SpdySessionHandler accepts an unlimited number of concurrent remote-initiated streams because localConcurrentStreams defaults to Integer.MAX_VALUE and the handler provides no API to change it. A remote peer can open a SPDY connection and send a large number of SYN_STREAM frames with FLAG_FIN=0, causing unbounded heap and direct memory allocation that can lead to JVM OutOfMemoryError and a denial of service. | ||||
| 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-2026-103985 | 2026-11-06 | 7.1 High | ||
| FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.231, the profile form exposes the only_assigned_tickets permission to its non-admin owner, and UsersController::profileSave() adds or removes User::PERM_ONLY_ASSIGNED_TICKETS without checking that the editor is an administrator. A restricted agent can uncheck the option, or submit an ordinary profile save that omits it, to remove the administrator-imposed restriction. The agent can then read and modify conversations assigned to other agents in every mailbox they already belong to. This issue is fixed in version 1.8.231. | ||||
| 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-2026-123962 | 1 Debian | 1 Freedombox | 2026-11-06 | 8.4 High |
| In FreedomBox before 26.15, unprivileged user accounts can read/write files for which they lack permissions by setting the authorized_keys file to be a symlink. NOTE: FreedomBox is a Debian Pure Blend, which means that it distributes its software through Debian repositories. | ||||
| CVE-2026-123491 | 1 Craftcms | 2 Cms, Craft Cms | 2026-11-06 | 8.2 High |
| Craft CMS 4.0.0 before 4.18.9 and 5.0.0 before 5.11.2 contains an SQL injection vulnerability in GraphQL eager-loading: arguments on eager-loadable nodes absent from the public schema are copied into EagerLoadPlan criteria without cleansing. Unauthenticated attackers can supply a parenthesized select argument to inject SQL expressions and read arbitrary database content, including password hashes and session tokens. | ||||
| CVE-2026-103984 | 2026-11-06 | 6.5 Medium | ||
| FreeScout is a self-hosted help desk and shared mailbox. Prior to 1.8.231, when limit_user_customer_visibility is enabled, the load_customer_info AJAX action performs a global lookup using an attacker-controlled customer email and checks only whether the agent can access a separately supplied mailbox. A non-admin agent can name an accessible mailbox and retrieve an unrelated customer's rendered profile without invoking CustomerPolicy::view(). The response can expose names, email addresses, phone numbers, company and job information, postal addresses, social profiles, websites, and confidential internal agent notes. This issue is fixed in version 1.8.231. | ||||
