| CVE-2026-96445 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-23 | 6.8 Medium |
| A flaw was found in the Conditional OTP authenticator of Keycloak, an identity and access management solution. The issue occurs when the system evaluates specific HTTP headers to determine if a one-time password (OTP) should be skipped, but fails to verify if those headers came from a trusted source. This could allow an attacker who already has a user's password to bypass the second-factor authentication by providing a specially crafted header in their request. | ||||
| CVE-2026-96446 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-23 | 4.2 Medium |
| A flaw was found in the Pushed Authorization Request PAR implementation of Keycloak. The issue occurs when the silent authentication path prompt=none is used, which allows the authorization process to skip certain steps if a user is already logged in. Due to this bypass, the security rule that ensures a pushed request URI is used only once is not enforced. An attacker could potentially reuse a request URI to obtain multiple authorization codes for a user who is already signed in, violating security standards like FAPI-2. | ||||
| CVE-2026-95503 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-23 | 6.8 Medium |
| A flaw was found in the Kerberos federation provider of Keycloak, an open-source identity and access management solution. When Kerberos password authentication is used without SPNEGO, the system fails to verify the identity of the Key Distribution Center (KDC) by requesting a server ticket. This allows an attacker on the same network to spoof the KDC and bypass the authentication process, potentially gaining unauthorized access to user accounts. | ||||
| CVE-2026-93573 | 2 Io.netty, Redhat | 21 Netty-codec-http, Amq Broker, Amq Clients and 18 more | 2026-09-22 | 6.5 Medium |
| A flaw was found in Netty's HTTP/1.1 decoder. This vulnerability allows a remote attacker to bypass `Transfer-Encoding` header validation by splitting the `Transfer-Encoding` field across multiple headers, with the last field containing a non-final transfer coding like `gzip` or `deflate`. This bypass can lead to HTTP request smuggling, enabling attackers to bypass security controls, desynchronize request processing, or cause requests to be processed in an unintended context. | ||||
| CVE-2026-93558 | 2 Io.netty, Redhat | 22 Netty-codec-http, Amq Broker, Amq Broker 7 and 19 more | 2026-09-22 | 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-2026-93488 | 2 Io.netty, Redhat | 21 Netty-codec-http, Amq Broker, Amq Clients and 18 more | 2026-09-22 | 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-2026-93562 | 2 Io.netty, Redhat | 21 Netty-codec-http, Amq Broker, Amq Clients and 18 more | 2026-09-22 | 6.5 Medium |
| A flaw was found in Netty's HTTP/1 decoder. Incomplete validation of malformed Transfer-Encoding headers allows a remote attacker to perform HTTP request smuggling. By sending specially crafted HTTP requests, an attacker can inject arbitrary HTTP requests, potentially bypassing security controls or accessing unauthorized resources. | ||||
| CVE-2026-93492 | 2 Io.netty, Redhat | 21 Netty-codec-http2, Amq Broker, Amq Broker 7 and 18 more | 2026-09-22 | 5.3 Medium |
| A flaw was found in Netty's HTTP/2 HpackEncoder. A remote attacker can exploit this by sending HTTP/2 SETTINGS frames with a very large MAX_HEADER_TABLE_SIZE. This causes the HpackEncoder to store an excessive number of unique headers, leading to increased CPU usage and memory consumption, ultimately resulting in a Denial of Service (DoS). | ||||
| CVE-2026-93569 | 2 Io.netty, Redhat | 19 Netty-codec-http, Amq Broker, Apicurio Registry and 16 more | 2026-09-22 | 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-2026-93566 | 2 Red Hat, Redhat | 21 Red Hat Amq Broker 7, Amq Broker, Amq Clients and 18 more | 2026-09-22 | 6.5 Medium |
| A flaw was found in Netty. A remote attacker could exploit this by sending a specially crafted HTTP request that includes control characters within the chunk-size line. This bypasses the intended strict validation, allowing the attacker to inject arbitrary HTTP requests. This vulnerability can lead to HTTP request smuggling, potentially resulting in information disclosure or other unauthorized actions. | ||||
| CVE-2026-93568 | 2 Io.netty, Redhat | 20 Netty-codec-http, Amq Broker, Apicurio Registry and 17 more | 2026-09-22 | 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 | 20 Netty-codec-http2, Amq Broker, Apicurio Registry and 17 more | 2026-09-22 | 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-2026-93491 | 2 Io.netty, Redhat | 21 Netty-codec-http, Amq Broker, Amq Broker 7 and 18 more | 2026-09-22 | 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-2026-93574 | 2 Io.netty, Redhat | 21 Netty-codec-http, Amq Broker, Amq Clients and 18 more | 2026-09-22 | 6.5 Medium |
| A flaw was found in Netty's `netty-codec-http` component. A remote attacker could exploit this vulnerability by sending a specially crafted HTTP/1.1 chunk-size token that includes post-digit whitespace. This incorrect parsing of the chunk size can lead to HTTP request smuggling. This allows an attacker to bypass security controls or access unauthorized resources in proxy/backend deployments. | ||||
| CVE-2026-94001 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-22 | 6.5 Medium |
| A flaw was found in the Admin REST API of Keycloak, an open-source identity and access management solution. The endpoint used for deleting user credentials does not correctly check for fine-grained reset-password permissions. This allows a delegated administrator, who should be restricted from resetting passwords, to delete a user's password credentials, resulting in the user being unable to log in. | ||||
| CVE-2026-93579 | 2 Io.netty, Redhat | 20 Netty-codec-http2, Amq Broker, Apicurio Registry and 17 more | 2026-09-22 | 6.5 Medium |
| A flaw was found in Netty's HTTP/2 stack. This vulnerability allows a remote attacker to inject prohibited characters, such as NUL, Line Feed, and Carriage Return, into HTTP/2 header field values due to insufficient validation. When these values cross an HTTP/2 to HTTP/1.1 translation boundary, they can be exploited for request smuggling, header injection, or response splitting. This could lead to unauthorized access, data manipulation, or other security bypasses. | ||||
| CVE-2026-93565 | 2 Red Hat, Redhat | 21 Red Hat Amq Broker 7, Amq Broker, Amq Clients and 18 more | 2026-09-22 | 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 | 18 Amq Broker, Amq Broker 7, Apicurio Registry and 15 more | 2026-09-22 | 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-2026-93999 | 1 Redhat | 4 Build Keycloak, Build Of Keycloak, Red Hat Single Sign On and 1 more | 2026-09-22 | 4.2 Medium |
| A flaw was found in the OIDC protocol implementation of Keycloak, an open-source identity and access management solution. The issue occurs during the token refresh process when the server restores requested audiences from stored client IDs. Keycloak fails to verify if the target audience client is still enabled before issuing a new access token. This allows an application with an existing refresh token to continue obtaining valid access tokens for a disabled client, potentially bypassing administrative access controls for resource servers that rely on offline JWT validation. | ||||
| CVE-2026-14180 | 1 Redhat | 14 Apache Camel Hawtio, Build Of Apache Camel - Hawtio, Build Of Apache Camel For Spring Boot and 11 more | 2026-09-22 | 5.3 Medium |
| A flaw was found in the ChunkReader component of the Undertow HTTP server, which is used by WildFly and JBoss EAP to handle chunked transfer encoding. The issue occurs because the parser uses a single internal variable to store both the remaining chunk size and state flags. By sending a specially crafted request with an extremely large chunk size, an attacker can cause these values to overlap, tricking the parser into thinking a request has finished prematurely. This can allow a second, "smuggled" request to be processed out of sync, potentially bypassing security controls. | ||||
