| 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-2026-90997 | 2 Keycloak, Redhat | 2 Keycloak, Build Keycloak | 2026-09-22 | 7.4 High |
| A flaw was found in Keycloak. When deployed in stateless mode with MySQL or MariaDB, a mismatch in row-count semantics between the database driver and Keycloak's application logic allows an attacker to bypass replay protection. This vulnerability enables an attacker who intercepts single-use security artifacts, such as JWT client assertions, DPoP proofs, or one-time password (TOTP) codes, to replay them. Successful exploitation grants unauthorized access to the token endpoint or login flow. | ||||
| 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-2026-10832 | 1 Redhat | 23 Apache Camel Hawtio, Build Keycloak, Build Of Apache Camel - Hawtio and 20 more | 2026-09-22 | 5.9 Medium |
| A flaw was found in the DERDecoder class within wildfly-elytron-asn1. A remote attacker can exploit this resource exhaustion vulnerability by sending a specially crafted DER (Distinguished Encoding Rules) payload. The decoder attempts to allocate excessive memory based on an inflated length value without proper validation, leading to Java Virtual Machine (JVM) memory exhaustion. This results in a remote Denial of Service (DoS) for services that process untrusted DER/ASN.1 input, including SASL (Simple Authentication and Security Layer) authentication mechanisms and X.500 certificate principal parsing paths. | ||||
| CVE-2026-87743 | 2 Red Hat, Redhat | 19 Red Hat Openshift Ai (rhoai), Apicurio Registry, Build Keycloak and 16 more | 2026-09-22 | 7.5 High |
| A flaw was found in Quarkus HTTP security. An unauthenticated attacker can exploit a discrepancy in how paths are normalized between the security matcher and HTTP request dispatchers. This allows the attacker to craft a URL that the security matcher considers public, but which is then routed to a protected endpoint, leading to an authorization bypass and potential unauthorized access to sensitive information. | ||||
| CVE-2023-6563 | 1 Redhat | 9 Build Keycloak, Enterprise Linux, Keycloak and 6 more | 2026-09-22 | 7.7 High |
| An unconstrained memory consumption vulnerability was discovered in Keycloak. It can be triggered in environments which have millions of offline tokens (> 500,000 users with each having at least 2 saved sessions). If an attacker creates two or more user sessions and then open the "consents" tab of the admin User Interface, the UI attempts to load a huge number of offline client sessions leading to excessive memory and CPU consumption which could potentially crash the entire system. | ||||
| CVE-2026-94215 | 1 Redhat | 2 Build Keycloak, Red Hat Single Sign On | 2026-09-21 | 5.5 Medium |
| A flaw was found in the Admin REST API of Keycloak, an open-source identity and access management solution. The issue occurs because the API uses a per-request in-memory cache to resolve clients by their unique identifier without verifying if the client belongs to the realm specified in the request path. This allows an administrator with limited privileges to read or modify sensitive client configurations in the master realm by accessing them through a realm they control. Successful exploitation could lead to the exposure of client credentials or the redirection of administrative login attempts to malicious sites. | ||||
| CVE-2026-89059 | 1 Redhat | 22 Apicurio Registry, Build Keycloak, Build Of Apache Camel For Quarkus and 19 more | 2026-09-21 | 7.5 High |
| A flaw was found in RESTEasy's IIOImageProvider, which decodes attacker-supplied image request bodies without enforcing any limit on the declared image dimensions or pixel count. A remote, unauthenticated attacker can send a small crafted image declaring enormous dimensions to trigger a very large memory allocation, exhausting the JVM heap and resulting in a denial of service. | ||||
