CVE-2026-93579 2 Io.netty, Redhat 20 Netty-codec-http2, Amq Broker, Apicurio Registry and 17 more 2026-09-21 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.

A flaw was found in RESTEasy's CorsFilter, which, when configured to allow all origins ("*"), reflects the request's Origin header back in the Access-Control-Allow-Origin response together with Access-Control-Allow-Credentials: true. This permissive cross-origin policy allows a malicious website to make credentialed cross-origin requests and read authenticated responses from a victim's session, resulting in a loss of confidentiality.
CVE-2026-93494 2 Io.netty, Redhat 8 Netty-codec-http, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 5 more 2026-09-21 7.5 High
A flaw was found in Netty's StompSubframeDecoder component. A remote attacker can exploit this vulnerability by sending a specially crafted STOMP frame body without its terminating null byte. This causes the decoder to allocate a ByteBuf (a buffer for bytes) that is never released, leading to a permanent memory leak. Over time, this uncontrolled memory consumption can result in a Denial of Service (DoS) for the application using the affected STOMP codec.
CVE-2026-93561 2 Io.netty, Redhat 8 Netty-codec-http, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 5 more 2026-09-21 6.5 Medium
A flaw was found in io.netty/netty-codec-memcache. The Memcache binary protocol codec incorrectly reads `keyLength` and `extrasLength` as signed Java types instead of unsigned, as specified by the protocol. A malicious Memcache server can exploit this type mismatch by sending a specially crafted response. This can lead to frame desynchronization and response smuggling, where one client's data may be inadvertently exposed to another client's response stream in proxy or cache environments.
CVE-2026-93575 2 Io.netty, Redhat 9 Netty-codec-http, Amq Broker, Build Of Apache Camel For Spring Boot and 6 more 2026-09-21 7.5 High
A flaw was found in Netty's MqttDecoder. An unauthenticated remote attacker can exploit this vulnerability by sending a specially crafted MQTT CONNECT packet.

CVE-2026-93578 2 Io.netty, Redhat 3 Netty-codec-http, Build Of Apache Camel For Spring Boot, Camel Spring Boot 2026-09-21 5.9 Medium
A flaw was found in Netty's Online Certificate Status Protocol (OCSP) Client. The client fails to verify the 'id-kp-OCSPSigning' Extended Key Usage (EKU) in OCSP responder certificates. A remote attacker, holding any valid certificate issued by the same Certificate Authority (CA), can exploit this by forging 'GOOD' OCSP responses for revoked certificates. This bypasses certificate revocation checks, allowing applications using Netty's OCSP Client to accept certificates that should have been revoked, leading to an authorization bypass.
CVE-2026-93563 2 Io.netty, Redhat 8 Netty-codec-http, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 5 more 2026-09-21 7.5 High
A flaw was found in Netty's `SmtpResponseDecoder` component. A remote attacker, acting as a malicious or man-in-the-middle (MITM) SMTP server, could exploit this by sending a specially crafted, unbounded multi-line SMTP response without a terminator. This vulnerability leads to unbounded memory accumulation within the client's Java Virtual Machine (JVM) heap, causing an `OutOfMemoryError` and a denial of service (DoS) due to a process crash.

CVE-2026-93492 2 Io.netty, Redhat 21 Netty-codec-http2, Amq Broker, Amq Broker 7 and 18 more 2026-09-21 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-2026-93560 2 Io.netty, Redhat 8 Netty-codec-http, Build Of Apache Camel For Spring Boot, Camel Spring Boot and 5 more 2026-09-21 7.5 High
A flaw was found in the Netty STOMP codec. A remote attacker could send a specially crafted STOMP frame with a content-length header exceeding the maximum integer value. This integer truncation vulnerability could lead to an infinite decode loop, causing a Denial of Service (DoS) by exhausting memory and CPU resources.
CVE-2026-93558 2 Io.netty, Redhat 22 Netty-codec-http, Amq Broker, Amq Broker 7 and 19 more 2026-09-21 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-2026-93564 1 Redhat 18 Amq Broker, Amq Broker 7, Apicurio Registry and 15 more 2026-09-21 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-2026-93565 2 Red Hat, Redhat 21 Red Hat Amq Broker 7, Amq Broker, Amq Clients and 18 more 2026-09-21 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-2026-93566 2 Red Hat, Redhat 21 Red Hat Amq Broker 7, Amq Broker, Amq Clients and 18 more 2026-09-21 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-2026-10832 1 Redhat 23 Apache Camel Hawtio, Build Keycloak, Build Of Apache Camel - Hawtio and 20 more 2026-09-21 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-2026-93567 2 Io.netty, Redhat 20 Netty-codec-http2, Amq Broker, Apicurio Registry and 17 more 2026-09-21 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-2026-93432 1 Redhat 11 Apicurio Registry, Build Keycloak, Build Of Apache Camel For Quarkus and 8 more 2026-09-21 6.1 Medium
A flaw was found in the Quarkus Qute template engine. When the {#eval} section helper processes a sub-template, it fails to pass the parent template's content type information. This bypasses standard escaping mechanisms, allowing untrusted data to be output as raw, unescaped text. This vulnerability can lead to Cross-Site Scripting (XSS) and JSON Injection, potentially allowing a remote attacker to execute arbitrary code in a user's browser or manipulate data.
CVE-2026-93574 2 Io.netty, Redhat 21 Netty-codec-http, Amq Broker, Amq Clients and 18 more 2026-09-21 6.5 Medium
A flaw was found in Netty's `netty-codec-http` component.
