CVE-2026-93568 Sep 18, 14:34 HIGH PATCH This Week

Improper handling of HTTP/2 and HTTP/3 Extended CONNECT requests in Netty-based services can downgrade them to ordinary CONNECT requests, enabling request-smuggling or desynchronization in deployments where a fronting proxy and backend interpret the downgraded request differently. The issue carries a CVSS v3.1 base score of 7.5 (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N), meaning unauthenticated remote attackers can affect integrity, though the independent assessment raises attack complexity to High and scope to Changed and limits practical impact to proxy/gateway mismatches on endpoints that accept HTTP/2 or HTTP/3 Extended CONNECT. No CISA KEV entry or public exploit code was identified at time of analysis, so priority is moderate and conditional rather than urgent.

CVE-2026-93576 Sep 18, 14:33 HIGH PATCH This Week

SMTP command injection in Netty's netty-codec-smtp allows unauthenticated remote attackers to inject arbitrary SMTP commands via CRLF sequences in the command-name field, affecting applications built on Netty such as Red Hat Build of Apache Camel for Spring Boot 4, Red Hat Fuse 7, JBoss EAP 7, and Red Hat Single Sign-On 7. This is an incomplete fix of CVE-2025-59419, requiring attacker-controlled input to reach the SMTP command name and a downstream SMTP server that acts on smuggled commands; no public exploit identified at time of analysis. Integrity impact is high, while confidentiality and availability are unaffected.

CVE-2026-93569 Sep 18, 14:27 HIGH PATCH This Week

Mismatched handling of the HTTP/1 absolute-form request authority in Red Hat build of Quarkus and other affected Red Hat middleware lets a remote, unauthenticated attacker smuggle requests across the HTTP/1-to-HTTP/2 protocol boundary, overriding the :authority pseudo-header that downstream services use for routing and authorization. The vendor CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:H/A:N = 8.2 High) rates integrity as the dominant impact (I:H) with limited confidentiality exposure (C:L) and no availability effect, consistent with a CWE-444 request-smuggling class defect. Exploitation is not confirmed actively exploited (no CISA KEV listing) and no public exploit identified at time of analysis, although real-world exploitation requires a deployment that actually translates HTTP/1 requests into HTTP/2 and a downstream component that trusts :authority for routing or authorization decisions.

The client-supplied Host header from an HTTP/1 authority-form CONNECT is copied verbatim into the HTTP/2 :authority pseudo-header, so the fronting component and the HTTP/2 backend can disagree about the routing target, yielding an integrity impact (vendor CVSS 3.1 7.5 AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N; our assessment raises the attack complexity to High and the scope to Changed because a H1→H2 CONNECT translation path and a fronting-proxy topology are required).

CVE-2026-93565 Sep 18, 14:18 HIGH PATCH This Week

Netty's codec-rtsp component silently normalizes away trailing control bytes in RTSP method tokens, so a wire request whose method token ends in a byte with code point <= 0x20 immediately before the separating space (for example PLAY\x00 or PLAY\r) is decoded as a fully successful PLAY request with decoderResult().isSuccess() == true and request.method() referencing the same cached singleton object, leaving the application layer unable to distinguish it from a clean PLAY. This is a remote, unauthenticated, low-complexity integrity flaw (CVSS 3.1 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N) affecting any product that embeds Netty and exposes an RTSP listener, including the Red Hat components named in the advisory such as AMQ Broker 7, AMQ Clients, Quarkus, Camel for Quarkus 3/Spring Boot 4, Keycloak, JBoss EAP 7/8, Single Sign-On 7, Data Grid 8, Fuse 7, Debezium 3, and Apicurio Registry 3. Real security impact is gated on a downstream disagreement: a front-end proxy, WAF, gateway, or access-control layer must parse the RTSP method differently from Netty for method/request smuggling to produce genuine integrity effects, and exposure is narrow because RTSP listeners are far less commonly internet-facing than HTTP. Exploitation status: no public exploit identified at time of analysis and no CISA KEV confirmation, though the upstream advisory itself documents a minimal wire-level reproduction at a high level.

Denial of service in Red Hat's Camel-based and Java middleware products (Red Hat Build of Apache Camel for Spring Boot 4, Red Hat Fuse 7, JBoss EAP 7, and Red Hat Single Sign-On 7): a STOMP frame that declares an oversized content-length is truncated from a 64-bit long to a 32-bit integer, yielding a wrapped/negative length that leaves the STOMP decoder unable to advance, so it loops indefinitely and burns CPU on the affected message-processing thread. The flaw is remotely reachable and unauthenticated per the assessed vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, 7.5), but exposure is strictly limited to deployments that actually enable a network-reachable STOMP listener - products without a configured STOMP endpoint are not attackable.

Unbounded heap memory consumption in Netty's HttpServerCodec (io.netty:netty-codec-http) lets a remote, unauthenticated attacker drive a denial of service by exhausting server memory. An attacker who pipelines multiple HTTP/1.1 requests on a single connection and withholds reads prevents the internal methodOverflowQueue from being drained, so memory grows without limit; the assessed CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, base 7.5) is availability-only with no confidentiality or integrity impact, and no public exploit code was identified at time of analysis. Any HTTP/1.1 server built on the default Netty codec behavior is affected, and fixes ship in Netty 4.1.138.Final and 4.2.18.Final, with corresponding patched Red Hat product builds referenced through the Red Hat advisory.

Unbounded remote-initiated stream creation in Netty's SpdySessionHandler allows an unauthenticated, network-positioned attacker to exhaust JVM heap and direct memory on any application that exposes a SPDY endpoint, producing OutOfMemoryError and a denial of service. The handler initializes localConcurrentStreams to Integer.MAX_VALUE and provides no API to change it, so no supported configuration knob reduces the exposure once SPDY is reachable; Netty 4.1.x before 4.1.138.Final and 4.2.x before 4.2.18.Final are affected, along with the Red Hat products that bundle those versions (AMQ Broker and AMQ Clients, Camel for Quarkus 3 and for Spring Boot 4, Keycloak, Quarkus, Debezium, Apicurio Registry, Data Grid, Fuse, JBoss EAP 7/8, and RH-SSO 7). Exploitation requires the target application to have explicitly wired the SPDY handler into its Netty pipeline, since SPDY is a deprecated protocol that is not enabled by default; there is no public exploit identified at time of analysis, and the CVSS vector (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, 7.5) reflects a low-complexity, availability-only denial of service with no confidentiality or integrity impact.

Memory exhaustion in Netty's SMTP client response decoder (SmtpResponseDecoder) allows an attacker who controls or can intercept the SMTP server that an application talks to, to force that application to accumulate unlimited multi-line responses until heap is exhausted. The defect is a pure availability issue (C:N/I:N/A:H, CVSS 7.5, AV:N/AC:L/PR:N/UI:N) and is reachable without authentication or user interaction on the victim side, but exploitation is conditional: the vulnerable JVM must have Netty's SMTP client codec active and must establish an SMTP session with a hostile or man-in-the-middle peer, since only server responses are parsed. Shipping products affected through bundled Netty include Red Hat JBoss Enterprise Application Platform 7, Red Hat Fuse 7, Red Hat Single Sign-On 7 and Red Hat Build of Apache Camel for Spring Boot 4; no public exploit code has been identified at time of analysis and there is no confirmed CISA KEV entry.

Heap exhaustion in Netty's Redis array aggregator, as shipped inside Red Hat products such as JBoss Enterprise Application Platform 7, Red Hat Fuse 7, Red Hat Build of Apache Camel for Spring Boot 4, and Red Hat Single Sign-On 7, lets a remote unauthenticated attacker crash the JVM by sending a tiny stream of nested RESP array headers. Because the decoder eagerly allocates an ArrayList sized to the declared array length before any child element arrives, roughly 12 KB of crafted input can reserve about 1.02 billion child slots when the default 1024-level nesting limit and default element limit are in effect; the impact is availability-only, with no data read or modified. Exploitation is limited to deployments that feed attacker-reachable, untrusted RESP/Redis-protocol traffic into the Netty codec with the default constructor; no public exploit code and no confirmed active exploitation were identified at time of analysis.

Unrestricted Java deserialization in Red Hat EAP's embedded Apache ActiveMQ Artemis broker allows authenticated JMS clients to achieve remote code execution by sending crafted ObjectMessage payloads. The flaw stems from a logical inversion in the allow-list guard: when no allow-list is configured (the default), `isTrustedType()` unconditionally returns true, rendering the entire class-filtering mechanism inoperative. Affected products include Red Hat AMQ Broker 7, JBoss EAP 7 and 8, and Red Hat builds of Apache Camel - all widely deployed in enterprise Java environments.

Jolokia's JSR-160 proxy in multiple Red Hat middleware products allows network-accessible unauthenticated attackers (per CVSS PR:N) to bypass the denylist introduced to fix CVE-2018-1000130 by supplying alternative LDAP-scheme JMX service URLs - such as ldaps:// or LDAP URLs with a non-empty host component - that are not matched by the existing regex filter. Once accepted, the Jolokia agent JVM resolves a JNDI lookup against an attacker-controlled LDAP endpoint, enabling server-side request forgery, forwarding of in-flight JMX credentials to the attacker, and - depending on JVM classpath and security-manager configuration - remote code execution. No active exploitation (CISA KEV) or public proof-of-concept has been identified at time of analysis, but the bypass of a prior known CVE fix elevates realistic risk above the AC:H score alone implies.

Certificate revocation checking in the OCSP client shipped with Red Hat Build of Apache Camel for Spring Boot 4 can be bypassed because the client does not verify the OCSP-signing Extended Key Usage (EKU) on the certificate that signs an OCSP response, allowing a revoked certificate that still chains to a trusted CA to be accepted as valid. The issue is remotely reachable without authentication or user interaction (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N, 5.9), although exploitation is conditional: the deployment must actually rely on this OCSP client for revocation checking and the attacker must already possess a revoked-but-chainable certificate. No public exploit identified at time of analysis, and this is assessed as a genuine but moderate-priority integrity flaw rather than a high-urgency issue.

A signed/unsigned type mismatch in Netty's Memcache binary protocol codec desynchronizes frame boundaries, allowing an unauthenticated, network-positioned attacker to smuggle responses across a shared or proxied memcache connection (CVSS 3.1 base 6.5, Medium). The flaw is reachable only when the Memcache binary codec is explicitly wired into a network-exposed Netty pipeline - a non-default configuration - and the affected code ships inside Red Hat Fuse 7, JBoss Enterprise Application Platform 7, Single Sign-On 7, and the Red Hat Build of Apache Camel for Spring Boot 4. No public exploit code has been identified at time of analysis, and there is no confirmation of active exploitation (not in CISA KEV); impact is limited to confidentiality and integrity (C:L/I:L) with no availability effect.

Netty's codec-rtsp component silently normalizes away trailing control bytes in RTSP method tokens, so a wire request whose method token ends in a byte with code point <= 0x20 immediately before the separating space (for example PLAY\x00 or PLAY\r) is decoded as a fully successful PLAY request with decoderResult().isSuccess() == true and request.method() referencing the same cached singleton object, leaving the application layer unable to distinguish it from a clean PLAY. This is a remote, unauthenticated, low-complexity integrity flaw (CVSS 3.1 7.5, AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N) affecting any product that embeds Netty and exposes an RTSP listener, including the Red Hat components named in the advisory such as AMQ Broker 7, AMQ Clients, Quarkus, Camel for Quarkus 3/Spring Boot 4, Keycloak, JBoss EAP 7/8, Single Sign-On 7, Data Grid 8, Fuse 7, Debezium 3, and Apicurio Registry 3. Real security impact is gated on a downstream disagreement: a front-end proxy, WAF, gateway, or access-control layer must parse the RTSP method differently from Netty for method/request smuggling to produce genuine integrity effects, and exposure is narrow because RTSP listeners are far less commonly internet-facing than HTTP.

A signed/unsigned type mismatch in Netty's Memcache binary protocol codec desynchronizes frame boundaries, allowing an unauthenticated, network-positioned attacker to smuggle responses across a shared or proxied memcache connection (CVSS 3.1 base 6.5, Medium). The flaw is reachable only when the Memcache binary codec is explicitly wired into a network-exposed Netty pipeline - a non-default configuration - and the affected code ships inside Red Hat Fuse 7, JBoss Enterprise Application Platform 7, Single Sign-On 7, and the Red Hat Build of Apache Camel for Spring Boot 4. No public exploit code has been identified at time of analysis, and there is no confirmation of active exploitation (not in CISA KEV); impact is limited to confidentiality and integrity (C:L/I:L) with no availability effect.

Undertow's HTTP response header writing path silently truncates 16-bit Unicode characters to 8-bit bytes via a narrowing cast in the `writeString()` method, enabling remote unauthenticated attackers to inject ASCII control characters or special symbols into response headers when an application passes unsanitized user-controlled input into those headers. Affected Red Hat distributions include RHEL 8/9/10, JBoss EAP 7, Red Hat Build of Apache Camel for Spring Boot 4, and Red Hat Single Sign-On 7, as reported by Red Hat via Bugzilla #2516038. No public exploit code has been identified at time of analysis, and this vulnerability is not listed in the CISA KEV catalog.

HTTP request smuggling in Undertow's ChunkReader component enables unauthenticated remote attackers to inject out-of-sync requests, bypassing upstream security controls such as authentication layers or reverse-proxy ACLs. Affected deployments include JBoss EAP 7, WildFly, Red Hat Enterprise Linux 8/9/10, Red Hat Data Grid 8, Red Hat Fuse 7, Red Hat Single Sign-On 7, and several Apache Camel-based Red Hat products. No confirmed active exploitation or public proof-of-concept has been identified at time of analysis; the CVSS 5.3 Medium score reflects limited direct impact, though real-world risk in proxy-fronted architectures is meaningfully higher than the score alone suggests.

A resource exhaustion vulnerability exists in Undertow where remote attackers can send HTTP GET requests with multipart/form-data content to trigger premature parsing and disk storage of request data, leading to Denial of Service when applications use parameter retrieval methods like getParameterMap(). The vulnerability affects multiple Red Hat products including Enterprise Linux 8, 9, and 10, JBoss Enterprise Application Platform 7 and 8, Red Hat Fuse 7, and several Apache Camel variants. An attacker with network access and no authentication can exhaust server disk resources with moderate attack complexity, causing service unavailability.
