8.2 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
A flaw was found in zstd-jni. Attackers can exploit this by supplying oversized per-sample lengths to the `Zstd.trainFromBufferDirect` function, which fails to validate the samples buffer capacity. This allows for reading past buffer boundaries, leading to out-of-bounds memory access and ultimately causing the Java Virtual Machine (JVM) to terminate, resulting in a Denial of Service (DoS).
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
A flaw was found in zstd-jni. This use-after-free vulnerability occurs because streams and contexts only hold a dictionary's shared lock during the load call, allowing the dictionary to be closed while still being referenced. A remote attacker could exploit this by closing a dictionary after associating it with a stream or context. Subsequent read or write operations would then access freed native memory, leading to silent data corruption or a Java Virtual Machine (JVM) crash, resulting in a denial of service.
7.7 (High)

Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.
7.5 (High)
Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.

1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.

Affected products
Fixed
1 product, the same list as for
CVE-2026-12860
Threats
Impact
Important
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.
