CVE-2026-93579 2 Io.netty, Redhat 23 Netty-codec-http2, Amq Broker, Apicurio Registry and 20 more 2026-11-06 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-2026-93492 2 Io.netty, Redhat 24 Netty-codec-http2, Amq Broker, Amq Broker 7 and 21 more 2026-11-06 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-2026-93567 2 Io.netty, Redhat 24 Netty-codec-http2, Amq Broker, Apache Camel Quarkus and 21 more 2026-11-06 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.
