CVE-2026-64785

A flaw was found in SwiftNIO HTTP/2. This vulnerability allows a remote attacker to perform HTTP request smuggling or response splitting. The issue stems from insufficient validation of incoming HTTP/2 HEADERS frames, which are parts of an HTTP/2 request. This allows special control characters,...

io.netty/netty-codec-http2: Netty: Improper header neutralization in netty-codec-http2

A flaw was found in Netty's netty-codec-http2 component. The HTTP/2 encoder does not properly handle special characters in HTTP headers. This vulnerability allows a remote attacker to craft specific HTTP/2 requests, leading to HTTP response splitting and header injection attacks. Such attacks can...
