CVE-2026-26446

Description

Stomper 5e2741e is vulnerable to Denial of Service. When a broker sends data to a client whose TCP connection was already closed by the peer, the server process receives SIGPIPE and immediately terminates, resulting in a denial of service. Any unauthenticated client can trigger the crash by closing the socket at specific points.
