CVE-2026-93565

Io.netty/netty-codec-http: netty rtspdecoder method-token smuggling via trailing control byte

Published: Sep 18, 2026Updated: Sep 22, 2026 Sources: CVE List NVDCWE-1035

7.5HIGH

Description

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.
