netty-incubator-codec-ohttp OHttpVersionChunkDraft’s Missing Final-Chunk Enforcement Leads to Undetected Stream Truncation_CVE-2026-48480

{
    "lastseen": "",
    "description": "The netty incubator codec.bhttp is a java language binary http parser. Prior to version 0.0.22.FInal, the codec-ohttp implementation of draft-ietf-ohai-chunked-ohttp does not verify that a cryptographically-signed final chunk was received before the outer HTTP body terminates. An on-path adversary (the OHTTP relay itself, or any MITM on the relay\u2194gateway or relay\u2194client transport) can forward a prefix of a legitimate chunked-OHTTP message\u2014cut at a non-final chunk boundary\u2014and close the outer body cleanly, producing no decryption error and no exception in the receiving application. Version 0.0.22.Final fixes the issue.",
