EchelonGraph scoreMEDIUM confidence

This medium-severity CVE scores 6.6 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 94% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

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↔gateway or relay↔client transport) can forward a prefix of a legitimate chunked-OHTTP message—cut at a non-final chunk boundary—and close the outer body cleanly, producing no decryption error and no exception in the receiving application. Version 0.0.22.Final fixes the issue.
