Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

GHSA-q8f2-hxq5-cp4h affects the Maven package io.netty.incubator:netty-incubator-codec-bhttp versions before 0.0.13.Final. BinaryHttpParser does not validate path, authority, scheme, or method values, so an attacker who can send binary HTTP data can control the requests built from it and perform injection attacks such as request smuggling and SSRF. Upgrade to 0.0.13.Final or later.
