{"cve":"CVE-2026-48480","nvd":{"published":"2026-06-04T19:16:30.253","modified":"2026-07-22T20:10:00.127","status":"Deferred","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↔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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U","score":6.6},"cvss_v3":null,"cwes":["CWE-325"],"references":["https://github.com/netty/netty-incubator-codec-ohttp/commit/28f977f293591a4e837bd59ceb441f9f70349915","https://github.com/netty/netty-incubator-codec-ohttp/security/advisories/GHSA-r6fj-869h-4f6q"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:37:48.043517290+00:00"},"epss":{"cve":"CVE-2026-48480","score":0.00167,"percentile":0.0595,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-r6fj-869h-4f6q","url":"https://osv.dev/vulnerability/GHSA-r6fj-869h-4f6q","summary":"OHttpVersionChunkDraft: Missing Final-Chunk Enforcement Leads to Undetected Stream Truncation","modified":"2026-06-23T22:11:28.235730Z","packages":[{"ecosystem":"Maven","name":"io.netty.incubator:netty-incubator-codec-ohttp","purl":"pkg:maven/io.netty.incubator/netty-incubator-codec-ohttp","ranges":["<0.0.22.Final"],"fixed":["0.0.22.Final"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
