{"id":"GHSA-r6fj-869h-4f6q","summary":"OHttpVersionChunkDraft: Missing Final-Chunk Enforcement Leads to Undetected Stream Truncation","details":"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.","aliases":["CVE-2026-48480"],"modified":"2026-06-23T22:11:28.235730Z","published":"2026-06-23T21:59:03Z","database_specific":{"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2026-06-23T21:59:03Z","nvd_published_at":"2026-06-04T19:16:30Z","cwe_ids":["CWE-325"]},"references":[{"type":"WEB","url":"https://github.com/netty/netty-incubator-codec-ohttp/security/advisories/GHSA-r6fj-869h-4f6q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-48480"},{"type":"WEB","url":"https://github.com/netty/netty-incubator-codec-ohttp/commit/28f977f293591a4e837bd59ceb441f9f70349915"},{"type":"PACKAGE","url":"https://github.com/netty/netty-incubator-codec-ohttp"}],"affected":[{"package":{"name":"io.netty.incubator:netty-incubator-codec-ohttp","ecosystem":"Maven","purl":"pkg:maven/io.netty.incubator/netty-incubator-codec-ohttp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.0.22.Final"}]}],"versions":["0.0.1.Final","0.0.10.Final","0.0.11.Final","0.0.12.Final","0.0.13.Final","0.0.14.Final","0.0.15.Final","0.0.16.Final","0.0.17.Final","0.0.18.Final","0.0.19.Final","0.0.2.Final","0.0.20.Final","0.0.21.Final","0.0.3.Final","0.0.4.Final","0.0.5.Final","0.0.6.Final","0.0.7.Final","0.0.8.Final","0.0.9.Final"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-r6fj-869h-4f6q/GHSA-r6fj-869h-4f6q.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
