{"id":"CVE-2026-48480","summary":"netty-incubator-codec-ohttp OHttpVersionChunkDraft's Missing Final-Chunk Enforcement Leads to Undetected Stream Truncation","details":"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.","aliases":["GHSA-r6fj-869h-4f6q"],"modified":"2026-08-07T20:53:18.996599Z","published":"2026-06-04T17:39:40.252Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-325"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48480.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/48xxx/CVE-2026-48480.json"},{"type":"ADVISORY","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":"FIX","url":"https://github.com/netty/netty-incubator-codec-ohttp/commit/28f977f293591a4e837bd59ceb441f9f70349915"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/netty/netty-incubator-codec-ohttp","events":[{"introduced":"0"},{"fixed":"28f977f293591a4e837bd59ceb441f9f70349915"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.0.22.Final"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["netty-incubator-codec-parent-ohttp-0.0.21.Final","netty-incubator-codec-parent-ohttp-0.0.20.Final","netty-incubator-codec-parent-ohttp-0.0.19.Final","netty-incubator-codec-parent-ohttp-0.0.18.Final","netty-incubator-codec-parent-ohttp-0.0.17.Final","netty-incubator-codec-parent-ohttp-0.0.16.Final","netty-incubator-codec-parent-ohttp-0.0.15.Final","netty-incubator-codec-parent-ohttp-0.0.14.Final","netty-incubator-codec-parent-ohttp-0.0.13.Final","netty-incubator-codec-parent-ohttp-0.0.12.Final","netty-incubator-codec-parent-ohttp-0.0.11.Final","netty-incubator-codec-parent-ohttp-0.0.10.Final","netty-incubator-codec-parent-ohttp-0.0.9.Final","netty-incubator-codec-parent-ohttp-0.0.8.Final","netty-incubator-codec-parent-ohttp-0.0.7.Final","netty-incubator-codec-parent-ohttp-0.0.6.Final","netty-incubator-codec-parent-ohttp-0.0.5.Final","netty-incubator-codec-parent-ohttp-0.0.4.Final","netty-incubator-codec-parent-ohttp-0.0.3.Final","netty-incubator-codec-parent-ohttp-0.0.2.Final","netty-incubator-codec-parent-ohttp-0.0.1.Final"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-48480.json","vanir_signatures_modified":"2026-08-07T20:53:18Z","vanir_signatures":[{"signature_version":"v1","source":"https://github.com/netty/netty-incubator-codec-ohttp/commit/28f977f293591a4e837bd59ceb441f9f70349915","target":{"file":"codec-ohttp/src/main/java/io/netty/incubator/codec/ohttp/OHttpVersionChunkDraft.java","function":"parse"},"deprecated":false,"digest":{"function_hash":"172681838440195430634242530865912492645","length":464},"id":"CVE-2026-48480-700c1754","signature_type":"Function"},{"deprecated":false,"digest":{"line_hashes":["210970647024931410295177236523325314805","23405354356339476106513518735652854393","35710410833280869337835572940126990288","242233450382520168894499736045170195602","86176128295672250722764126806932849931","4145526744158864901075540952181738546","266150131871301343082520767145242889303","105738737139289637700806823227011844728","200474647892198709255883345894815353391","221642661635392621042063434185764719187","46036457682425418680547798461795119723"],"threshold":0.9},"id":"CVE-2026-48480-86c8936a","signature_type":"Line","signature_version":"v1","source":"https://github.com/netty/netty-incubator-codec-ohttp/commit/28f977f293591a4e837bd59ceb441f9f70349915","target":{"file":"codec-ohttp/src/main/java/io/netty/incubator/codec/ohttp/OHttpVersionChunkDraft.java"}}]}}],"schema_version":"1.8.0","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"}]}
