When a read ends in the last bytes of a chunk, add() takes the chunk short and parses the leftover data as the next chunk-size line.\n\nA remote attacker can make a chunked body never complete, hanging a server that reads until the body is done, and may make it complete early, leaving the remaining bytes to be read as the next request.","categories":["Unclassified"],"product":"","vendor":"","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116531","source_modified_at":"2026-10-28T17:16:42.065Z","fetched_at":"2026-10-28T20:58:01.013507Z","product":null,"vendor":null,"versions":[{"lessThan":"1.23_01","status":"affected","version":"0","versionType":"custom"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116531","source_modified_at":"2026-10-28T17:16:42.065Z","fetched_at":"2026-10-28T20:58:01.013507Z","package":{"name":null,"ecosystem":null},"version":"1.23_01","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T17:16:42.065Z","modified_at":"2026-10-28T17:16:42.065Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116531","fetched_at":"2026-10-28T20:58:01.013507Z","source_modified_at":"2026-10-28T17:16:42.065Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/libwww-perl/HTTP-Body/commit/5869dde9fe6d13f189a435b6583fd63fcc18677a.patch","tags":["patch"]},{"source":"CVE List","url":"https://metacpan.org/release/GETTY/HTTP-Body-1.24/changes","tags":["release-notes"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T17:16:42.065Z","content_hash":"dff18878157901a3011ba62b856c15bed9a8c22f4cbf6f696608f6047c4dfcd5"}}
