Responses with a 1xx, 204 or 304 status also carry the body.\n\nOn a keep-alive or pipelined connection the client reads those bytes as the start of the next response. A front-end proxy that reuses upstream connections may then pair responses with the wrong requests.","cvss_v4":null,"cvss_v3":null,"cwes":["CWE-444"],"references":["https://github.com/miyagawa/Starman/commit/91c47c529cd1e100f938486896ea9083ec3ec7bf.patch","https://metacpan.org/release/MIYAGAWA/Starman-0.4019/changes"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:09.638852875+00:00"},"epss":null,"kev":null,"osv":[],"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).
