{"id":"CVE-2026-115823","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-115823","generatedAt":"2026-10-28T01:53:32.973Z","title":"Starman versions before 0.4019 for Perl send response bodies for HEAD requests, desynchronizing responses on keep-alive connections.","description":"Starman versions before 0.4019 for Perl send response bodies for HEAD requests, desynchronizing responses on keep-alive connections.\n\nFor a HEAD request Starman omits chunked framing but still writes the body returned by the application, on both the array and streaming response paths. 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.","published":"2026-10-25T17:17:02.000Z","lastModified":"2026-10-26T17:13:55.000Z","status":"Deferred","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":null,"cwe":["CWE-444"],"affected":[],"epss":{"score":0.00195,"percentile":0.09054,"date":"2026-10-26","history":[{"date":"2026-10-26","score":0.00195,"percentile":0.09054}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
