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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-444"],"vendors":[],"products":[],"references":[{"url":"https://github.com/miyagawa/Starman/commit/91c47c529cd1e100f938486896ea9083ec3ec7bf.patch","tags":[]},{"url":"https://metacpan.org/release/MIYAGAWA/Starman-0.4019/changes","tags":[]}],"exploitRefs":[{"url":"https://github.com/miyagawa/Starman/commit/91c47c529cd1e100f938486896ea9083ec3ec7bf.patch","tags":[]}],"hasPoc":true,"ai":null}
