Prior to version 23.10.0rc1, when sending multiple HTTP requests in one TCP packet, twisted.web will process the requests asynchronously without guaranteeing the response order. If one of the endpoints is controlled by an attacker, the attacker can delay the response on purpose to manipulate the response of the second request when a victim launched two requests using HTTP pipeline. Version 23.10.0rc1 contains a patch for this issue.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","score":5.3},"cwes":["CWE-444"],"references":["https://github.com/twisted/twisted/security/advisories/GHSA-xc8x-vp79-p3wm","https://github.com/twisted/twisted/security/advisories/GHSA-xc8x-vp79-p3wm","https://lists.debian.org/debian-lts-announce/2024/11/msg00028.html"],"products":["twisted:twisted"],"source":"nvd","synced_at":"2026-10-19T21:40:11.519948003+00:00"},"epss":{"cve":"CVE-2023-46137","score":0.00879,"percentile":0.59087,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xc8x-vp79-p3wm","url":"https://osv.dev/vulnerability/GHSA-xc8x-vp79-p3wm","summary":"twisted.web has disordered HTTP pipeline response","modified":"2025-11-04T17:02:09.832366Z","packages":[{"ecosystem":"PyPI","name":"twisted","purl":"pkg:pypi/twisted","ranges":["<23.10.0rc1"],"fixed":["23.10.0rc1"]}]},{"id":"PYSEC-2023-224","url":"https://osv.dev/vulnerability/PYSEC-2023-224","summary":"","modified":"2023-11-08T04:13:41.189622Z","packages":[{"ecosystem":"PyPI","name":"twisted","purl":"pkg:pypi/twisted","ranges":["<23.10.0rc1"],"fixed":["23.10.0rc1"]}]}],"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).
