This vulnerability arises from the failure to remove the Authorization header when redirecting across domains. The exposure of the Authorization header to unauthorized actors could potentially allow for account hijacking.","cvss_v4":null,"cvss_v3":{"version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-200"],"references":["https://github.com/scrapy/scrapy/commit/5bcb8fd5019c72d05c4a96da78a7fcb6ecb55b75","https://huntr.com/bounties/49974321-2718-43e3-a152-62b16eed72a9","https://github.com/scrapy/scrapy/commit/5bcb8fd5019c72d05c4a96da78a7fcb6ecb55b75","https://huntr.com/bounties/49974321-2718-43e3-a152-62b16eed72a9"],"products":["scrapy:scrapy"],"source":"nvd","synced_at":"2026-10-19T21:48:32.179249784+00:00"},"epss":{"cve":"CVE-2024-3574","score":0.00648,"percentile":0.51062,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-cw9j-q3vf-hrrv","url":"https://osv.dev/vulnerability/GHSA-cw9j-q3vf-hrrv","summary":"Scrapy authorization header leakage on cross-domain redirect","modified":"2026-07-07T17:56:22.401006725Z","packages":[{"ecosystem":"PyPI","name":"scrapy","purl":"pkg:pypi/scrapy","ranges":[">=2 <2.11.1"],"fixed":["2.11.1"]},{"ecosystem":"PyPI","name":"scrapy","purl":"pkg:pypi/scrapy","ranges":["<1.8.4"],"fixed":["1.8.4"]}]},{"id":"PYSEC-2026-1908","url":"https://osv.dev/vulnerability/PYSEC-2026-1908","summary":"Scrapy authorization header leakage on cross-domain redirect","modified":"2026-07-07T17:47:52.911185651Z","packages":[{"ecosystem":"PyPI","name":"scrapy","purl":"pkg:pypi/scrapy","ranges":["<1.8.4",">=2 <2.11.1"],"fixed":["1.8.4","2.11.1"]}]}],"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).
