This could allow an attacker to craft an input that can cause Content-Disposition header parsing in Rackto take an unexpected amount of time, possibly resulting in a denial ofservice attack vector. This header is used typically used in multipartparsing. Any applications that parse multipart posts using Rack (virtuallyall Rails applications) are impacted.","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:N/A:H","score":7.5},"cwes":["CWE-1333","CWE-400"],"references":["https://discuss.rubyonrails.org/t/cve-2022-44571-possible-denial-of-service-vulnerability-in-rack-content-disposition-parsing/82126","https://security.netapp.com/advisory/ntap-20231208-0013/","https://www.debian.org/security/2023/dsa-5530","https://discuss.rubyonrails.org/t/cve-2022-44571-possible-denial-of-service-vulnerability-in-rack-content-disposition-parsing/82126","https://security.netapp.com/advisory/ntap-20231208-0013/"],"products":["rack:rack"],"source":"nvd","synced_at":"2026-10-19T21:37:38.595364862+00:00"},"epss":{"cve":"CVE-2022-44571","score":0.01503,"percentile":0.74323,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-93pm-5p5f-3ghx","url":"https://osv.dev/vulnerability/GHSA-93pm-5p5f-3ghx","summary":"Denial of Service Vulnerability in Rack Content-Disposition parsing","modified":"2024-12-01T05:24:17.798143Z","packages":[{"ecosystem":"RubyGems","name":"rack","purl":"pkg:gem/rack","ranges":[">=2.0.0 <2.0.9.2"],"fixed":["2.0.9.2"]},{"ecosystem":"RubyGems","name":"rack","purl":"pkg:gem/rack","ranges":[">=2.1.0 <2.1.4.2"],"fixed":["2.1.4.2"]},{"ecosystem":"RubyGems","name":"rack","purl":"pkg:gem/rack","ranges":[">=2.2.0 <2.2.6.1"],"fixed":["2.2.6.1"]},{"ecosystem":"RubyGems","name":"rack","purl":"pkg:gem/rack","ranges":[">=3.0.0.0 <3.0.4.1"],"fixed":["3.0.4.1"]}]}],"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).
