{"id":"CVE-2024-26141","aliases":["GHSA-xj5v-6v4g-jfw6"],"url":"https://o3.security/vulnerability/CVE-2024-26141","summary":"Possible DoS Vulnerability with Range Header in Rack","details":"Rack is a modular Ruby web server interface. Carefully crafted Range headers can cause a server to respond with an unexpectedly large response. Responding with such large responses could lead to a denial of service issue. Vulnerable applications will use the `Rack::File` middleware or the `Rack::Utils.byte_ranges` methods (this includes Rails applications). The vulnerability is fixed in 3.0.9.1 and 2.2.8.1.","published":"2024-02-28T23:28:10.503Z","modified":"2026-07-15T01:48:58.044351531Z","cvss":{"score":5.8,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"RubyGems","name":"rack","fixedVersion":"3.0.9.1"},{"ecosystem":"RubyGems","name":"rack","fixedVersion":"2.2.8.1"}],"fix":{"url":"https://github.com/rack/rack/commit/4849132bef471adb21131980df745f4bb84de2d9","label":"rack/rack@4849132"},"references":[{"type":"WEB","url":"https://discuss.rubyonrails.org/t/possible-dos-vulnerability-with-range-header-in-rack/84944"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2024/04/msg00022.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/26xxx/CVE-2024-26141.json"},{"type":"ADVISORY","url":"https://github.com/rack/rack/security/advisories/GHSA-xj5v-6v4g-jfw6"},{"type":"ADVISORY","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/rack/CVE-2024-26141.yml"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26141"},{"type":"ADVISORY","url":"https://security.netapp.com/advisory/ntap-20240510-0007/"},{"type":"FIX","url":"https://github.com/rack/rack/commit/4849132bef471adb21131980df745f4bb84de2d9"},{"type":"FIX","url":"https://github.com/rack/rack/commit/62457686b26d33a15a254c7768c2076e8e02b48b"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:48:58.044351531Z"}}
