An attacker can exploit this by injecting escape sequences (such as newline characters) into the header, resulting in log injection.\n\n## Impact\n\nThis vulnerability can distort log files, obscure attack traces, and complicate security auditing.\n\n## Mitigation\n\n- Update to the latest version of Rack, or\n- Remove usage of `Rack::Sendfile`.","affected":[{"package":{"name":"rack","ecosystem":"RubyGems","purl":"pkg:gem/rack"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.12"}]}],"versions":["0.1.0","0.2.0","0.3.0","0.4.0","0.9.0","0.9.1","1.0.0","1.0.1","1.1.0","1.1.1","1.1.1.pre","1.1.2","1.1.3","1.1.4","1.1.5","1.1.6","1.2.0","1.2.1","1.2.2","1.2.3","1.2.4","1.2.5","1.2.6","1.2.7","1.2.8","1.3.0","1.3.0.beta","1.3.0.beta2","1.3.1","1.3.10","1.3.2","1.3.3","1.3.4","1.3.5","1.3.6","1.3.7","1.3.8","1.3.9","1.4.0","1.4.1","1.4.2","1.4.3","1.4.4","1.4.5","1.4.6","1.4.7","1.5.0","1.5.0.beta.1","1.5.0.beta.2","1.5.1","1.5.2","1.5.3","1.5.4","1.5.5","1.6.0","1.6.0.beta","1.6.0.beta2","1.6.1","1.6.10","1.6.11","1.6.12","1.6.13","1.6.2","1.6.3","1.6.4","1.6.5","1.6.6","1.6.7","1.6.8","1.6.9","2.0.0.alpha","2.0.0.rc1","2.0.1","2.0.2","2.0.3","2.0.4","2.0.5","2.0.6","2.0.7","2.0.8","2.0.9","2.0.9.1","2.0.9.2","2.0.9.3","2.0.9.4","2.1.0","2.1.1","2.1.2","2.1.3","2.1.4","2.1.4.1","2.1.4.2","2.1.4.3","2.1.4.4","2.2.0","2.2.1","2.2.10","2.2.11","2.2.2","2.2.3","2.2.3.1","2.2.4","2.2.5","2.2.6","2.2.6.1","2.2.6.2","2.2.6.3","2.2.6.4","2.2.7","2.2.8","2.2.8.1","2.2.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-8cgq-6mh2-7j6v/GHSA-8cgq-6mh2-7j6v.json"}},{"package":{"name":"rack","ecosystem":"RubyGems","purl":"pkg:gem/rack"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.0"},{"fixed":"3.0.13"}]}],"versions":["3.0.0","3.0.1","3.0.10","3.0.11","3.0.12","3.0.2","3.0.3","3.0.4","3.0.4.1","3.0.4.2","3.0.5","3.0.6","3.0.6.1","3.0.7","3.0.8","3.0.9","3.0.9.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-8cgq-6mh2-7j6v/GHSA-8cgq-6mh2-7j6v.json"}},{"package":{"name":"rack","ecosystem":"RubyGems","purl":"pkg:gem/rack"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.11"}]}],"versions":["3.1.0","3.1.1","3.1.10","3.1.2","3.1.3","3.1.4","3.1.5","3.1.6","3.1.7","3.1.8","3.1.9"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/03/GHSA-8cgq-6mh2-7j6v/GHSA-8cgq-6mh2-7j6v.json"}}],"references":[{"type":"WEB","url":"https://github.com/rack/rack/security/advisories/GHSA-8cgq-6mh2-7j6v"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-27111"},{"type":"WEB","url":"https://github.com/rack/rack/commit/803aa221e8302719715e224f4476e438f2531a53"},{"type":"WEB","url":"https://github.com/rack/rack/commit/aeac570bb8080ca7b53b7f2e2f67498be7ebd30b"},{"type":"WEB","url":"https://github.com/rack/rack/commit/b13bc6bfc7506aca3478dc5ac1c2ec6fc53f82a3"},{"type":"PACKAGE","url":"https://github.com/rack/rack"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/rack/CVE-2025-27111.yml"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00016.html"}],"database_specific":{"cwe_ids":["CWE-117","CWE-93"],"github_reviewed":true,"github_reviewed_at":"2025-03-04T15:27:06Z","nvd_published_at":"2025-03-04T16:15:40Z","severity":"MODERATE"},"severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
