{"id":"CVE-2026-22860","summary":"Rack has a Directory Traversal via Rack:Directory","details":"Rack is a modular Ruby web server interface. Prior to versions 2.2.22, 3.1.20, and 3.2.5, `Rack::Directory`’s path check used a string prefix match on the expanded path. A request like `/../root_example/` can escape the configured root if the target path starts with the root string, allowing directory listing outside the intended root. Versions 2.2.22, 3.1.20, and 3.2.5 fix the issue.","aliases":["GHSA-mxw3-3hh2-x2mh"],"modified":"2026-04-16T04:31:04.767728179Z","published":"2026-02-18T18:45:02.095Z","related":["CGA-66q9-cjf2-4g77","openSUSE-SU-2026:10286-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22860.json","cwe_ids":["CWE-22","CWE-548"],"cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/22xxx/CVE-2026-22860.json"},{"type":"ADVISORY","url":"https://github.com/rack/rack/security/advisories/GHSA-mxw3-3hh2-x2mh"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-22860"},{"type":"FIX","url":"https://github.com/rack/rack/commit/75c5745c286637a8f049a33790c71237762069e7"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rack/rack","events":[{"introduced":"0"},{"fixed":"0cc2e00b22dffc33955ef912569f01e515a406e1"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2.2.22"}]}},{"type":"GIT","repo":"https://github.com/rack/rack","events":[{"introduced":"572a42a705b423ce98ef4e81435d4f60fb0ae53d"},{"fixed":"65044344e4780d80b409f9ba27df41b6307b5ff5"}],"database_specific":{"versions":[{"introduced":"3.0.0.beta1"},{"fixed":"3.1.20"}]}},{"type":"GIT","repo":"https://github.com/rack/rack","events":[{"introduced":"b68251c03788ff39d4a4b25424df7360426e4afd"},{"fixed":"bb5f3555bd12b9065112353e829298b3b5623ceb"}],"database_specific":{"versions":[{"introduced":"3.2.0"},{"fixed":"3.2.5"}]}}],"versions":["0.1","0.2","0.3","1.0","1.3.0","1.3.0.beta","1.3.0.beta2","1.4.0","1.4.1","1.5.0","1.5.1","1.6.0.beta","2.0.0","2.0.0.alpha","2.0.0.rc1","2.0.1","2.1.0","2.2.0","2.2.3","2.2.4","3.0.0","3.0.0.beta1","3.0.0.rc1","v2.2.1","v2.2.10","v2.2.11","v2.2.12","v2.2.13","v2.2.14","v2.2.15","v2.2.16","v2.2.17","v2.2.18","v2.2.19","v2.2.2","v2.2.20","v2.2.21","v2.2.5","v2.2.6","v2.2.6.1","v2.2.6.2","v2.2.7","v2.2.8","v2.2.9","v3.1.0","v3.1.10","v3.1.11","v3.1.12","v3.1.13","v3.1.14","v3.1.15","v3.1.16","v3.1.17","v3.1.18","v3.1.19","v3.1.2","v3.1.3","v3.1.4","v3.1.5","v3.1.6","v3.1.7","v3.1.8","v3.1.9","v3.2.0","v3.2.1","v3.2.2","v3.2.3","v3.2.4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-22860.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"}]}
