{"id":"CVE-2026-49342","summary":"YARD static cache reads raw traversal paths before router sanitization","details":"YARD is a documentation generation tool for the Ruby programming language. Prior to version 0.9.44, YARD's static cache lookup reads a request path before the router's path cleanup runs. When a server is configured with a document root, a traversal path such as `/../yard-cache-secret.html` is joined against that root and can return a readable sibling `.html` file outside the intended static tree. Version 0.9.44 patches the issue.","aliases":["GHSA-pxcc-8665-phx8"],"modified":"2026-06-26T11:56:45.558302817Z","published":"2026-06-19T19:13:59.598Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-22"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49342.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/49xxx/CVE-2026-49342.json"},{"type":"ADVISORY","url":"https://github.com/lsegal/yard/security/advisories/GHSA-pxcc-8665-phx8"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-49342"},{"type":"FIX","url":"https://github.com/lsegal/yard/commit/f78c19f0dd33a407085b4ed181bb60c0aa0078b4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/lsegal/yard","events":[{"introduced":"0"},{"fixed":"6f678d088a8bdfe7b47072311f7927958c13eb4b"},{"fixed":"f78c19f0dd33a407085b4ed181bb60c0aa0078b4"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.9.44"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.9.43","v0.9.42","v0.9.41","v0.9.40","v0.9.39","v0.9.38","v0.9.37","v0.9.36","v0.9.35","v0.9.34","v0.9.33","v0.9.32","v0.9.31","v0.9.30","v0.9.29","v0.9.28","v0.9.27","v0.9.26","v0.9.25","v0.9.24","v0.9.23","v0.9.22","v0.9.21","v0.9.20","v0.9.19","v0.9.17","v0.9.16","v0.9.15","v0.9.14","v0.9.13","v0.9.12","v0.9.11","v0.9.10","v0.9.9","v0.9.8","v0.9.7","v0.9.6","v0.9.5","v0.9.4","v0.9.3","v0.9.2","v0.9.1","v0.9.0","v0.8.7.6","v0.8.7.5","v0.8.7.4","v0.8.7.3","v0.8.7.2","v0.8.7.1","v0.8.7","v0.8.6.1","v0.8.6.2","v0.8.6","v0.8.5.2","v0.8.5.1","v0.8.5","v0.8.4.1","v0.8.4","v0.8.3","v0.8.2.1","v0.8.2","v0.8.1","v0.8.0","v0.7.4","v0.7.3","v0.7.2","v0.7.1","v0.7.0","v0.6.8","v0.6.7","v0.6.6","v0.6.5","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.8","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.0","v0.2.3.2","v0.2.3.1","v0.2.3","v0.2.2"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-49342.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:L/I:N/A:N"}]}
