{"id":"DEBIAN-CVE-2026-49342","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.","modified":"2026-09-14T17:03:43.948778691Z","published":"2026-06-19T20:16:18.377Z","upstream":["CVE-2026-49342"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-49342"}],"affected":[{"package":{"name":"yard","ecosystem":"Debian:12","purl":"pkg:deb/debian/yard?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.28-2","0.9.28-2+deb12u1","0.9.28-2+deb12u2","0.9.34-1","0.9.35-1","0.9.36-1","0.9.37-1","0.9.38-1","0.9.39-1","0.9.44-1","0.9.45-1","1.17.patch1-5","2.2-3","2.2-4","2.2-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49342.json"}},{"package":{"name":"yard","ecosystem":"Debian:13","purl":"pkg:deb/debian/yard?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.9.37-1","0.9.38-1","0.9.39-1","0.9.44-1","0.9.45-1","1.17.patch1-5","2.2-3","2.2-4","2.2-5"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49342.json"}},{"package":{"name":"yard","ecosystem":"Debian:14","purl":"pkg:deb/debian/yard?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.44-1"}]}],"versions":["0.9.37-1","0.9.38-1","0.9.39-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-49342.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
