{"id":"DEBIAN-CVE-2026-44837","details":"view_component is a framework for building reusable, testable, and encapsulated view components in Ruby on Rails. From 3.0.0 to 4.9.0, the system test entrypoint canonicalizes a user-controlled file path with File.realpath, then checks whether the resolved path starts with the temp directory path. This is not a safe containment check because sibling directories can share the same string prefix. This vulnerability is fixed in 4.9.0.","modified":"2026-09-14T17:03:13.769489312Z","published":"2026-05-26T21:16:38.853Z","upstream":["CVE-2026-44837"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-44837"}],"affected":[{"package":{"name":"ruby-view-component","ecosystem":"Debian:12","purl":"pkg:deb/debian/ruby-view-component?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.53.0-1","2.53.0-2","2.69.0-1","2.74.0-1","2.74.1-1","2.82.0-1","3.12.1-1","3.13.0-1","3.2.0-1","3.8.0-1","4.12.0-1","4.15.0-1","4.4.0-1","4.4.0-2","4.5.0-1","4.8.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44837.json"}},{"package":{"name":"ruby-view-component","ecosystem":"Debian:14","purl":"pkg:deb/debian/ruby-view-component?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.12.0-1"}]}],"versions":["2.53.0-1","2.53.0-2","2.69.0-1","2.74.0-1","2.74.1-1","2.82.0-1","3.12.1-1","3.13.0-1","3.2.0-1","3.8.0-1","4.4.0-1","4.4.0-2","4.5.0-1","4.8.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-44837.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:H/I:N/A:N"}]}
