{"id":"CVE-2025-27553","details":"Relative Path Traversal vulnerability in Apache Commons VFS before 2.10.0.\n\nThe FileObject API in Commons VFS has a 'resolveFile' method that\ntakes a 'scope' parameter. Specifying 'NameScope.DESCENDENT' promises that \"an exception is thrown if the resolved file is not a descendent of\nthe base file\". However, when the path contains encoded \"..\"\ncharacters (for example, \"%2E%2E/bar.txt\"), it might return file objects that are not\na descendent of the base file, without throwing an exception.\nThis issue affects Apache Commons VFS: before 2.10.0.\n\nUsers are recommended to upgrade to version 2.10.0, which fixes the issue.","aliases":["GHSA-9q4x-fr4m-jp86"],"modified":"2026-03-15T22:20:44.311131Z","published":"2025-03-23T15:15:13.377Z","related":["SUSE-SU-2025:1022-1","openSUSE-SU-2025:14929-1"],"references":[{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/04/msg00006.html"},{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2025/03/23/1"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/cnzqowyw9r2pl263cylmxhnvh41hyjcb"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"fixed":"2.10.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2025-27553.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"}]}
