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.","published":"2025-03-23T15:15:13.377Z","modified":"2026-03-15T22:20:44.311131Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Maven","name":"org.apache.commons:commons-vfs2","fixedVersion":"2.10.0"}],"fix":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-03-15T22:20:44.311131Z"}}
