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":"2025-03-23T15:15:13.000Z","lastModified":"2026-06-17T09:03:47.000Z","status":"Modified","sourceIdentifier":"security@apache.org","cvss":{"version":"3.1","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"},"cwe":["CWE-23"],"affected":["apache/commons vfs"],"epss":{"score":0.01425,"percentile":0.72726,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (1.43%).
