{"id":"GHSA-wwv9-g5x4-966q","summary":"SFTPGo source-side file-pattern filter bypass during copy operations","details":"### Summary\n\nFile pattern filters (`denied_patterns` / `allowed_patterns`) were evaluated on the destination of a copy only. A user holding the copy permission could copy a file denied by the filters to a permitted name and then read it. A recursive directory copy reproduced the contents of a restricted directory under a path where the filters do not deny them, and the hide policy was affected in the same way: a file reported as missing by stat and by directory listings could still be copied.\n\n### Details\n\nAn authenticated user can read the contents of files that the file pattern filters are configured to deny them. Nothing else is bypassed: the home directory, the virtual folder layout and the per-directory permissions are all still enforced, and both ends of the copy are paths the account can already reach. No access to other accounts and no administrative capability.","aliases":["CVE-2026-103028"],"modified":"2026-10-15T20:30:03.592464545Z","published":"2026-10-15T20:22:10Z","database_specific":{"github_reviewed_at":"2026-10-15T20:22:10Z","nvd_published_at":"2026-10-13T15:17:30Z","cwe_ids":["CWE-863"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-wwv9-g5x4-966q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-103028"},{"type":"WEB","url":"https://github.com/drakkan/sftpgo/commit/dc8886bc079094b4ac2338df683f358b7676b5eb"},{"type":"PACKAGE","url":"https://github.com/drakkan/sftpgo"},{"type":"WEB","url":"https://github.com/drakkan/sftpgo/releases/tag/v2.7.6"}],"affected":[{"package":{"name":"github.com/drakkan/sftpgo/v2","ecosystem":"Go","purl":"pkg:golang/github.com/drakkan/sftpgo/v2"},"ranges":[{"type":"SEMVER","events":[{"introduced":"2.5.0"},{"fixed":"2.7.6"}]}],"database_specific":{"last_known_affected_version_range":"\u003c= 2.7.5","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/10/GHSA-wwv9-g5x4-966q/GHSA-wwv9-g5x4-966q.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
