{"id":"CVE-2026-30915","aliases":["GHSA-m83q-5wr4-4gfp","GO-2026-4697"],"url":"https://o3.security/vulnerability/CVE-2026-30915","summary":"SFTPGo improperly sanitizes placeholders in group home directories/key prefixes","details":"SFTPGo is an open source, event-driven file transfer solution. SFTPGo versions before v2.7.1 contain an input validation issue in the handling of dynamic group paths, for example, home directories or key prefixes. When a group is configured with a dynamic home directory or key prefix using placeholders like %username%, the value replacing the placeholder is not strictly sanitized against relative path components. Consequently, if a user is created with a specially crafted username the resulting path may resolve to a parent directory instead of the intended sub-directory. This issue is fixed in version v2.7.1","published":"2026-03-13T19:04:36.856Z","modified":"2026-08-12T03:51:47.298380762Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/drakkan/sftpgo/v2","fixedVersion":"2.7.1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30915.json"},{"type":"ADVISORY","url":"https://github.com/drakkan/sftpgo/security/advisories/GHSA-m83q-5wr4-4gfp"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30915"},{"type":"PACKAGE","url":"https://github.com/drakkan/sftpgo"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2026-4697"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:47.298380762Z"}}
