CVE-2026-30915: Sftpgo Project Sftpgo

Medium severity, CVSS 4.3. EPSS: 0.4% chance of exploitation in the next 30 days.

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

Affected products

• Sftpgo Project Sftpgo: from 2.3.0, before 2.7.1 (fixed in 2.7.1)
