CVE-2026-30914
Published: 13 March 2026
Summary
CVE-2026-30914 is a medium-severity Path Traversal (CWE-22) vulnerability in Sftpgo Project Sftpgo. Its CVSS base score is 5.3 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 40.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 AC-25 (Reference Monitor) and AC-3 (Access Enforcement).
Deeper analysis
CVE-2026-30914 is a path normalization discrepancy in SFTPGo, an open-source, event-driven file transfer solution, affecting versions prior to 2.7.1. The issue arises between protocol handlers and the internal Virtual Filesystem routing, leading to an authorization bypass classified as CWE-22 (Path Traversal). It carries a CVSS v3.1 base score of 8.1 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N), indicating high severity due to network accessibility, low attack complexity, and significant confidentiality and integrity impacts.
An authenticated attacker with low privileges (PR:L) can exploit this vulnerability remotely without user interaction. By crafting specific file paths, they bypass folder-level permissions or escape the boundaries of a configured Virtual Folder, potentially accessing or modifying unauthorized files.
The vulnerability is addressed in SFTPGo version 2.7.1. Additional details on the issue and mitigation are available in the GitHub security advisory at https://github.com/drakkan/sftpgo/security/advisories/GHSA-x8qh-7475-c5mp.
