CVE-2026-70592: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in TryGhost Ghost
Ghost, a Node.js content management system, contains a path traversal vulnerability in versions from 1.20.1 up to but not including 6.54.1. An administrator-level user could exploit this flaw by supplying a crafted database backup filename containing path separators, allowing remote overwriting of certain filesystem files. This vulnerability affects the integrity and availability of the system. The issue is fixed in version 6.54.1.
AI Analysis
Technical Summary
CVE-2026-70592 is a path traversal vulnerability (CWE-22) in the Ghost CMS database export endpoint. The vulnerability arises because the endpoint does not properly reject path separators in the user-supplied database backup filename. This allows an administrator-level user to overwrite arbitrary files on the filesystem remotely, potentially impacting system integrity and availability. The vulnerability affects Ghost versions >=1.20.1 and <6.54.1 and is resolved in version 6.54.1.
Potential Impact
An attacker with administrator privileges can remotely overwrite files on the filesystem by exploiting the path traversal flaw in the database export filename. This can lead to integrity issues by modifying critical files and availability issues by corrupting or deleting important data. There is no confidentiality impact reported. No known exploits in the wild have been documented.
Mitigation Recommendations
Upgrade Ghost to version 6.54.1 or later, where this vulnerability is fixed. Since the vulnerability requires administrator-level privileges, ensure that administrator accounts are tightly controlled and monitored. Patch status is confirmed fixed in 6.54.1.
