CVE-2026-70594: CWE-384: Session Fixation in TryGhost Ghost
Ghost, a Node.js content management system, had a session fixation vulnerability in its Admin interface from versions 2.2.0 up to but not including 6.54.1. The issue allowed existing sessions to remain valid upon login, potentially enabling session fixation attacks if combined with another vulnerability on the same domain. This vulnerability was fixed in version 6.54.1.
AI Analysis
Technical Summary
CVE-2026-70594 describes a session fixation vulnerability (CWE-384) in the Ghost Admin interface of the Ghost CMS. Versions from 2.2.0 to before 6.54.1 did not invalidate existing sessions upon login, which could allow an attacker to fixate a session ID and hijack a user's session if another vulnerability on the same domain was exploited. The vulnerability requires user interaction and high attack complexity. It was addressed in Ghost version 6.54.1.
Potential Impact
Successful exploitation could lead to an attacker hijacking a user's session with high confidentiality and integrity impact, and low availability impact. However, exploitation requires another vulnerability on the same domain and user interaction, limiting the attack vector.
Mitigation Recommendations
Upgrade Ghost to version 6.54.1 or later, where this session fixation vulnerability has been fixed. No other specific mitigations are noted.
