Analysis Summary
# Vulnerability: Critical SQL Injection in Ghost CMS
## CVE Details
- **CVE ID:** CVE-2026-26980
- **CVSS Score:** Not explicitly listed, but characterized as "Critical"
- **CWE:** CWE-89 (SQL Injection)
## Affected Systems
- **Products:** Ghost (Open-source Content Management System)
- **Versions:** Specific versions are not detailed in the report; however, the flaw was identified by Anthropic’s Project Glasswing.
- **Configurations:** Systems running the Ghost CMS without the latest security updates.
## Vulnerability Description
This vulnerability is a SQL injection flaw. It allows an attacker to interfere with the queries that an application makes to its database. Depending on the implementation, this could allow an attacker to view data they are not normally able to retrieve, modify or delete data, or in some cases, gain administrative access to the server. This specific flaw is notable as the only vulnerability out of 225 AI-discovered bugs (via Anthropic's Mythos Preview model) to be actively exploited by threat actors.
## Exploitation
- **Status:** Exploited in the wild (Confirmed)
- **Complexity:** Not specified, but generally Low to Medium for SQL injection.
- **Attack Vector:** Network (Remote)
## Impact
- **Confidentiality:** High (Potential unauthorized access to database contents, user credentials, and private posts).
- **Integrity:** High (Potential for unauthorized modification or deletion of site content).
- **Availability:** High (Potential for database corruption or service disruption).
## Remediation
### Patches
- Users should update to the latest version of Ghost CMS immediately. Check the official Ghost [GitHub repository](https://github[.]com/TryGhost/Ghost) or administrative dashboard for update prompts.
### Workarounds
- Implement a Web Application Firewall (WAF) to filter out malicious SQL syntax.
- Ensure the database user for the CMS has "least privilege" access to minimize potential damage.
## Detection
- **Indicators of Compromise:** Unusual SQL syntax in application logs; unauthorized administrative accounts created; unexpected changes to site content.
- **Detection methods and tools:** VulnCheck’s known exploited vulnerabilities index; standard vulnerability scanners; manual audit of Ghost CMS logs for `UNION SELECT` or similar injection patterns.
