Technical summary
The create_file function in app/api/mcp/route.ts is vulnerable to path traversal, allowing remote attackers to manipulate the filePath and content arguments. The product does not use versioning, making it difficult to determine affected and unaffected releases. Defenders should prioritize verifying the presence of this vulnerability in their inventory and assessing exposure, as the exploit is publicly available and remote exploitation is possible. Affected product deployments should be identified in managed environments, and owners should be assigned for follow-up.
Defensive priority
Defenders should prioritize verifying the presence of this vulnerability in their inventory and assessing exposure, as the exploit is publicly available and remote exploitation is possible.
Recommended defensive actions
- Verify the presence of this vulnerability in your inventory
- Assess exposure to remote exploitation
- Consider compensating controls or monitoring for potential exploitation attempts
- Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
- Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
- Check relevant monitoring, detection, and logs for exposed assets that need extra review.
- Track exceptions, retest remediated assets, and close the item only after evidence is documented.
