AI Analysis
Technical Summary
CVE-2026-42147 is a Server-Side Request Forgery (SSRF) vulnerability in coollabsio's Coolify product. Before version 4.0.0-beta.474, the validation of S3 storage endpoints only checked the URL format, and the testConnection() function sent server-side requests to the configured endpoint. This allowed an authenticated user with storage management permissions to cause Coolify to request internal or metadata-service URLs, potentially exposing sensitive internal resources. The vulnerability is fixed in version 4.0.0-beta.474.
Potential Impact
An authenticated user with storage management permissions could exploit this SSRF vulnerability to make Coolify send requests to internal network resources or metadata services. This could lead to unauthorized access to sensitive internal information. The CVSS score of 4.9 indicates a medium severity impact with high confidentiality impact but no integrity or availability impact.
Mitigation Recommendations
A fix is available in Coolify version 4.0.0-beta.474. Users should upgrade to this version or later to remediate the vulnerability. Since this is a cloud service, the vendor manages remediation for the cloud-hosted service; users should verify with the vendor that their environment is updated accordingly.
