CVE-2026-34170 Details
Description
Coolify is an open-source and self-hostable tool for managing servers, applications, and databases. Prior to 4.0.0-beta.471, the GithubApp api_url field is used as the base URL for server-side HTTP requests without allowlisting or private IP blocking, allowing an authenticated user to configure a GitHub App source that causes Coolify to request internal services or cloud metadata endpoints. This issue is reported as fixed in version 4.0.0-beta.471.
A server-side request forgery (SSRF) vulnerability has been identified in Coolify versions prior to 4.0.0-beta.471. The issue arises because the GitHub App 'api_url' field is used as the base URL for server-side HTTP requests without proper validation or blocking of private IP addresses. This allows an authenticated user to configure a GitHub App source that directs Coolify to internal services or cloud metadata endpoints. The vulnerability can be exploited by any authenticated user who creates or edits a GitHub App source with a malicious URL, which Coolify then fetches via its server-side API.
Users are advised to update to Coolify version 4.0.0-beta.471 or later. For those unable to update, consider implementing a custom validation rule that blocks private or reserved IP addresses in the 'api_url' field, or allowlisting known GitHub API hosts.
