Title
Activepieces: Server-side request forgery in MCP tool validation endpoint
Summary
Activepieces is an open source AI workflow automation platform. Prior to 0.82.0, the POST /api/v1/projects/:projectId/mcp-server/validate-agent-mcp-tool endpoint makes an outbound HTTP or SSE request to a user-supplied serverUrl without URL validation or SSRF protection. An authenticated user can cause the Activepieces server to connect to internal services, cloud metadata endpoints, or arbitrary external hosts and probe network reachability from the Activepieces host. This issue is fixed in version 0.82.0.
