CVE-2026-27796Public exploitNetwork attack vector

Unauthenticated integration metadata disclosure via publicProcedure

Published Mar 7, 2026 · Updated Mar 7, 2026

Missing authorization in Homarr before 1.54.0 allows remote attackers to read configured integration metadata through a tRPC request. The integration.all procedure in packages/api/src/router/integration/integration-router.ts uses publicProcedure and returns integrationSchema records without a session check. Any network client that can reach the dashboard can obtain integration names, service types, and internal service URLs, exposing network topology without changing data.
