FKIE_CVE-2026-35053
Vulnerability from fkie_nvd - Published: 2026-04-02 20:16 - Updated: 2026-07-24 21:10
Severity
Summary
OneUptime is an open-source monitoring and observability platform. Prior to version 10.0.42, the Worker service's ManualAPI exposes workflow execution endpoints (GET /workflow/manual/run/:workflowId and POST /workflow/manual/run/:workflowId) without any authentication middleware. An attacker who can obtain or guess a workflow ID can trigger arbitrary workflow execution with attacker-controlled input data, enabling JavaScript code execution, notification abuse, and data manipulation. This issue has been patched in version 10.0.42.

Antes de la versi\u00f3n 10.0.42, la ManualAPI del servicio Worker expone puntos finales de ejecuci\u00f3n de flujos de trabajo (GET /workflow/manual/run/:workflowId y POST /workflow/manual/run/:workflowId) sin ning\u00fan middleware de autenticaci\u00f3n. Un atacante que puede obtener o adivinar un ID de flujo de trabajo puede desencadenar la ejecuci\u00f3n arbitraria de flujos de trabajo con datos de entrada controlados por el atacante, lo que permite la ejecuci\u00f3n de c\u00f3digo JavaScript, el abuso de notificaciones y la manipulaci\u00f3n de datos. Este problema ha sido parcheado en la versi\u00f3n 10.0.42."
