Summary
OneUptime is an open-source monitoring platform. Prior to version 10.0.42, the Worker service exposes workflow execution endpoints without authentication. An attacker who knows a workflow ID can execute arbitrary workflows with controlled input, enabling JavaScript code execution, notification abuse, and data manipulation.
Risk Assessment
An unauthenticated attacker can take over the platform, execute arbitrary code, and manipulate data.
Recommendation
Update OneUptime to version 10.0.42 or later.
Original NVD description (English source)
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.
