CVE-2026-35053 | THREATINT

Description

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.
