Associated Vulnerability

Title: OneUptime: Path Traversal — Arbitrary File Read (No Auth) (CVE-2026-30958)
Description:OneUptime is a solution for monitoring and managing online services. Prior to 10.0.21, an unauthenticated path traversal in the /workflow/docs/:componentName endpoint allows reading arbitrary files from the server filesystem. The componentName route parameter is concatenated directly into a file path passed to res.sendFile() in orker/FeatureSet/Workflow/Index.ts with no sanitization or authentication middleware. This vulnerability is fixed in 10.0.21.

Description

OneUptime < 10.0.21 contains a path traversal caused by unsanitized componentName parameter in /workflow/docs/:componentName endpoint, letting unauthenticated attackers read arbitrary files from the server filesystem.
