CVE-2024-56331Public exploitNetwork attack vector

Authenticated local file disclosure via unchecked browser URL

Published Dec 20, 2024 · Updated Dec 27, 2024

Path traversal in Louis Lam Uptime Kuma 1.23.0 through 1.23.15 and 2.0.0-beta.0 allows remote authenticated users to read local files. The real-browser monitor passes the submitted URL to Playwright page.goto without server-side scheme validation, so file URLs are rendered into screenshots. A logged-in account that can create a real-browser monitor is required, and disclosure is limited to files readable by the Uptime Kuma process.
