CVE-2026-25117Public exploitNetwork attack vector

Same-origin script execution via unsandboxed workspace routes

Published Jan 29, 2026 · Updated Jan 29, 2026

Cross-site scripting in pwn.college DOJO allows remote authenticated users to run JavaScript in the platform origin through a workspace page. The /workspace/* proxy routes forward challenge author-controlled services on ports 80, 6080, or 8080 under the primary DOJO origin instead of isolating that content on a separate origin. A challenge author must serve malicious content and persuade another user to open its workspace URL, after which the script can perform any action available to that user.
