This vulnerability has a CVSS 3.1 base score of 9.4, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
Flag Forge is a Capture The Flag (CTF) platform. Starting in version 2.0.0 and prior to version 2.3.2, the `/api/admin/badge-templates` (GET) and `/api/admin/badge-templates/create` (POST) endpoints previously allowed access without authentication or authorization. This could have enabled unauthorized users to retrieve all badge templates and sensitive metadata (createdBy, createdAt, updatedAt) and/or create arbitrary badge templates in the database. This could lead to data exposure, database pollution, or abuse of the badge system. The issue has been fixed in FlagForge v2.3.2. GET, POST, UPDATE, and DELETE endpoints now require authentication. Authorization checks ensure only admins can access and modify badge templates. No reliable workarounds are available.
Remediation
Check the references section for vendor advisories and patches from flagforge. Update flagforge to the latest patched version.
