Vulnerability details
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.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Session auditing enables detection of unauthorized exposure or access to sensitive information during user activities.
Architectures explicitly define requirements and mechanisms for access control to protect confidentiality, integrity, and availability.
Inventory identifies all systems holding or processing data, enabling detection of unauthorized exposure paths before exploitation.
A CIKR protection plan that explicitly addresses information security requires defining and enforcing access control policies on critical systems and resources.
Risk assessment explicitly identifies threats from unauthorized access and drives decisions to implement or strengthen access control mechanisms.
Directly requires mechanisms to restrict public users from unauthorized actions on system resources.
Directly enforces access control by prohibiting unauthorized remote activation of cameras, mics, and similar devices.
Decoys supply misleading data and log access attempts, directly detecting and deflecting unauthorized information exposure.
