Critical

Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:L

Name of the Vulnerable Software and Affected Versions FlagForge versions 2.0.0 through 2.3.2

Description FlagForge, a Capture The Flag (CTF) platform, had endpoints that did not require authentication or authorization. Specifically, the /api/admin/badge-templates (GET) and /api/admin/badge-templates/create (POST) endpoints allowed unauthorized access. This allowed retrieval of badge templates and sensitive metadata (createdBy, createdAt, updatedAt) and the creation of arbitrary badge templates in the database. This could lead to data exposure and database pollution. The issue affected the badge system.

Recommendations Versions prior to 2.3.2 should be updated to version 2.3.2 or later.
