Authenticated PII disclosure and deletion via unguarded UserController
Published Jun 29, 2026 · Updated Jun 29, 2026
Improper access control in FeehiCMS 2.1.0 and 2.1.1 allows remote authenticated users to read user PII and delete accounts. The API UserController exposes GET and DELETE actions without role or permission checks, so a regular bearer token can enumerate user records or delete any chosen account. A valid account is required; exploitation discloses usernames and email addresses or permanently removes user accounts, but no broader administrative access is demonstrated.
