Description
Ech0 before 4.4.3 fails to enforce scope-based authorization on nine comment panel admin endpoints, allowing access tokens with minimal scopes to perform full comment moderation operations. Attackers with a limited-scope access token can list, approve, reject, delete comments, and modify comment system settings by directly accessing the unprotected panel endpoints.
