Description

Flarum Extension Manager 2.0.0-beta.1 before 2.0.0-beta.8 lacks authentication and admin checks on the TaskResource index endpoint, allowing unauthenticated information disclosure. Remote attackers can send GET requests to /api/extension-manager-tasks to read task output revealing filesystem paths, installed extensions, versions, and PHP version.
