Summary

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.

Risk Assessment

Unauthenticated attackers can obtain environment information, including filesystem paths and software versions, facilitating further attacks.

Recommendation

Update Flarum Extension Manager to version 2.0.0-beta.8 or later. Until patched, consider restricting access to the /api/extension-manager-tasks endpoint.
