GMS-2022-4260: Improper Access Control

Impact

Harbor fails to validate the user permissions to view Webhook policies including relevant credentials configured in different projects the user doesn’t have access to, resulting in malicious users being able to read Webhook policies of other users/projects. API call is

  GET /projects/{project_name_or_id}/webhook/policies/{webhook_policy_id}

By sending the below request and specifying different Webhook policy ids in the last part of the URL, the malicious user may disclose Webhook policies related to other repositories/projects.: none;">

Patches

This and similar issues are fixed in Harbor v2.5.2 and later. Please upgrade as soon as possible.

Workarounds

There are no workarounds available.
