Impact
Harbor fails to validate the user permissions when updating tag retention policies. API call:
PUT /retentions/{id}
By sending a request to update a tag retention policy with an id that belongs to a project
that the currently authenticated user doesn’t have access to, the attacker could modify
tag retention policies configured in other projects.
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.
