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