### 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 doesnt 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.
