How broadly exploitable is this vulnerability?

Exploitability is limited to authenticated users or systems that already have create permissions but lack update permissions; they can abuse this flaw to overwrite `latest` in affected zot versions when that tag is present.

Does an attacker need elevated or administrative access?

No. The issue can be triggered by any principal with create rights on the repository, even if they are explicitly denied update rights; no administrative privileges are required.

What is the safest general fix pattern?

The fix pattern is to align authorization decisions with the true operation semantics: any attempt to overwrite an existing tag—`latest` included—must be classified as an update and checked against update permissions, with no special-case bypasses.
