How broadly exploitable is this vulnerability?

Exploitation is limited to authenticated users who can access the GraphQL API and have write permissions to at least one asset volume. Within that scope, however, a user may be able to affect assets in any other volume, including restricted ones, depending on configuration.

Does an attacker need administrative access to exploit this issue?

No. The attacker only needs a non-admin account with write access to a single asset volume and the ability to execute the `saveAsset` mutation. They do not require direct access rights to the targeted volumes.

What is the safest general fix pattern for developers?

The safest approach is to always perform authorization against the concrete resource after it has been loaded. In practice, this means: load the asset by ID, confirm its volume (and any other relevant attributes), and only then proceed if the current user has explicit rights for that specific asset and its volume.
