Current Behavior

If metadata of an asset that is used in another workspace the current user has no access to is changed the following error occurs: Read access denied for workspace "....": User is no Neos Administrator and has no explicit role for workspace "admin-user"

This is caused by the method Neos\Neos\Fusion\Cache\AssetChangeHandlerForCacheFlushing::registerAssetChange() that tries to flush all workspaces identified by \Neos\Neos\AssetUsage\GlobalAssetUsageService::findByFilter() but some of those may not be accessible to the current user.

Expected Behavior

A user should be able to change Asset Metadata even if this asset was used by others.

Steps To Reproduce

1. Create user editorA
2. Login
3. Insert an image
4. Create user editorB
5. Login
6. Use Media module to assign a title to the image used in step 2 > DANG

Environment

- Flow: 9.0
- Neos: 9.0 (~beta 17)
- PHP: 8.3

Anything else?

The method that causes the exception is $contentRepository->getContentGraph($workspaceName) that is called in AssetChangeHandlerForCacheFlushing::line,50 ... did not find an obvious way around that.
