العربيةPublicly shared EBS snapshot
An EBS snapshot is shared publicly (createVolumePermission: all)..
No IAM permission is needed. The exposure is in the resource's own configuration, so anyone the policy names, or everyone when it is public, can reach it.
This is a configuration exposure, not a permission. An EBS snapshot is shared publicly (createVolumePermission: all). Anyone the policy allows, or everyone when it is public, can reach it with no IAM access of their own.
Why it is dangerous
An EBS snapshot is public; anyone can create a volume from it and read a full disk copy, bypassing the live volume's controls.
In MITRE ATT&CK terms this maps to T1580, Cloud Infrastructure Discovery, under the collection tactic.
Detection
Prerequisites
None beyond holding the permission.

Collection
A control that would remove it: Remove the public createVolumePermission from the snapshot.
Whether to apply it depends on how the permission is used in your environment, so it is a business decision rather than an automatic fix. The same permission can be load-bearing in one account and pure risk in another.
Pathbreak confirms whether this path resolves in your account, ranks it against the others by how much it opens up, and uses your threat model and business context to show which paths are worth cutting.
