Share RDS snapshot out
Can share an RDS snapshot out to an attacker account.
Grants escalation on its own.
rds:ModifyDBSnapshotAttributeOn its own, rds:ModifyDBSnapshotAttribute can share an RDS snapshot out to an attacker account. On a wide resource scope that alone reaches access for an outside or public principal.
Why it is dangerous
A principal can call rds:ModifyDBSnapshotAttribute on the snapshot to share a full database copy with an attacker-controlled account, exfiltration that bypasses the live DB's network and auth controls (the attacker restores the snapshot in their own account).
In MITRE ATT&CK terms this maps to T1537, Transfer Data to Cloud Account, under the exfiltration tactic. AWS records it in CloudTrail as ModifyDBSnapshotAttribute. The call shows up in CloudTrail but blends into normal administration, so it needs a rule to stand out.

Exfiltration
A control that would remove it: Restrict rds:ModifyDBSnapshotAttribute; deny restore/share changes via SCP/policy.
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.
Questions
What does rds:ModifyDBSnapshotAttribute allow?
Can share an RDS snapshot out to an attacker account.
Can rds:ModifyDBSnapshotAttribute escalate privileges on its own?
Yes. Held on a broad enough resource it reaches access for an outside or public principal with no other permission.
How is share RDS snapshot out detected?
Watch for ModifyDBSnapshotAttribute in CloudTrail. The call shows up in CloudTrail but blends into normal administration, so it needs a rule to stand out.
How do you break this path?
