العربيةPass role to Glue
Can create a Glue dev endpoint with a role and run an interactive session as it.
Grants escalation only in combination. All of these are needed together:
iam:PassRoleglue:CreateDevEndpointiam:PassRole can create a Glue dev endpoint with a role and run an interactive session as it, but only when it is held together with glue:CreateDevEndpoint. Held together they reach administrator access.
Why it is dangerous
A principal holds iam:PassRole on the target role plus glue:CreateDevEndpoint, so it can create a Glue development endpoint assigned the target role as its role and obtain an interactive session that runs with the target role's permissions. Because the target role trusts glue.amazonaws.com the pass is accepted; the privileged role yields run-as-role code execution and credential theft.
In MITRE ATT&CK terms this maps to T1648, Serverless Execution, under the privilege escalation tactic. AWS records it in CloudTrail as CreateDevEndpoint. The call shows up in CloudTrail but blends into normal administration, so it needs a rule to stand out.

Privilege Escalation
A control that would remove it: Remove iam:PassRole for this role or scope it with iam:PassedToService.
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 iam:PassRole allow?
Can create a Glue dev endpoint with a role and run an interactive session as it.
What else is needed for iam:PassRole to be dangerous?
It becomes an escalation only when held together with glue:CreateDevEndpoint. On its own it is not enough, which is what makes the combination easy to miss.
How is pass role to Glue detected?
Watch for CreateDevEndpoint 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?
A control that would remove it is: Remove iam:PassRole for this role or scope it with iam:PassedToService. Whether to apply it depends on how the permission is used in your account, so it is a business decision rather than an automatic fix.
Which MITRE ATT&CK technique is this?
T1648, Serverless Execution, under the privilege escalation tactic.
