Risk
HighAn unrestricted escalation path, identity administration, secret reads or the power to switch off security monitoring. Read from this policy document alone: trust policies, boundaries and SCPs in your account still decide what actually succeeds. How this is assessed
- High
Can take over existing resources that run as another role
Grants every action of 3 documented escalation paths on any resource with no condition.
- bedrock-002bedrock-agentcore:StartCodeInterpreterSession + bedrock-agentcore:InvokeCodeInterpreterunrestricted
- bedrock-007bedrock-agentcore:StartBrowserSession + bedrock-agentcore:ConnectBrowserAutomationStreamunrestricted
Use with caution: List the roles attached to the functions, instances, pipelines or notebooks it can modify: the holder effectively has them too.
- Medium
Can launch resources that run as a more privileged role
Grants the actions of 4 documented escalation paths, but only on named resources or under a condition. Review that scope before trusting it.
- bedrock-001iam:PassRole + bedrock-agentcore:CreateCodeInterpreter + bedrock-agentcore:StartCodeInterpreterSession + bedrock-agentcore:InvokeCodeInterpreterscoped
- iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/*BedrockAgentCore*
- bedrock-003iam:PassRole + bedrock-agentcore:CreateAgentRuntime + bedrock-agentcore:CreateAgentRuntimeEndpoint + bedrock-agentcore:CreateWorkloadIdentity + bedrock-agentcore:InvokeAgentRuntimeCommandscoped
- iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/*BedrockAgentCore*
- bedrock-005iam:PassRole + bedrock-agentcore:CreateHarness + bedrock-agentcore:CreateAgentRuntime + bedrock-agentcore:CreateAgentRuntimeEndpoint + bedrock-agentcore:CreateWorkloadIdentity + bedrock-agentcore:GetAgentRuntime + bedrock-agentcore:GetHarness + bedrock-agentcore:InvokeAgentRuntimeCommandscoped
- iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/*BedrockAgentCore*
- bedrock-006iam:PassRole + bedrock-agentcore:CreateBrowser + bedrock-agentcore:StartBrowserSession + bedrock-agentcore:ConnectBrowserAutomationStreamscoped
- iam:PassRole: condition iam:PassedToService, on arn:aws:iam::*:role/*BedrockAgentCore*
Use with caution: Check which roles, users or policies fall inside the scope shown above. Within it the escalation works as documented, so keep privileged principals out of it.
- Medium
Full bedrock-agentcore access on every resource
Uses bedrock-agentcore:* with Resource "*" and no condition, so every action AWS adds to that service later is granted too.
bedrock-agentcore:*Use with caution: The grant grows every time the service does. For long-lived access, prefer a policy that lists the actions you actually need.
