Runtime Credential Authority and Agent Memory Boundaries

The Vault Protected the Secret—Until the Agent Needed It.

Unit 42 showed how a vault-protected credential could become recoverable once resolved into an agent runtime. Identity governance must survive decryption and tool execution.

Protecting a credential at rest does not preserve its authority once the credential enters runtime context.

Unit 42 demonstrated that an indirect prompt injection against an Amazon Bedrock AgentCore Harness agent could invoke a root shell, read process memory where a service credential had been resolved into plaintext, and replay that credential externally. AWS characterized the report as informative and emphasized customer-side tool scoping and egress controls.

The continuity failure

The identity system correctly controlled retrieval of the secret, but the resulting runtime credential entered the same trust boundary as prompt-influenced execution.

The GovKM interpretation

The continuity chain should remain Identity → Purpose → Credential → Permitted Tool → Permitted Destination → Action. Decryption should not dissolve the relationship that constrains how authority may be consumed.
