Amazon Bedrock Exposes the Cost of Overprivileged Agent Runtimes

AI agents are moving from broad runtime access to tightly controlled identities, as security teams race to limit credential exposure and lateral movement.

Updated

What is this trend?

Overprivileged AI agent runtimes are becoming a security liability because prompt injection can turn tool access into credential theft and lateral movement.

  • Prompt injection can pivot agents into SSRF and expose cloud credentials.
  • Overprivileged runtimes widen blast radius across secrets and connected services.
  • Least-privilege, short-lived agent identities are replacing broad execution roles.
  • Runtime authorization and fast revocation are now core controls for agent security.

What’s the latest?

Amazon Bedrock’s exposed-credentials flaw is the clearest example this week: a chained prompt-injection attack pushed an agent tool into an SSRF request to 169.254.169.254, exposing temporary STS credentials for the agen
