Executive brief
Amazon Bedrock is a managed service that enterprises use to build and deploy generative AI applications and agents. This vulnerability in the AgentCore component results from insufficient input validation, which could allow attackers to exploit the service and potentially compromise its functionality or security properties. The exact impact depends on how the flaw can be leveraged, but insufficient input validation in an AI agent framework could enable injection attacks, unauthorized access, or service disruption.
Technical details
The vulnerability exists in the Amazon Bedrock AgentCore harness and is classified as insufficient input validation (CWE-20). The root cause involves inadequate validation of inputs processed by the AgentCore component, which is responsible for orchestrating agent behavior within the Bedrock platform. An attacker could exploit this by supplying malformed or malicious input to the AgentCore harness, potentially leading to injection attacks, logic bypass, or other undefined behavior. The vulnerability is not known to be actively exploited in the wild. Patch status and remediation details are available through the AWS security bulletin.
