CVE-2026-12530: CWE-88 Improper neutralization of argument delimiters in a command ('argument injection') in AWS bedrock-agentcore
CVE-2026-12530 is a high-severity vulnerability in AWS Bedrock AgentCore Python SDK versions from 1.1.3 up to but not including 1.6.1. It involves improper neutralization of argument delimiters in the install_packages() method, which could allow a remote authenticated user to execute arbitrary commands within the Code Interpreter sandbox by crafting malicious package name arguments. AWS has addressed this issue in version 1.6.1. The vulnerability has a CVSS 4.0 base score of 8.4, indicating significant impact if exploited.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-12530) affects the install_packages() method in AWS Bedrock AgentCore Python SDK versions >=1.1.3 and <1.6.1. The issue is due to improper neutralization of argument delimiters (CWE-88), enabling remote authenticated users to perform command injection within the Code Interpreter sandbox by supplying crafted package name arguments. AWS manages this as a cloud service and has released version 1.6.1 to mitigate the issue.
Potential Impact
Successful exploitation could allow remote authenticated users to execute arbitrary commands within the Code Interpreter sandbox environment, potentially leading to unauthorized code execution and compromise of the affected system's integrity and confidentiality. The CVSS 4.0 score of 8.4 reflects high impact with network attack vector, low attack complexity, and high impact on confidentiality and integrity.
Mitigation Recommendations
AWS has released version 1.6.1 of the Bedrock AgentCore Python SDK to address this vulnerability. Users should upgrade to version 1.6.1 to mitigate the risk. Since this is a cloud service, AWS manages remediation server-side; users should verify they are using the patched version as per the AWS security bulletin (https://aws.amazon.com/security/security-bulletins/2026-044-aws/).
