CVE-2026-11393 · Code injection via improper triple-quote escaping in AgentCore CLI Bedrock Agent import

This page contains facts from public vulnerability sources. Check the original advisory before updating.

Improper neutralization of triple-quote characters during Python code generation in AgentCore CLI before v0.14.2 might allow an authenticated remote threat actor to execute arbitrary code on AWS AgentCore Runtime under the imported agent's IAM execution role and on the local environment of another user in the same AWS account, via a crafted collaborationInstruction stored on a Bedrock Agent collaborator and later processed by that other user during agent import. To remediate this issue, users should upgrade to version 0.14.2.
