Summary
Prompt injection bypasses shell tool consent gate in Strands Agents Tools
Details

A prompt injection vulnerability in the shell tool in Amazon Strands Agents Tools before 0.8.0 might allow remote actors to execute arbitrary operating system commands on the agent's host via a crafted prompt that sets the non_interactive parameter to true, bypassing the human consent gate.

To remediate this issue, users should upgrade to version 0.8.0.
