CVE-2026-78379 PUBLISHED

Consent bypass in python_repl tool via batch kwargs forwarding in Amazon Strands Agents Tools

Assigner: AMZN
Reserved: 24.08.2026 Published: 25.08.2026 Updated: 25.08.2026

Improper neutralization of input used for LLM prompting in the python_repl tool in Amazon Strands Agents Tools before 0.8.5 might allow remote actors to execute arbitrary Python code on the agent's host by bypassing the human consent gate, via a crafted prompt that forwards non_interactive_mode as a keyword argument through the batch tool. To remediate this issue, users should upgrade to version 0.8.5 or later.
