CVE-2026-78379: Amazon Strands-Agents-Tools

High severity, CVSS 8.1. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Amazon Strands-Agents-Tools: before 0.8.5 (fixed in 0.8.5)
