Feature Request: Add Python 3.14 support to Amazon Inspector Lambda scanning

0

AWS Lambda added support for the python3.14 managed runtime in November 2025, but Amazon Inspector still does not scan Lambda functions using this runtime — for either standard scanning (package vulnerabilities) or code scanning.

Current state:

  • Lambda standard scanning supports up to python3.13
  • Lambda code scanning supports up to python3.13
  • python3.14 functions are silently skipped by Inspector

Request: Please add python3.14 to the supported runtimes list for both Lambda standard scanning and Lambda code scanning, consistent with how previous Python versions were added.

Impact: Teams adopting python3.14 for performance improvements (notably the experimental free-threaded mode) have a gap in their security scanning coverage with no workaround short of staying on python3.13 or switching to container-based Lambda deployments.

Thank you for your feature request regarding Python 3.14 support in Amazon Inspector Lambda scanning. I understand you'd like to see this runtime added to both Lambda standard scanning and Lambda code scanning capabilities.

Based on the current documentation, Amazon Inspector Lambda standard scanning supports Python runtimes from python3.7 through python3.13. You're correct that python3.14 is not yet listed among the supported runtimes for either scan type.

For feature requests like this, the best way to submit your request is through the AWS Support Center at https://console.aws.amazon.com/support/. When submitting, I'd recommend including the details you've outlined here:

  • The specific runtime version needed (python3.14)
  • The business impact (security scanning coverage gap for teams adopting the new runtime)
  • Your use case (performance improvements, particularly the free-threaded mode)

AWS product teams actively review customer feedback and feature requests to help prioritize their roadmaps. Submitting through the official channel ensures your request reaches the appropriate team and can be tracked.

In the meantime, you're right that teams would need to either remain on python3.13 or consider alternative deployment methods if Inspector scanning coverage is a requirement for their security posture.

I appreciate you taking the time to provide this detailed feedback about the gap between Lambda runtime support and Inspector scanning capabilities.
