Bytewhisper code ql testing

[DrJekels]

Thank you for contributing to LangChain!

• CodeQL with Chat Sanitization/Validation Tool with Prompt Escape/Injection Documentation: "core:sanitize.py; how-to:Prevent-Prompt-Injection/Escape; infra:CodeQL"

• Bytewhisper to add security testing to Langchain core:

  • Tested CodeQL in Actions and pushing the action to master for use in CI/CD testing for langchain-core. Built a tool for sanitizing/validating user supplied inputs for safe characters; with a tool to allow for user safe delimiters. Add documentation in the how-to section on preventing prompt injection/escape as a guide to help with building secure apps.
  • CodeQL action will need to be modified to work with desired branches.

CodSpeed Walltime Performance Report

Merging #31544 will not alter performance

_{Comparing DrJekels:Bytewhisper-CodeQL-Testing (36f59cd) with master (9ce9742)}

⚠️ Unknown Walltime execution environment detected

Using the Walltime instrument on standard Hosted Runners will lead to inconsistent data.

For the most accurate results, we recommend using CodSpeed Macro Runners: bare-metal machines fine-tuned for performance measurement consistency.

Summary

✅ 13 untouched benchmarks
