Run #CodeQL queries at scale using Multi-Repository Variant Analysis (#MRVA)

https://github.com/GitHubSecurityLab/gh-mrva

I open sourced a tool to create lists of repos to run GitHub CodeQL’s Multi-Repository Variant Analysis on, using a keyword search on GitHub.

It's a Bash script you can trigger with a VSCode build task. It uses the GitHub API (via the GitHub CLI) to fill a list in the VSCode settings.

It’s a stopgap before this sort of feature makes it into the product.

You can now run a single static analysis query across thousands of repos on GitHub using CodeQL's MRVA (Multi-repo Variant Analysis).

That's great both for security research and rapidly auditing exposure to a single vuln or weakness for security teams.

It works from the CodeQL extension for VSCode, with open source public repos & private repos where CodeQL Code Scanning is enabled.
