Note: Verify declared build manifests and deployed runtime container environments.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Moq, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Moq v4.20.0-rc to 4.20.1 include support for [SponsorLink](https://github.com/devlooped/SponsorLink), which runs an obfuscated DLL at build time that scans local `git config` data and shares the user's hashed email address with SponsorLink's remote servers. There is no option to disable this. Moq v4.20.2 has removed this functionality.
