Description

GuardDog is a CLI tool to identify malicious PyPI packages. From 1.0.0 to 2.9.0, the programmatic remote project scanning path rewrites attacker-controlled repository URLs using a blind string replacement and then sends the caller's GitHub credentials with the resulting request. This allows an attacker who can influence the scanned repository URL to trigger SSRF and capture the GH_TOKEN used by GuardDog. This vulnerability is fixed in .
