: If a developer requests a package that is missing locally, BaGet may automatically fetch it from an upstream mirror.
: Issues in underlying libraries, such as Microsoft.Data.SqlClient , have historically been flagged in BaGetter Docker images .
Attackers gain access to build environments, allowing them to steal secrets, environment variables, and cloud credentials. baget exploit

In some configurations, the API for pushing packages does not strictly require an API key by default, allowing any user with network access to the server to initiate an upload. Exploit-DB Full System Compromise:
