Short explanation

Google::Auth for Perl versions from 0.11 through 0.12 accept authorization codes from any local process because the gcloud-auth login callback does not check the OAuth state [S0]. A local attacker can submit an authorization code for their own Google account to compromise credentials [S0]. The patch status is UNKNOWN in official sources [S0].

Why does it matter?

This vulnerability allows a local attacker to cause user tools to act under the attacker's account by swapping the stored refresh token [S0].

What should be done?

  • Follow the vendor advisory [S0].

Show the technical text from the sources

Google::Auth versions from 0.11 through 0.12 for Perl accept an authorization code from any local process because the gcloud-auth login callback does not check the OAuth state. The gcloud-auth login and application-default login commands send a state parameter with the authorization request, then take the code from the first request to reach their loopback listener without comparing the returned state. A local attacker can submit an authorization code for their own Google account. The CLI exchanges it and stores the refresh token as the user's credentials, so the user's tools then act as the attacker's account.
