    buildalon/setup-steamcmd leaked authentication token in job output logs

    GHSA-mj96-mh85-r574

    Affected
    • GitHub Actions buildalon/setup-steamcmd < 1.1.0
    Fixed in
    1.1.0· Vendor fix available
    Issue
    Log output includes authentication token that provides full account access Details The post job action prints the contents of config/config.vdf which holds the saved authentication token and can be used to sign in on another machine. This means any public use of this action leaves authentication tokes for the associated steam accounts publicly available. Additionally, userdata/$userid$/config/localconfig.vdf contains potentially sensitive information which should not be included in public logs. PoC Use the following workflow step Impact Anyone who has used this workflow action with a steam account is affected and has had valid authentication tokens leaked in the job logs. This is particularly bad for public repositories, as anyone with a GitHub account can access the logs and view the token.

    Recommended action: Upgrade to 1.1.0 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
