Affected versions of this package are vulnerable to Unprotected Transport of Credentials in the SecurityScorecard node, whose report download operation attaches the SecurityScorecard API token to a request sent to a user-specified URL. A user with permission to create or modify workflows and access to a SecurityScorecard credential can exfiltrate that token by configuring the report download operation to target an attacker-controlled host, which then receives the token on the outbound request and defeats the domain restrictions set on the credential. Exploitation requires an authenticated user who holds a SecurityScorecard credential and can edit workflows.
