## Overview

Froxlor before 2.3.13 returns the ssl_key_file column — which stores the raw PEM TLS private-key content — verbatim in the JSON responses of the Certificates.get and Certificates.listing API commands, because the results of the underlying domain_ssl_settings queries are passed through ApiCommand::response() without any field stripping or allowlist. A low-privileged authenticated customer API caller can retrieve the private keys of their own domains' certificates, including Let's Encrypt keys that Froxlor generates server-side and stores root-only (0600) and to which the customer otherwise has no filesystem access; reseller and customers_see_all admin accounts can dump the private keys of other principals through the same sink. Disclosed keys enable domain impersonation, passive decryption of captured TLS traffic, and active machine-in-the-middle attacks.
