  • We dive into a new set of FreePBX issues beyond CVE-2025-57819: an authentication bypass in webserver mode (CVE-2025-66039), multiple SQL injections (CVE-2025-61675), and an arbitrary file upload bug leading to remote code execution (CVE-2025-61678). Together, they allow authenticated or unauthenticated attackers to achieve code execution on vulnerable FreePBX instances using risky auth settings. This write-up explains impact, exploitation paths, patched versions, and how NodeZero coverage helps you find and fix these exposures in your environment.
