CVE-2025-57819· NVD / CVE Program· CNA GitHub_M

FreePBX Affected by Authentication Bypass Leading to SQL Injection and RCE

FreePBX is an open-source web-based graphical user interface. FreePBX 15, 16, and 17 endpoints are vulnerable due to insufficiently sanitized user-supplied data allowing unauthenticated access to FreePBX Administrator leading to arbitrary database manipulation and remote code execution. This issue has been patched in endpoint versions 15.0.66, 16.0.89, and 17.0.3.

The score given by the assigning authority versus NVD’s independent score. A gap means the severity is contested.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Aug 29, 2025. That signals real attacks, not theory.

Remediation deadline for government agencies: Sep 19, 2025.
