Alert meAnalysisAIv1 – Mar 12, 2026
Unauthenticated SQL injection in the FreePBX CDR module (versions before 16.0.49 and 17.0.7) allows authenticated users to execute arbitrary SQL commands and potentially compromise the entire database. An attacker with valid credentials can exploit this vulnerability to read sensitive call records, modify system data, or escalate privileges within the FreePBX system. No patch is currently available, leaving affected installations at high risk until upgrades are deployed.

DescriptionGitHub Advisory
FreePBX is an open source IP PBX. Prior to versions 16.0.49 and 17.0.7, FreePBX module cdr (Call Data Record) is vulnerable to SQL query injection. This issue has been patched in versions 16.0.49 and 17.0.7.
Executive ViewAI
FreePBX installations are vulnerable to SQL injection attacks through the Call Data Record module, potentially allowing unauthorized access to sensitive call logs and customer data. Organizations running affected versions (pre-16.0.49 and pre-17.0.7) face immediate risk of data breach and system compromise, with no vendor patch currently available.
Implement network segmentation to restrict CDR module database access; deploy WAF rules to detect and block SQL injection payloads; disable CDR module temporarily if not business-critical; apply principle of least privilege to database service accounts; enable comprehensive audit logging for all CDR database queries; implement rate limiting on CDR API endpoints; monitor for CVE-2026-28210 exploit indicators in security logs.
