CVE-2026-28210Network attack vector

Database disclosure and modification via unsanitized LIMIT values

Published Mar 5, 2026 · Updated Mar 5, 2026

SQL injection in FreePBX cdr 16 before 16.0.49 and 17 before 17.0.7 allows remote authenticated users to read and alter database data. The CDR Reports page inserts user-controlled LIMIT values directly into SQL queries without sufficient sanitization, enabling UNION and time-based blind injection. A known Administration Control Panel username and access to the affected CDR functionality are required; successful injection can expose or modify database records.
