CVE-2026-57190: Asterisk SQL injection in CEL event logging

CVE-2026-57190 · Severity: info · Published 2026-10-27

Asterisk is an open-source telephony server that handles call routing and event logging. A flaw in the Channel Event Log (CEL) backends for PostgreSQL and MSSQL databases allows attackers to execute arbitrary SQL commands by injecting malicious data through the CELGenUserEvent dialplan application, potentially leading to unauthorized data access or modification in the call logging database.

Technical details

SQL injection vulnerability in cel_pgsql.c and cel_tds.c where the eventtype field is inserted directly into SQL queries without proper escaping or sanitization. While other string fields in these modules correctly use PQescapeStringConn() (PostgreSQL) and anti_injection() (MSSQL), the user_defined_name field bypasses these protections. An attacker with the ability to call CELGenUserEvent in the dialplan can inject arbitrary SQL through this field to read or modify database contents.
