CVE-2026-53448: Coturn SQL injection in HTTPS admin panel delete operations

CVE-2026-53448 · Severity: high · CVSS 7.2 · Published 2026-07-10

Coturn is an open-source server used for relaying media traffic in VoIP and WebRTC applications. A security flaw in its web-based administration panel allows an authorized administrator to bypass intended restrictions and execute unauthorized database commands. This could lead to the deletion of all user accounts, the creation of backdoor access, or potentially full control over the underlying server operating system.

Technical details

An SQL injection vulnerability exists in the Coturn HTTPS admin panel due to the lack of input sanitization in the 'delete-user' (du), 'delete-secret' (ds), and 'delete-IP' (dip) handlers. While the STUN protocol path uses the 'is_secure_string' filter, the admin panel's 'turn_admin_server.c' component passes HTTP query parameters directly into SQL queries via 'snprintf' string interpolation. An authenticated attacker with admin privileges can inject arbitrary SQL commands. On PostgreSQL backends, this can be escalated to OS-level command execution via stacked queries and the 'COPY TO PROGRAM' command. The issue is resolved in version 4.12.0 by applying 'is_secure_string' and 'check_ip_list_range' validation to these parameters.
