Summary
Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.12.0, the coturn HTTPS admin panel passes HTTP query parameters directly into SQL queries via snprintf string interpolation without sanitization.
The is_secure_string filter that protects the STUN protocol path is not applied to the admin panel's delete-user, delete-secret, and delete-IP operations, so an authenticated admin can inject arbitrary SQL through the du, ds, and dip parameters, gaining full database control and potentially OS-level access via PostgreSQL COPY TO PROGRAM.
This issue is fixed in version 4.12.0. The HTTPS administration panel, specifically in the delete-user, delete-secret, and delete-IP operations, does not properly sanitize HTTP query parameters.
This allows an authenticated administrator to inject arbitrary SQL (Structured Query Language) commands, leading to full control over the database. This could potentially enable an attacker to achieve arbitrary code execution on the underlying operating system.
This flaw affects the community-maintained coturn TURN/STUN server as shipped in Fedora and EPEL. Red Hat does not ship coturn in any core Red Hat product.
Fedora and EPEL currently ship coturn 4.14.0, which already includes the fix released in 4.12.0, so the shipped builds are not vulnerable to this SQL injection in the HTTPS admin panel.
Is CVE-2026-53448 exploited?
No exploitation is reported in the sources VulniPulse tracks: CVE-2026-53448 is not in the CISA KEV catalog (checked ) and this advisory does not report exploitation. That is not proof the vulnerability cannot be exploited.
