CVE-2026-53448
Description
A flaw was found in Coturn, a free open-source implementation of TURN and STUN Server. 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.
Statement
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.
Mitigation
No action needed — the shipped coturn build (4.14.0) already contains the upstream fix.
