CVE-2026-50747 is a critical authenticated SQL injection vulnerability affecting the UniFi Talk Application. The issue consists of a series of SQL injection flaws that can be reached by an attacker with network access who holds low-privileged authenticated access to the application. Insufficient neutralization of attacker-controlled input in SQL queries allows malicious database operations to be performed in the application context. Successful exploitation can be used to escalate privileges on the host device and gain broader control beyond the initial low-privileged account. Reported affected versions include UniFi Talk 5.1.2 and earlier, with the issue fixed in version 5.2.2.
