CVE-2026-33028 is a high-severity race condition affecting Nginx UI versions prior to 2.3.4, including nginxui cosy and uozi nginx_ui. This vulnerability, rated CVSS 7.5, allows an attacker to corrupt the primary configuration file through concurrent requests due to a lack of synchronization mechanisms. This leads to persistent Denial of Service (DoS) and introduces a non-deterministic path for Remote Code Execution (RCE) via configuration cross-contamination. The attack has high complexity but can be executed over the network with low privileges. Currently, there is no evidence of active exploitation, no public exploit code available, and minimal community discussion or media coverage.
