      <title>CVE-2026-33028 — Nginx UI: Race Condition Leads to Persistent Data Corruption and Service Collapse</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-33028</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; 0xJacky nginx-ui&lt;/p&gt;
&lt;p&gt;Nginx UI is a web user interface for the Nginx web server. Prior to version 2.3.4, the nginx-ui application is vulnerable to a Race Condition. Due to the complete absence of synchronization mechanisms (Mutex) and non-atomic file writes, concurrent requests lead to the severe corruption of the primary configuration file (app.ini). This vulnerability results in a persistent Denial of Service (DoS) and introduces a non-deterministic path for Remote Code Execution (RCE) through configuration cross-contamination. This issue has been patched in version 2.3.4.&lt;/p&gt;</description>
