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.","published":"2026-03-30T17:59:19.393Z","modified":"2026-08-12T03:51:19.002998696Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","fixedVersion":null},{"ecosystem":"Go","name":"github.com/uozi-tech/cosy","fixedVersion":"1.30.1"}],"fix":null,"references":[{"type":"WEB","url":"https://github.com/0xJacky/nginx-ui/releases/tag/v2.3.4"},{"type":"ADVISORY","url":"https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-m468-xcm6-fxg4"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/33xxx/CVE-2026-33028.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-33028"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:19.002998696Z"}}
