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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:L/VI:H/VA:H/SC:N/SI:N/SA:N","score":7.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.5},"cwes":["CWE-362"],"references":["https://github.com/0xJacky/nginx-ui/releases/tag/v2.3.4","https://github.com/0xJacky/nginx-ui/security/advisories/GHSA-m468-xcm6-fxg4"],"products":["nginxui:nginx_ui","uozi:cosy"],"source":"nvd","synced_at":"2026-10-19T22:28:18.033120106+00:00"},"epss":{"cve":"CVE-2026-33028","score":0.00554,"percentile":0.4629,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-m468-xcm6-fxg4","url":"https://osv.dev/vulnerability/GHSA-m468-xcm6-fxg4","summary":"nginx-ui has Race Condition that Leads to Persistent Data Corruption and Service Collapse","modified":"2026-09-10T03:51:00.585682463Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["<=1.99"],"fixed":[]},{"ecosystem":"Go","name":"github.com/uozi-tech/cosy","purl":"pkg:golang/github.com/uozi-tech/cosy","ranges":["<1.30.1"],"fixed":["1.30.1"]}]},{"id":"GO-2026-4906","url":"https://osv.dev/vulnerability/GO-2026-4906","summary":"nginx-ui has Race Condition that Leads to Persistent Data Corruption and Service Collapse in github.com/0xJacky/Nginx-UI","modified":"2026-04-02T21:20:06.604028Z","packages":[{"ecosystem":"Go","name":"github.com/0xJacky/Nginx-UI","purl":"pkg:golang/github.com/0xJacky/Nginx-UI","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/uozi-tech/cosy","purl":"pkg:golang/github.com/uozi-tech/cosy","ranges":["<1.30.1"],"fixed":["1.30.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
