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.","affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/0xjacky/nginx-ui","events":[{"introduced":"0"},{"fixed":"20412b5b54f9e0473d5fbd10a964f4f3035c5521"}],"database_specific":{"cpe":"cpe:2.3:a:nginxui:nginx_ui:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.3.4"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}},{"type":"GIT","repo":"https://github.com/uozi-tech/cosy","events":[{"introduced":"0"},{"fixed":"e1cfc5d2b2c6792dce2db3b666813094a94dc820"}],"database_specific":{"cpe":"cpe:2.3:a:uozi:cosy:*:*:*:*:*:go:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.30.1"}],"source":"CPE_RANGE"}}],"versions":["v2.3.3","v2.3.2","v2.3.1","v2.3.0","v2.2.1","v2.2.0-patch.1","v2.2.0","v2.1.17","v2.1.16","v2.1.15","v2.1.14","v2.1.13","v2.1.12","v2.1.11","v2.1.10","v2.1.9","v2.1.8","v2.1.7","v2.1.6","v2.1.5","v2.1.4-patch.1","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0-patch.1","v2.1.0","v2.1.0-rc.3","v2.1.0-rc.2","v2.1.0-rc.1","v2.1.0-beta.1","v2.0.2","v2.0.1","v2.0.0","v2.0.0-rc.8-patch.1","v2.0.0-rc.8","v2.0.0-rc.7-patch.8","v2.0.0-rc.7-patch.7","v2.0.0-rc.7-patch.6","v2.0.0-rc.7-patch.5","v2.0.0-rc.7-patch.4","v2.0.0-rc.7-patch.3","v2.0.0-rc.7-patch.2","v2.0.0-rc.7","v2.0.0-rc.6-patch.5","v2.0.0-rc.6-patch.4","v2.0.0-rc.6-patch.3","v2.0.0-rc.6-patch.2","v2.0.0-rc.6-patch.1","v2.0.0-rc.6","v2.0.0-rc.5","v2.0.0-rc.4-patch.3","v2.0.0-rc.4-patch.2","v2.0.0-rc.4-patch.1","v2.0.0-rc.4","v2.0.0-rc.3-patch.1","v2.0.0-rc.3","v2.0.0-rc.2","v2.0.0-rc.1-patch.2","v2.0.0-rc.1-patch.1","v2.0.0-rc.1","v2.0.0-beta.42","v2.0.0-beta.41","v2.0.0-beta.40","v2.0.0-beta.39","v2.0.0-beta.38","v2.0.0-beta.37-patch.5","v2.0.0-beta.37-patch.4","v2.0.0-beta.37-patch.3","v2.0.0-beta.37-patch.2","v2.0.0-beta.37-patch.1","v2.0.0-beta.37","v2.0.0-beta.36","v2.0.0-beta.35","v2.0.0-beta.34","v2.0.0-beta.33","v2.0.0-beta.32-patch.1","v2.0.0-beta.32","v2.0.0-beta.31","v2.0.0-beta.30","v2.0.0-beta.29","v2.0.0-beta.28","v2.0.0-beta.27","v2.0.0-beta.26","v2.0.0-beta.25-patch.2","v2.0.0-beta.25-patch.1","v2.0.0-beta.25","v2.0.0-beta.24","v2.0.0-beta.23-patch.2","v2.0.0-beta.23-patch.1","v2.0.0-beta.23","v2.0.0-beta.22","v2.0.0-beta.21","v2.0.0-beta.20","v2.0.0-beta.19","v2.0.0-beta.18-patch.2","v2.0.0-beta.18-patch.1","v2.0.0-beta.18","v2.0.0-beta.17","v2.0.0-beta.16","v2.0.0-beta.15","v2.0.0-beta.14","v2.0.0-beta.13-patch","v2.0.0-beta.13","v2.0.0-beta.12","v2.0.0-beta.11","v2.0.0-beta.10-patch","v2.0.0-beta.10","v2.0.0-beta.9","v2.0.0-beta.8-patch","v2.0.0-beta.8","v2.0.0-beta.7","v2.0.0-beta.6-patch.2","v2.0.0-beta.6-patch","v2.0.0-beta.6","v2.0.0-beta.5-patch","v2.0.0-beta.5","v2.0.0-beta.4-patch","v2.0.0-beta.4","v2.0.0-beta.3","v2.0.0-beta.2","v2.0.0-beta.1","v1.9.9-4","v1.9.9-3","v1.9.9-2","v1.9.9","v1.9.9-1","v1.8.4-patch","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.9","v1.7.8","v1.7.7","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0-patch","v1.7.0","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.3","v1.6.2","v1.6.1","v1.6.0-fix","v1.6.0","v1.5.2","v1.5.1","v1.5.0","v1.5.0-beta9","v1.5.0-beta8","v1.5.0-beta7","v1.5.0-beta6","v1.5.0-beta5","v1.5.0-beta4-fix","v1.5.0-beta4","v1.5.0-beta3","v1.5.0-beta2","v1.5.0-beta1","v1.4.2","v1.4.1","v1.4.0","v1.4.0-rc1","v1.3.3-rc1","v1.3.2","v1.3.1-fix","v1.3.1","v1.3.0","v1.3.0-rc1","v1.2.2","v1.2.1","v1.2.0-rc.3","v1.2.0","v1.2.0-rc.2","v1.2.0-rc.1","v1.2.0-alpha.4","v1.2.0-alpha.3","v1.1.0","v1.30.0","v1.29.3","v1.29.2","v1.29.1","v1.29.0","v1.28.0","v1.27.9","v1.27.8","v1.27.7","v1.27.6","v1.27.5","v1.27.4","v1.27.3","v1.27.2","v1.27.1","v1.27.0","v1.26.19","v1.26.18","v1.26.17","v1.26.16","v1.26.15","v1.26.14","v1.26.13","v1.26.11","v1.26.10","v1.26.9","v1.26.8","v1.26.7","v1.26.5","v1.26.4","v1.26.3","v1.26.2","v1.26.1","v1.26.0","v1.25.9","v1.25.6","v1.25.5","v1.25.4","v1.25.3","v1.25.1","v1.25.0","1.24.11","v1.24.10","v1.24.9","v1.24.8","v1.24.7","v1.24.5","v1.24.4","v1.24.3","v1.24.2","v1.24.1","v1.24.0","v1.23.1","v1.23.0","1.23.0","v1.22.2","v1.22.1","v1.22.0","v1.21.2","v1.21.1","v1.21.0","v1.20.0","v1.19.1","v1.19.0","v1.18.0","v1.17.0","v1.16.0","v1.15.6","v1.15.5","v1.15.4","v1.15.3","v1.15.2","v1.15.1","v1.15.0","v1.14.5","v1.14.4","v1.14.3","v1.14.2","v1.14.1","v1.14.0","v1.13.0","v1.12.5","v1.12.4","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.0","v1.10.0","v1.9.14","v1.9.13","v1.9.12","v1.9.10","v1.9.8","v1.9.7","v1.9.6","v1.9.5","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.5.3","1.5.1","v1.4.5","v1.4.3","v1.3.3","v1.0.2","v1.0.1","v1.0.0","v0.9.2","v0.9.1","v0.9.0","v0.8.2","v0.8.1","v0.8.0","v0.7.1","v0.6.0","v0.5.0","v0.4.6","v0.4.5","v0.4.4","v0.4.2","v0.4.1","v0.4.0","v0.3.8","v0.3.7","v0.3.6","v0.3.5","v0.3.4","v0.3.3","v0.3.2","v0.3.1","v0.3.0","v0.2.4","v0.2.1","v0.2.0","v0.1.3","v0.1.2","v0.1.1","v0.1.0","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-33028.json"}}],"references":[{"type":"WEB","url":"https://github.com/0xJacky/nginx-ui/releases/t
