Prior to version 2.0.13, fallbackToFrontend in the dashboard's NoRoute handler treats any URL whose raw string starts with /dashboard as an admin-frontend asset request. The check uses strings.HasPrefix, not a path-segment match, so the input /dashboard../data/config.yaml is accepted; strings.TrimPrefix leaves ../data/config.yaml; and path.Join(\"admin-dist\", \"../data/config.yaml\") normalizes to data/config.yaml — which os.Stat finds and http.ServeFile returns. No authentication required. This issue has been patched in version 2.0.13.","state":0,"publishedAt":"2026-06-12T21:03:48.844+00:00","modifiedAt":"2026-06-15T18:27:12.779+00:00","affected":[{"ecosystem":"Vendor product","name":"nezha","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nezhahq\",\n                    \"product\": \"nezha\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.0.13\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N","score":9.1,"severity":"CRITICAL"}],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-5c25-7vpj-9mqh"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-53519","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-53519","identifiers":["CVE-2026-53519"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
