Prior to 2.2.5, the GET /api/v1/ddns and GET /api/v1/notification endpoints return full resource objects including plaintext third-party API credentials, including Cloudflare API tokens, TencentCloud SecretKeys, Slack, Discord, and Telegram webhook URLs with embedded bot tokens, and Authorization header values, without any field-level redaction. Any authenticated admin or PAT with nezha:ddns:read or nezha:notification:read scope can receive stored credentials through the listDDNS and listNotification handlers in a single API response. This issue is fixed in version 2.2.5.","state":0,"publishedAt":"2026-07-10T21:31:34.313+00:00","modifiedAt":"2026-07-13T17:56:44.683+00:00","affected":[{"ecosystem":"Vendor product","name":"nezha","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nezhahq\",\n                    \"product\": \"nezha\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.2.5\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N","score":6.9,"severity":"MEDIUM"}],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-ww5p-j6cj-6mqq","https://github.com/nezhahq/nezha/commit/39d398066d8c644fe452f74704e34ada6c7ab61e","https://github.com/nezhahq/nezha/releases/tag/v2.2.5"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-59155","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-59155","identifiers":["CVE-2026-59155"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
