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.","cvss_v4":{"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},"cvss_v3":null,"cwes":["CWE-200"],"references":["https://github.com/nezhahq/nezha/commit/39d398066d8c644fe452f74704e34ada6c7ab61e","https://github.com/nezhahq/nezha/releases/tag/v2.2.5","https://github.com/nezhahq/nezha/security/advisories/GHSA-ww5p-j6cj-6mqq","https://github.com/nezhahq/nezha/security/advisories/GHSA-ww5p-j6cj-6mqq"],"products":[],"source":"nvd","synced_at":"2026-10-25T17:50:06.907763985+00:00"},"epss":{"cve":"CVE-2026-59155","score":0.00483,"percentile":0.41344,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-ww5p-j6cj-6mqq","url":"https://osv.dev/vulnerability/GHSA-ww5p-j6cj-6mqq","summary":"Nezha Dashboard: DDNS and Notification credential exposure via unredacted list API","modified":"2026-07-12T04:11:12.353970407Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":["<2.2.5"],"fixed":["2.2.5"]}]},{"id":"GO-2026-5832","url":"https://osv.dev/vulnerability/GO-2026-5832","summary":"Nezha Dashboard: DDNS and Notification credential exposure via unredacted list API in github.com/nezhahq/nezha","modified":"2026-07-12T04:11:12.353970407Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":["all versions"],"fixed":[]}]}],"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).
