{"id":"CVE-2026-59155","summary":"Nezha Monitoring: DDNS and Notification credential exposure via unredacted list API","details":"Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. 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.","aliases":["GHSA-ww5p-j6cj-6mqq","GO-2026-5832"],"modified":"2026-07-16T03:30:48.800120122Z","published":"2026-07-10T21:31:34.313Z","database_specific":{"cwe_ids":["CWE-200"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59155.json","cna_assigner":"GitHub_M"},"references":[{"type":"WEB","url":"https://github.com/nezhahq/nezha/releases/tag/v2.2.5"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59155.json"},{"type":"ADVISORY","url":"https://github.com/nezhahq/nezha/security/advisories/GHSA-ww5p-j6cj-6mqq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59155"},{"type":"FIX","url":"https://github.com/nezhahq/nezha/commit/39d398066d8c644fe452f74704e34ada6c7ab61e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nezhahq/nezha","events":[{"introduced":"0"},{"fixed":"39d398066d8c644fe452f74704e34ada6c7ab61e"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.2.5"}]}}],"versions":["v2.2.4","v2.2.3","v2.2.2","v2.2.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59155.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
