{"cve":"CVE-2026-47268","nvd":{"published":"2026-06-12T22:16:51.390","modified":"2026-10-25T23:10:00.167","status":"Deferred","description":"Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O&M tool. From version 0.20.0 to before version 2.0.10, an authenticated Nezha dashboard user can create or update a DDNS profile with provider webhook and configure an arbitrary webhook_url, HTTP method, request body, and headers. When DDNS is triggered for a server that uses that profile, the dashboard process sends the configured request with utils.HttpClient without the SSRF protections used by notification webhooks. This allows a low-privileged authenticated user who controls an owned server/DDNS profile to make the dashboard host issue HTTP requests to loopback or internal network services. The response body is not returned to the attacker in the confirmed path, so this is a blind SSRF / internal state-changing request primitive. This issue has been patched in version 2.0.10.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-918"],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-6x26-5727-rrm9","https://github.com/nezhahq/nezha/security/advisories/GHSA-6x26-5727-rrm9"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-47268","score":0.00182,"percentile":0.07744,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-6x26-5727-rrm9","url":"https://osv.dev/vulnerability/GHSA-6x26-5727-rrm9","summary":"Nezha's authenticated DDNS webhook configuration allows blind SSRF from the dashboard host","modified":"2026-06-26T21:45:24.298221668Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=0.20.0 <2.0.10"],"fixed":["2.0.10"]},{"ecosystem":"Go","name":"github.com/naiba/nezha","purl":"pkg:golang/github.com/naiba/nezha","ranges":[">=0.20.0"],"fixed":[]}]},{"id":"GO-2026-5194","url":"https://osv.dev/vulnerability/GO-2026-5194","summary":"Nezha's authenticated DDNS webhook configuration allows blind SSRF from the dashboard host in github.com/nezhahq/nezha in github.com/naiba/nezha","modified":"2026-06-25T19:45:13.841026351Z","packages":[{"ecosystem":"Go","name":"github.com/naiba/nezha","purl":"pkg:golang/github.com/naiba/nezha","ranges":[">=0.20.0"],"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).
