{"cve":"CVE-2026-46717","nvd":{"published":"2026-06-12T22:16:50.957","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 1.4.0 to before version 2.0.8, nezha's dashboard supports two user roles: RoleAdmin (Role==0) and RoleMember (Role==1). The notification routes POST /api/v1/notification and PATCH /api/v1/notification/:id are wired through commonHandler rather than adminHandler — so a RoleMember user can call them. These handlers synchronously Send() an HTTP request to a user-controlled URL and reflect the entire response body (no size limit) back to the caller on any non-2xx response. This issue has been patched in version 2.0.8.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N","score":7.7},"cwes":["CWE-863","CWE-918"],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-w4g9-mxgg-j532","https://github.com/nezhahq/nezha/security/advisories/GHSA-w4g9-mxgg-j532"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-46717","score":0.0027,"percentile":0.18993,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-w4g9-mxgg-j532","url":"https://osv.dev/vulnerability/GHSA-w4g9-mxgg-j532","summary":"Nezha Monitoring: RoleMember-reachable SSRF with full response-body reflection via POST /api/v1/notification","modified":"2026-06-26T21:45:24.336102077Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=1.4.0 <1.14.15-0.20260517022419-d06d539d34c1"],"fixed":["1.14.15-0.20260517022419-d06d539d34c1"]}]},{"id":"GO-2026-5687","url":"https://osv.dev/vulnerability/GO-2026-5687","summary":"Nezha Monitoring: RoleMember-reachable SSRF with full response-body reflection via POST /api/v1/notification in github.com/nezhahq/nezha","modified":"2026-06-25T23:01:40.048871517Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=1.4.0 <1.14.15-0.20260517022419-d06d539d34c1"],"fixed":["1.14.15-0.20260517022419-d06d539d34c1"]}]}],"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).
