{"id":"CVE-2026-46717","aliases":["GHSA-w4g9-mxgg-j532","GO-2026-5687"],"url":"https://o3.security/vulnerability/CVE-2026-46717","summary":"Nezha Monitoring: RoleMember-reachable SSRF with full response-body reflection via POST /api/v1/notification","details":"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.","published":"2026-06-12T21:02:40.951Z","modified":"2026-08-12T03:51:25.853560599Z","cvss":{"score":7.7,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","fixedVersion":"1.14.15-0.20260517022419-d06d539d34c1"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46717.json"},{"type":"ADVISORY","url":"https://github.com/nezhahq/nezha/security/advisories/GHSA-w4g9-mxgg-j532"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46717"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:25.853560599Z"}}
