{"id":"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.","aliases":["GHSA-w4g9-mxgg-j532","GO-2026-5687"],"modified":"2026-08-12T03:51:25.853560599Z","published":"2026-06-12T21:02:40.951Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-863","CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46717.json"},"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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nezhahq/nezha","events":[{"introduced":"7540e80f20f1be25ac3b8678af3fb9e4aabd27ac"},{"fixed":"e1244ca3721cc1f0abe83da6403362e86bf04541"}],"database_specific":{"extracted_events":[{"introduced":"1.4.0"},{"fixed":"2.0.8"},{"introduced":"0"}],"source":["AFFECTED_FIELD","DESCRIPTION"]}}],"versions":["v2.0.7","v2.0.6","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.0","v1.14.14","v1.14.13","v1.14.12","v1.14.11","v1.14.10","v1.14.9","v1.14.8","v1.14.7","v1.14.6","v1.14.5","v1.14.4","v1.14.3","v1.14.2","v1.14.1","v1.14.0","v1.13.2","v1.13.1","v1.13.0","v1.12.4","v1.12.3","v1.12.2","v1.12.1","v1.12.0","v1.11.0","v1.10.8","v1.10.7","v1.10.6","v1.10.5","v1.10.4","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.11","v1.9.10","v1.9.9","v1.9.8","v1.9.7","v1.9.6","v1.9.5","v1.9.4","v1.9.3","v1.9.2","v1.9.1","v1.9.0","v1.8.2","v1.8.1","v1.8.0","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.9","v1.6.8","v1.6.7","v1.6.6","v1.6.5","v1.6.4","v1.6.3","v1.6.2","v1.6.1","v1.6.0","v1.5.13","v1.5.12","v1.5.11","v1.5.10","v1.5.9","v1.5.8","v1.5.7","v1.5.6","v1.5.5","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.9","v1.4.8","v1.4.7","v1.4.6","v1.4.5","v1.4.4","v1.4.3","v1.4.2","v1.4.1","v1.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46717.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
