{"cve":"CVE-2026-46716","nvd":{"published":"2026-06-12T22:16:50.810","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, a RoleMember user can create a scheduled cron task with Cover=CronCoverAll, Servers=[] and an arbitrary Command. At every tick of the scheduler, the dashboard pushes that command to every server in the global ServerShared map — including servers that belong to other tenants (admin's servers, other members' servers). Each agent runs the command and returns the output, which is then sent to the attacker's own NotificationGroup → attacker-controlled webhook. 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:H/A:H","score":9.9},"cwes":["CWE-78","CWE-269","CWE-862"],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-99gv-2m7h-3hh9","https://github.com/nezhahq/nezha/security/advisories/GHSA-99gv-2m7h-3hh9"],"products":[],"source":"nvd","synced_at":"2026-10-25T23:44:33.281319194+00:00"},"epss":{"cve":"CVE-2026-46716","score":0.0043,"percentile":0.36974,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-99gv-2m7h-3hh9","url":"https://osv.dev/vulnerability/GHSA-99gv-2m7h-3hh9","summary":"Nezha Monitoring: RoleMember can run shell on every server (cross-tenant RCE) via POST /api/v1/cron","modified":"2026-06-26T21:45:24.340043794Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=1.4.0 <1.14.15-0.20260517022419-d7526351cf97"],"fixed":["1.14.15-0.20260517022419-d7526351cf97"]}]},{"id":"GO-2026-5282","url":"https://osv.dev/vulnerability/GO-2026-5282","summary":"Nezha Monitoring: RoleMember can run shell on every server (cross-tenant RCE) via POST /api/v1/cron in github.com/nezhahq/nezha","modified":"2026-06-25T19:45:24.954487460Z","packages":[{"ecosystem":"Go","name":"github.com/nezhahq/nezha","purl":"pkg:golang/github.com/nezhahq/nezha","ranges":[">=1.4.0 <1.14.15-0.20260517022419-d7526351cf97"],"fixed":["1.14.15-0.20260517022419-d7526351cf97"]}]}],"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).
