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."}],"affected":[{"source":"security-advisories@github.com","affectedData":[{"vendor":"nezhahq","product":"nezha","versions":[{"version":">= 1.4.0, < 2.0.8","status":"affected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","baseScore":9.9,"baseSeverity":"CRITICAL","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"CHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":3.1,"impactScore":6.0}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-06-15T17:06:02.929846Z","id":"CVE-2026-46716","options":[{"exploitation":"poc"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-78"},{"lang":"en","value":"CWE-269"},{"lang":"en","value":"CWE-862"}]}],"references":[{"url":"https://github.com/nezhahq/nezha/security/advisories/GHSA-99gv-2m7h-3hh9","source":"security-advisories@github.com"},{"url":"https://github.com/nezhahq/nezha/security/advisories/GHSA-99gv-2m7h-3hh9","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0"}]}
