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.","state":0,"publishedAt":"2026-06-12T21:00:46.7+00:00","modifiedAt":"2026-06-15T19:27:36.716+00:00","affected":[{"ecosystem":"Vendor product","name":"nezha","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"nezhahq\",\n                    \"product\": \"nezha\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 1.4.0, < 2.0.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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,"severity":"CRITICAL"}],"references":["https://github.com/nezhahq/nezha/security/advisories/GHSA-99gv-2m7h-3hh9"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-46716","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-46716","identifiers":["CVE-2026-46716"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
