{"id":"CVE-2026-46716","summary":"Nezha Monitoring: RoleMember can run shell on every server (cross-tenant RCE) via POST /api/v1/cron","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, 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.","aliases":["GHSA-99gv-2m7h-3hh9","GO-2026-5282"],"modified":"2026-08-12T03:51:29.448542441Z","published":"2026-06-12T21:00:46.700Z","related":["openSUSE-SU-2026:21483-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46716.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-269","CWE-78","CWE-862"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46716.json"},{"type":"ADVISORY","url":"https://github.com/nezhahq/nezha/security/advisories/GHSA-99gv-2m7h-3hh9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46716"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nezhahq/nezha","events":[{"introduced":"7540e80f20f1be25ac3b8678af3fb9e4aabd27ac"},{"fixed":"e1244ca3721cc1f0abe83da6403362e86bf04541"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"1.4.0"},{"fixed":"2.0.8"},{"introduced":"0"}]}}],"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-2026-46716.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:H/A:H"}]}
