Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-46716 exists.\n\nAffected packages and fixed versions:\n- github.com/nezhahq/nezha (Go): affected from 1.4.0; fixed in 1.14.15-0.20260517022419-d7526351cf97\n- github.com/nezhahq/nezha (Go): affected from 1.4.0; fixed in 1.14.15-0.20260517022419-d7526351cf97\n- github.com/nezhahq/nezha (Go): affected from 1.4.0; fixed in 1.14.15-0.20260517022419-d7526351cf97\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-46716/ (Markdown: https://insights.sbomify.com/CVE-2026-46716/index.md)","id":"CVE-2026-46716","markdown":"https://insights.sbomify.com/CVE-2026-46716/index.md","name":"CVE-2026-46716","record":{"aliases":["GHSA-99gv-2m7h-3hh9","GO-2026-5282"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Nezha Monitoring","requires_auth":"low_privilege","summary":"A low-privileged user can execute arbitrary shell commands on all monitored servers, including those of other tenants, via a crafted cron task.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"},{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"},{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"Nezha Monitoring is a self-hostable, lightweight, servers and websites monitoring and O\u0026M tool.

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.
