CVE-2026-120046 Details
Description
Nezha 2.0.0 before 2.4.0 contains a NULL pointer dereference vulnerability in ServiceSentinel.loadTodayStats that allows authenticated users to crash the dashboard by deleting a service. Attackers can delete their own service via POST /api/v1/batch-delete/service, leaving orphaned service_histories rows that crash the non-TSDB dashboard on its next startup until removed manually.
A NULL pointer dereference vulnerability has been identified in Nezha versions 2.0.0 prior to 2.4.0. This vulnerability resides in the ServiceSentinel.loadTodayStats function, where it allows authenticated users to crash the dashboard by deleting a service. Users can delete their own services through the POST /api/v1/batch-delete/service endpoint. This action leaves behind orphaned service_history records, which cause the non-TSDB dashboard to crash on the next startup. The issue persists until the orphaned records are removed manually.
Users can upgrade to Nezha version 2.4.0 or later, where this vulnerability has been fixed.
