AI Analysis
Technical Summary
Nezha Monitoring, a self-hostable monitoring tool, contains an information exposure vulnerability (CWE-200) in versions >=2.0.0 and <2.0.14. Private services intended to be hidden (with `EnableShowInService: false`) are still discoverable through specific server endpoints, leaking sensitive metadata such as service names and timing information. This vulnerability does not require privileges or user interaction and has a CVSS 3.1 base score of 5.3 (medium severity). The vulnerability was patched in version 2.0.14.
Potential Impact
Unauthorized actors can enumerate private services that should be hidden, gaining access to sensitive information including service names and timing data. This may aid attackers in reconnaissance but does not directly impact integrity or availability.
Mitigation Recommendations
Upgrade Nezha Monitoring to version 2.0.14 or later, where this vulnerability has been patched. No other mitigation or temporary fix is indicated.
