An authenticated user with read-only privileges can cause the mongod process to terminate abnormally by issuing a crafted aggregation command. This leads to a denial of service for all connected clients until the process is restarted. The root cause is an internal engine selection inconsistency triggered by a specific combination of aggregation options.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13073) allows an authenticated user with only read-only access to cause the MongoDB daemon (mongod) to crash by sending a specially crafted aggregation command. The issue arises from an inconsistency in the internal engine selection logic when certain aggregation options are combined, resulting in an abnormal termination of the mongod process and causing denial of service until manual restart.
Potential Impact
Successful exploitation results in denial of service affecting all clients connected to the affected mongod instance. The service remains unavailable until the process is manually restarted. No privilege escalation or data compromise is indicated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting aggregation command usage or monitoring for unusual aggregation queries from authenticated users with read-only privileges. No official fix or workaround is currently documented.
