An authenticated user with read access to a MongoDB server can cause the mongod process to terminate by using certain aggregation expressions that execute server-side JavaScript. This vulnerability is due to improper memory handling during document processing, leading to potential process crashes.
AI Analysis
Technical Summary
CVE-2026-13071 is a vulnerability in MongoDB where an authenticated user with read privileges can trigger a termination of the mongod process. The issue arises from improper memory handling (use-after-free, CWE-416) when processing aggregation expressions that execute server-side JavaScript. This can cause the database server process to crash, resulting in denial of service conditions.
Potential Impact
Successful exploitation allows an authenticated user with read access to cause the mongod process to terminate unexpectedly. This results in denial of service, potentially disrupting database availability. There is no indication of privilege escalation or data corruption from the provided data.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict read access to trusted users only and monitor for unusual aggregation queries that might trigger this issue.
