CVE-2026-13075: CWE-770: Allocation of Resources Without Limits or Throttling in MongoDB MongoDB Server
CVE-2026-13075 is a high-severity vulnerability in MongoDB Server versions 8.2.0 and 8.3.0. An authenticated user with the ability to run aggregation queries can cause the mongod process to be terminated by the operating system due to memory pressure triggered via the $rankFusion and $scoreFusion aggregation stages. The issue arises from the server's error-handling path and involves allocation of resources without limits or throttling.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13075) affects MongoDB Server versions 8.2.0 and 8.3.0. It involves improper resource allocation control (CWE-770) in the $rankFusion and $scoreFusion aggregation stages. An authenticated user can exploit this by running aggregation queries that cause excessive memory consumption, leading the operating system to terminate the mongod process under memory pressure. The root cause is in the server's error-handling path, which does not properly limit resource allocation during these operations.
Potential Impact
The impact of this vulnerability is denial of service (DoS) against the MongoDB Server process. An authenticated user can cause the mongod process to be terminated by the operating system, disrupting database availability. There is no indication of privilege escalation, data corruption, or data leakage from the provided information.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict authenticated user permissions to prevent use of the $rankFusion and $scoreFusion aggregation stages if possible, or monitor and limit resource consumption of aggregation queries.
