Mongodb: $rankFusion and $scoreFusion Unbounded Memory Allocation During Error Suggestion Generation (CVE-2026-13075)
An authenticated user in MongoDB can trigger unbounded memory allocation during error suggestion generation involving the $rankFusion and $scoreFusion aggregation stages. This can cause the mongod process to be terminated by the operating system under memory pressure. The vulnerability arises from the server's error-handling path and requires the ability to run aggregation queries. A patch is available to address this issue.
AI Analysis
Technical Summary
CVE-2026-13075 affects MongoDB versions 8.2.0 through before 8.2.12 and 8.3.0 through before 8.3.7. The vulnerability allows an authenticated user to cause the mongod process to be terminated due to unbounded memory allocation triggered during error suggestion generation in the $rankFusion and $scoreFusion aggregation stages. The root cause is in the server's error-handling path when processing these aggregation queries. Exploitation requires authentication and the ability to run aggregation queries. No known exploits are reported in the wild. A patch is available to fix this issue.
Potential Impact
Successful exploitation can cause the MongoDB server process (mongod) to be terminated by the operating system due to excessive memory consumption, resulting in denial of service. This impacts availability but does not indicate direct data compromise or privilege escalation based on the provided information.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade MongoDB to versions 8.2.12 or later and 8.3.7 or later to remediate the issue. No additional mitigation steps are indicated by the vendor advisory.
