CVE-2026-13076: CWE-770: Allocation of Resources Without Limits or Throttling in MongoDB MongoDB Server
CVE-2026-13076 is a high-severity vulnerability in MongoDB Server 8.3.0 where an authenticated user with write access can cause the mongod process to be terminated by the operating system due to excessive memory consumption. This occurs through a specific data type conversion operation within the aggregation framework, leading to resource exhaustion without limits or throttling.
AI Analysis
Technical Summary
This vulnerability (CWE-770) allows an authenticated user with write privileges to trigger disproportionate memory usage in MongoDB Server 8.3.0 by performing a particular data type conversion during aggregation queries. The excessive memory consumption can cause the operating system to terminate the mongod process under memory pressure, resulting in denial of service. The issue requires both the ability to run aggregation queries and write access to the database. No official patch or remediation level has been provided yet, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation results in denial of service by causing the mongod process to be terminated due to memory exhaustion. This disrupts database availability and may impact applications relying on the affected MongoDB instance. The attack requires authenticated write access and the ability to run aggregation queries, limiting the scope to users with elevated privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict write and aggregation query permissions to trusted users only to reduce the risk of exploitation.
