An authenticated user with write access to a MongoDB database can cause the mongod process to be terminated by the operating system under conditions of memory pressure. This occurs by performing a specific data type conversion operation within MongoDB's aggregation framework that leads to disproportionate memory consumption. The vulnerability requires the ability to run aggregation queries and write data. No patch or remediation details are currently provided.
AI Analysis
Technical Summary
CVE-2026-13076 is a vulnerability in MongoDB where an authenticated user with write permissions can trigger excessive memory consumption during a specific data type conversion operation within the aggregation framework. This disproportionate memory usage can cause the operating system to terminate the mongod process when memory pressure is high. Exploitation requires both write access and the ability to execute aggregation queries. There are no known exploits in the wild and no vendor advisory or patch information is currently available.
Potential Impact
Successful exploitation can cause denial of service by terminating the mongod process, potentially disrupting database availability. The impact is limited to users with authenticated write access and aggregation execution privileges. There is no indication of data corruption or privilege escalation from the provided information.
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 risk.
