Mongodb: Aggregation Framework Memory Exhaustion Leading to Process Termination (CVE-2026-13076)
CVE-2026-13076 is a high-severity vulnerability in MongoDB versions 8.3.0 through 8.3.6 where an authenticated user with write access can cause the mongod process to be terminated by the operating system due to excessive memory consumption during a specific data type conversion in the aggregation framework. This leads to process termination under memory pressure conditions.
AI Analysis
Technical Summary
This vulnerability allows an authenticated user who has write permissions and the ability to run aggregation queries in MongoDB to trigger disproportionate memory consumption by performing a particular data type conversion operation within the aggregation framework. The excessive memory usage can cause the operating system to terminate the mongod process, resulting in a denial of service. The issue affects MongoDB versions from 8.3.0 up to but not including 8.3.7. A patch is available to address this vulnerability.
Potential Impact
An attacker with authenticated write access can cause the MongoDB server process to be terminated by exhausting memory during aggregation operations, leading to denial of service. There is no indication of data corruption or unauthorized data access from the provided information.
Mitigation Recommendations
A patch is available for this vulnerability. Users should upgrade MongoDB to version 8.3.7 or later to remediate the issue. Since this is not a cloud service, remediation requires applying the patch on affected deployments.
