Mongodb: Server-Side JavaScript Aggregation Expression Memory Safety Issue Leading to Process Termination (CVE-2026-13071)
CVE-2026-13071 is a high-severity vulnerability in MongoDB where an authenticated user with read access can cause the mongod process to terminate by leveraging certain server-side JavaScript aggregation expressions. The issue stems from improper memory handling during document processing, leading to a memory safety problem. Multiple MongoDB versions are affected, and an official patch is available to address this flaw.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-13071) affects MongoDB server versions 7.0.0 up to but not including 7.0.39, 8.0.0 up to 8.0.28, 8.2.0 up to 8.2.12, and 8.3.0 up to 8.3.7. It involves improper memory handling during the execution of server-side JavaScript aggregation expressions, which can be triggered by an authenticated user with read access. Exploiting this flaw causes the mongod process to terminate unexpectedly, resulting in a denial of service condition. The vulnerability is categorized under CWE-416 (Use After Free). No known exploits are reported in the wild. An official patch is available to remediate this issue.
Potential Impact
An attacker with authenticated read access can cause the MongoDB server process to crash, resulting in denial of service. This disrupts database availability but does not indicate direct data compromise or privilege escalation based on the provided information.
Mitigation Recommendations
An official patch is available for this vulnerability. Users should upgrade affected MongoDB versions to the fixed releases beyond 7.0.39, 8.0.28, 8.2.12, and 8.3.7 to mitigate the issue. No additional mitigation steps are indicated by the vendor advisory.
