Summary

CVE-2026-13056 is a high-severity Improperly Controlled Sequential Memory Allocation (CWE-1325) vulnerability in Mongodb Mongodb. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Endpoint Denial of Service (T1499); ranked at the 21th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-6 (Resource Availability) — see the control section below for these in your framework.

Vulnerability Data

Using expressions that generate large arrays it is possible to craft a query that creates very large intermediate objects in memory, causing the server to crash with OOM error.

Mitigating Controls (NIST 800-53 r5) AI

SC-6 Resource Availability good match

SC-6 directly enforces resource quotas and priority allocations that stop unbounded sequential memory requests from exhausting the system.

Mitigating Controls (NIST CSF 2.0) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require developers to enforce total memory limits during sequential allocations.

Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing can detect unbounded allocation patterns, but removing the weakness does not fulfill testing obligations.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle includes resource-management requirements that can prevent uncontrolled per-object allocations.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles can mandate bounded resource usage, but eliminating this CWE does not address broader architectural controls.

A.8.28 Secure coding partial match
prevents

Secure coding standards can require explicit limits on memory per object, yet fixing the weakness alone does not satisfy the full control.

A.8.6 Capacity management partial match
mitigates

Capacity management directly limits total memory consumption across objects, mitigating unbounded sequential allocations.
