Summary

CVE-2026-82052 is a high-severity Reachable Assertion (CWE-617) vulnerability in Mongodb. Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Defense Impairment (T1687); ranked at the 42th 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 SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation finds reachable assertions during development.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles discourage use of assertions for handling untrusted input.

SI-10 Information Input Validation partial match

Validating untrusted inputs structurally prevents attacker data from reaching and triggering assertions.

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
blocks

Secure SDLC practices directly prevent unsafe assertions from being coded in reachable paths.

DE.CM-09 partial match
blocks

Runtime monitoring of software can detect assertion-triggered crashes as adverse events.

ID.RA-01 partial match
blocks

Vulnerability identification processes can discover and record reachable-assertion flaws before deployment.

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 in development can detect reachable assertions before release, reducing the likelihood of exploitation.

A.8.28 Secure coding partial match
prevents

Secure coding standards explicitly ban the use of assert() or equivalent statements that can be triggered by external input.
