Summary

CVE-2026-93762 is a critical-severity Unsafe Reflection (CWE-470) vulnerability in Mongodb Mongoid. Its CVSS base score is 9.2 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Reflective Code Loading (T1620); ranked at the 45th 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 AC-3 (Access Enforcement) and AC-6 (Least Privilege) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Enforces authorization checks on the code or classes ultimately invoked, blocking unauthorized selections even if reflection is used.

Limits privileges of any code reached through unsafe reflection, reducing blast radius without stopping the selection itself.

Input validation directly stops externally supplied class or method names from selecting improper code via reflection.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover unsafe reflection during code review or scanning.

PR.PS-05 partial match
prevents

Preventing execution of unauthorized code can block exploitation of unsafe reflection at runtime.

PR.PS-06 partial match
prevents

Secure SDLC practices directly avoid introducing externally controlled class selection via reflection.

prevents

Secure development lifecycle mandates input validation and design reviews that reduce unsafe reflection risks.

prevents

Application security requirements can explicitly prohibit or constrain reflection based on untrusted input.

prevents

Secure architecture principles discourage dynamic class loading from external data sources.

prevents

Secure coding standards directly forbid unsafe reflection and require whitelisting or static alternatives.

finds

Security testing can detect and block unsafe reflection patterns before release.
