Summary

CVE-2026-57869 is a high-severity Authorization Bypass Through User-Controlled Key (CWE-639) vulnerability in Com (inferred from references). Its CVSS base score is 7.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked at the 12th 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-24 (Access Control Decisions) and AC-3 (Access Enforcement) — see the control section below for these in your framework.

Mitigating Controls (NIST 800-53 r5) AI

AC-3 Access Enforcement good match

Enforcing approved authorizations on every access request structurally stops a user-controlled key from reaching another user's data.

AC-24 Access Control Decisions good match

Requiring explicit access-control decisions on each request blocks unauthorized key-driven access.

SC-13 Cryptographic Protection good match

Specifying required cryptographic mechanisms and algorithms precludes predictable RNG implementations.

AC-6 Least Privilege partial match

Least-privilege restrictions limit the scope of data reachable even if a key check is bypassed.

SA-8 Security and Privacy Engineering Principles partial match

Security engineering principles require selection of cryptographically secure RNG algorithms instead of predictable ones.

SC-12 Cryptographic Key Establishment and Management partial match

Cryptographic key establishment and management mandates use of unpredictable random values for key material.

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.AA-05 full match
prevents

Enforcing authorization policy and least privilege directly blocks user-controlled key tampering that bypasses access checks.

PR.IR-01 mostly match
prevents

Logical access controls prevent unauthorized data access that results from missing authorization checks on object references.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require cryptographically strong RNGs, preventing predictable algorithms at design time.

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

Security testing can detect missing authorization checks but does not prevent the weakness in production.

A.8.3 Information access restriction mostly match
prevents

Information access restriction explicitly enforces that users may only retrieve data they are authorized to see, directly addressing user-controlled key bypass.

A.5.15 Access control partial match
prevents

Access control policy directly requires enforcement of authorization rules that prevent unauthorized access via manipulated keys.

A.5.18 Access rights partial match
prevents

Managing access rights includes ensuring users can only access their own records and not bypass authorization by altering identifiers.

A.8.2 Privileged access rights partial match
mitigates

Privileged access rights control restricts what data each user may access, mitigating direct object reference attacks.

A.8.24 Use of cryptography partial match
prevents

Mandates use of approved cryptographic algorithms and RNGs, directly preventing predictable PRNGs.
