Summary

CVE-2025-26412 is a medium-severity Hidden Functionality (CWE-912) vulnerability in Sec Consult (inferred from references). Its CVSS base score is 6.8 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Redundant Access (T1108); ranked at the 17th 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 CM-2 (Baseline Configuration) and CM-7 (Least Functionality) — see the control section below for these in your framework.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

CM-2 Baseline Configuration good match

Maintaining and reviewing a documented baseline configuration allows comparison that reveals any functionality absent from the approved specification.

CM-7 Least Functionality good match

Least-functionality configuration explicitly prohibits or restricts any capability not required by the approved baseline, blocking hidden additions.

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation activities are designed to discover undocumented or unspecified functionality after it has been introduced.

SA-15 Development Process, Standards, and Tools partial match

Documented development processes and standards require all functionality to be specified and visible, structurally preventing undocumented hidden features.

SA-3 System Development Life Cycle partial match

An SDLC that incorporates security engineering principles mandates that all product functions be part of the approved specification.

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 full match
prevents

Secure SDLC practices directly prevent introduction of undocumented hidden functionality during development.

ID.RA-09 mostly match
prevents

Pre-acquisition integrity/authenticity checks can detect undocumented hidden functions in supplied software/hardware.

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 in development and acceptance can discover undocumented functionality before release.

A.8.32 Change management mostly match
prevents

Change management processes can catch unauthorized additions but do not inherently prevent hidden functionality from being introduced.

A.8.16 Monitoring activities partial match
finds

Monitoring activities can detect anomalous behavior from hidden functions but do not eliminate the weakness.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates documented requirements and design reviews that would expose undocumented hidden functionality.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly define expected functionality, making hidden features a violation.

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

Secure system architecture and engineering principles require transparent, documented designs that preclude hidden functionality.
