Summary

CVE-2026-37008 is a high-severity Improper Protection of Alternate Path (CWE-424) vulnerability in Yerangamage (inferred from references). Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique File and Directory Discovery (T1083); ranked at the 3th 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-25 (Reference Monitor) — see the control section below for these in your framework.

Vulnerability Data

CrewAI before fb2323b offers a Python blocklist approach that operates at the wrong level of abstraction, a different vulnerability than CVE-2026-2275. Import-time blocking of module names does not address the availability of Python's complete object graph. For example, calling ctypes.CDLL(None)…

loads the C library without relying in any import statements. In other words, a within-process sandbox cannot merely account for the import system and instead must account for the complete runtime of the Python interpreter.

Mitigating Controls (NIST 800-53 r5) AI

AC-24 Access Control Decisions partial match

Requiring access-control decisions to be applied to each request ensures no alternate path can bypass authorization checks.

AC-25 Reference Monitor partial match

A reference monitor that is always invoked by definition covers every possible path, eliminating the root cause of unprotected alternate paths.

AC-3 Access Enforcement partial match

Enforcing approved authorizations for every logical access request structurally blocks unprotected alternate paths to restricted resources.

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.AA-05 partial match
prevents

Enforcing and reviewing authorizations across all access paths directly prevents alternate-path bypasses.

PR.IR-01 partial match
prevents

Logical segmentation and unauthorized-access protections reduce the attack surface of unprotected alternate paths.

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.5.15 Access control partial match
prevents

Access control policy directly requires protection of all entry points to restricted functionality.

A.5.18 Access rights partial match
prevents

Managing access rights must cover every alternate path that could bypass intended restrictions.

A.8.2 Privileged access rights partial match
prevents

Privileged access rights must be enforced on every possible route to privileged functions.

A.8.20 Networks security partial match
mitigates

Network security can limit some alternate paths but is not the primary control for application-level path protection.

A.8.25 Secure development life cycle partial match
prevents

Secure development lifecycle includes design reviews that should identify and close alternate paths.

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

Secure architecture principles require eliminating unauthorized entry points during design.
