CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:HSummary
CVE-2026-27208 is a critical-severity OS Command Injection (CWE-78) vulnerability in Bleon-Ethical Api-Gateway-Deploy. Its CVSS base score is 9.2 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked at the 48th 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-2 (Account Management) and AC-24 (Access Control Decisions) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2026-27208 affects version 1.0.0 of bleon-ethical/api-gateway-deploy, an API gateway deployment tool. The vulnerability is an attack chain combining OS command injection (CWE-78, CWE-88) with privilege escalation (CWE-250, CWE-269), stemming from improper input handling and execution of commands as root within the container. It carries a CVSS v3.1 base score of 9.2 (AV:L/AC:L/PR:N/UI:N/S:C/C:H/I:L/A:H), highlighting its critical severity due to high impact on confidentiality, availability, and scope change.
A local attacker with no privileges required can exploit this vulnerability with low complexity and no user interaction. Successful exploitation enables execution of arbitrary commands with root privileges inside the container, potentially leading to container escape and unauthorized modifications to the underlying infrastructure.
The vulnerability is addressed in version 1.0.1 through strict input sanitization, secure delimiters in entrypoint.sh, enforcement of a non-root user (appuser) in the Dockerfile, and mandatory security quality gates. Details are available in the GitHub security advisory (GHSA-chh5-w73q-4gmm) and release notes at the Security tag.

Mitigating Controls (NIST 800-53 r5) AI
Account management directly governs assignment and tracking of privileges so proper implementation stops the weakness from being introduced.
Requiring explicit access-control decisions ensures privileges are evaluated rather than assumed or omitted.
Access enforcement applies the correct privilege checks at every request, structurally preventing unintended spheres of control.
Separation of duties constrains how privileges may be assigned, reducing the chance of overly broad actor control.
Least privilege directly requires that only the minimum necessary authorizations are granted, structurally eliminating execution with unnecessary privileges.
Developer testing and evaluation can discover missing or incorrect command sanitization during development.

PR.AA-05 directly enforces least privilege so largely eliminates CWE-250 at design time, yet the weakness can still arise from runtime escalation paths, third-party code, or misapplied role definitions outside this single control.
PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
PR.AA-01 supplies credential/identity lifecycle support that can reduce some privilege-assignment errors but does not itself assign, modify, or check privileges, leaving most of CWE-269's risk unaddressed.
Config baselines and default reviews can enforce some privilege-related settings (one facet) but do not address code-level assignment/tracking logic that defines CWE-269.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
PR.PS-05 can partially limit exploitability of some privilege issues via execution restrictions, but does not address the core design/implementation flaws of CWE-269 at all.

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.
Requiring explicit justification and time-limited grants discourages the routine allocation of unnecessary privileges that would otherwise allow execution with more rights than required.
Restricting privileged utilities to the fewest trusted users and requiring explicit authorization directly stops developers or operators from embedding or invoking code that runs with unnecessary elevated rights.
Mandating separate non-privileged identities for routine work and restricting privileged accounts to administrative tasks reduces the chance that everyday operations run with unnecessary elevated rights.
Security testing and code review target insecure use of operating-system command interfaces, catching command-injection flaws introduced during development.
Dynamic techniques that grant the minimum necessary rights for a given time window and revoke them afterward reduce the window in which excessive or unnecessary privileges can be exploited.
The control explicitly calls for minimizing privileged identities and disabling unnecessary accounts, thereby reducing the number of processes that run with unnecessary privileges.
