Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates CVE-2026-7237 by requiring timely patching to version 1.1.0, which resolves the path traversal flaw via commit c4d23592ae5fb59cfeefc4641e6826f8ac89b9c6.

SI-10 Information Input Validation good match

prevent

Validates the manipulated file_path argument in the write-to-file Tool to block path traversal sequences like '../', preventing unauthorized file access outside intended directories.

AC-3 Access Enforcement partial match

prevent

Enforces logical access controls on file system resources to restrict unauthorized reading or writing resulting from path traversal exploitation.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

attack.mitre.org →

T1005 Data from Local System Collection

Adversaries may search local system sources, such as file systems, configuration files, local databases, virtual machine files, or process memory, to find files of interest and sensitive data prior to Exfiltration.

attack.mitre.org →

T1105 Ingress Tool Transfer Command And Control

Adversaries may transfer tools or other files from an external system into a compromised environment.

attack.mitre.org →

Why these techniques?

Path traversal in remote write-to-file component (AV:N, no auth) directly enables remote exploitation of public-facing app (T1190), arbitrary local file reads (T1005), and writing/transferring files into the environment (T1105).

NVD Description

A vulnerability was detected in AgiFlow scaffold-mcp up to 1.0.27. Affected by this issue is some unknown functionality of the file packages/scaffold-mcp/src/server/index.ts of the component write-to-file Tool. The manipulation of the argument file_path results in path traversal. The attack may…

be launched remotely. The exploit is now public and may be used. Upgrading to version 1.1.0 can resolve this issue. The patch is identified as c4d23592ae5fb59cfeefc4641e6826f8ac89b9c6. You should upgrade the affected component.

Deeper analysisAI

CVE-2026-7237 is a path traversal vulnerability (CWE-22) in AgiFlow scaffold-mcp versions up to 1.0.27. The issue affects an unknown functionality within the write-to-file Tool component, specifically in the file packages/scaffold-mcp/src/server/index.ts. Published on 2026-04-28, it carries a CVSS v3.1 base score of 7.3 (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L).

Remote attackers can exploit this vulnerability by manipulating the file_path argument, requiring no authentication or user interaction. Successful exploitation enables limited impacts to confidentiality, integrity, and availability, such as unauthorized reading or writing outside intended directories. The exploit is publicly available.

Advisories recommend upgrading to version 1.1.0, which resolves the issue via patch commit c4d23592ae5fb59cfeefc4641e6826f8ac89b9c6.
