CVE-2024-2217 — gaizhenbiao/chuanhuchatgpt is vulnerable to improper access control, allowing unauthorized access to the `config.json` file

High CVSS 7.5

gaizhenbiao/chuanhuchatgpt is vulnerable to improper access control, allowing unauthorized access to the `config.json` file. This vulnerability is present in both authenticated and unauthenticated versions of the application, enabling attackers to obtain sensitive information such as API keys (`openai_api_key`, `google_palm_api_key`, `xmchat_api_key`, etc.), configuration details, and user credentials. The issue stems from the application's handling of HTTP requests for the `config.json` file, which does not properly restrict access based on user authentication.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
