Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
The system exposes several endpoints, typically including "/int/" in their path, that should be restricted to internal services, but are instead publicly accessible without authentication to any host able to reach the application server on port 443/tcp.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Internal API endpoints containing '/int/' in their URL path are exposed to the public internet without authentication. Any host that can reach the application's HTTPS port (443/tcp) can access these endpoints that should be restricted to internal services only, potentially exposing sensitive functionality or data.

MitigationImplement network-level access controls (firewall rules, VPC security groups, or WAF rules) to restrict access to /int/ paths to authorized internal IP ranges, or add proper authentication/authorization checks at the application layer for these endpoints.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify if the application has /int/ path endpoints
    Review application routing configuration, API documentation, or perform web crawling to discover endpoints containing '/int/' in their URL paths. Check routes.js, api.yaml, or similar routing definitions.
    Affected if The application exposes any endpoints with '/int/' in the URL path that should be restricted to internal services.
  2. Test unauthenticated access to /int/ endpoints from external network
    Send HTTP/HTTPS requests to discovered /int/ endpoints without providing any authentication credentials. Use a tool like curl or a network scanner from outside the internal network.
    Affected if The /int/ endpoints respond with valid data or acceptable HTTP responses (not 401/403) when accessed without authentication.
  3. Verify network-level access controls for /int/ paths
    Review firewall rules, VPC security groups, WAF configurations, or reverse proxy settings to determine if access to /int/ paths is restricted to specific internal IP ranges or authorized networks.
    Affected if No network-level restrictions exist that limit /int/ endpoint access to internal IP addresses only.
  4. Check application-layer authentication for internal endpoints
    Examine the application's authentication and authorization middleware, route guards, or API security configuration to verify that /int/ paths require valid authentication or are explicitly blocked for external requests.
    Affected if The application does not enforce authentication, authorization, or IP-based restrictions for /int/ endpoint access.

The environment is affected if the application exposes /int/ endpoints that are accessible from external networks without requiring authentication or network-level access controls.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Implement network-level access controls (firewall rules, VPC security groups, or WAF rules) to restrict access to /int/ paths to authorized internal IP ranges, or add proper authentication/authorization checks at the application layer for these endpoints.
