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 checksWork through these to decide whether this CVE applies to you.
-
Identify if Feehi CMS is installedCheck your web server for Feehi CMS by looking for its typical installation directories or admin login pages at common paths like /admin or /index.php?r=adminAffected if Feehi CMS is present on the server
-
Determine the installed Feehi CMS versionLocate the version information in the CMS installation, typically found in a version file, composer.json, or the admin dashboard about page. Compare your version against the affected range (versions up to 2.1.1)Affected if The installed version is 2.1.1 or any earlier version
-
Verify the REST API endpoint is exposedCheck if your web server configuration allows access to the /api/articles path. Review your web server access logs for any requests to /api/articlesAffected if The /api/articles endpoint is reachable from the network
-
Test for unauthenticated API accessSend an HTTP GET request to /api/articles (or /api/articles/index or similar) without providing any authentication credentials (no API key, token, or session cookie)Affected if The endpoint returns a successful response with data instead of rejecting the request with an authentication error (401 or 403)
You are affected if Feehi CMS version 2.1.1 or earlier is installed and the /api/articles endpoint returns API data without requiring authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUntil an official patch is released, implement network-level access controls (firewall/allowlisting) to restrict access to the /api/articles endpoint, or deploy a reverse proxy with authentication enforcement in front of the API.
