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
A vulnerability was found in BoyunCMS up to 1.4.20. It has been rated as critical. This issue affects some unknown processing of the file /application/pay/controller/Index.php of the component curl. The manipulation leads to server-side request forgery. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

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 · high confidence

BoyunCMS versions up to 1.4.20 contain a server-side request forgery (SSRF) vulnerability in the /application/pay/controller/Index.php file via the curl component. The vulnerability allows remote attackers to induce the server to make arbitrary requests to internal or external resources by manipulating input to the curl functionality.

MitigationImplement strict URL validation and allowlisting for all outbound requests in the affected curl component, restricting requests to trusted domains only and blocking requests to internal network resources.

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. Locate Boyuncms installation
    Search for the presence of the /application/pay/controller/Index.php file in the web root directory, or look for Boyuncms-specific directory structure.
    Affected if The file /application/pay/controller/Index.php exists in the web application directory.
  2. Determine installed Boyuncms version
    Check for a version file or metadata in the Boyuncms installation (such as a version.php, composer.json, or README file). Compare the found version against the affected range of 1.4 through 1.4.20.
    Affected if The installed version is 1.4 or higher, up to and including 1.4.20.
  3. Verify the vulnerable curl component exists
    Examine the /application/pay/controller/Index.php file and confirm it contains curl functionality (look for curl_init, curl_exec, or similar curl-related PHP functions).
    Affected if The Index.php file in the pay controller contains curl request handling code.
  4. Check if pay module is accessible
    Determine whether the pay controller is accessible via web requests by checking routing configuration or attempting to access the /pay or /index.php/pay endpoint.
    Affected if The pay module is routable and accessible via HTTP requests without authentication.

A system is affected if Boyuncms version 1.4 through 1.4.20 is installed, the vulnerable /application/pay/controller/Index.php file with curl functionality exists, and the pay module is accessible.
