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 determined in SourceCodester SEO Meta Tag Extractor 1.0. This vulnerability affects the function get_headers of the file /index.php. This manipulation of the argument url causes server-side request forgery. It is possible to initiate the attack remotely. The exploit has been publicly disclosed and may be utilized.

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

This is a Server-Side Request Forgery (SSRF) vulnerability in SourceCodester SEO Meta Tag Extractor 1.0. The application uses the PHP get_headers() function in /index.php to fetch HTTP headers from a user-supplied URL passed via the 'url' parameter. Because there is no validation of this input, an attacker can manipulate the URL to cause the server to make requests to internal infrastructure, cloud metadata services, or other internal resources that should not be exposed.

MitigationImplement strict allowlist-based validation for the URL parameter, ensuring only approved domain patterns or explicitly permitted hosts can be requested. Additionally, restrict outbound connections to prevent access to internal networks (e.g., 127.0.0.1, 169.254.169.254, 10.x.x.x, 192.168.x.x).

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. Confirm SEO Meta Tag Extractor is installed
    Locate the web application directory and identify the installed version by checking version files, headers, or application metadata
    Affected if The application is running and version 1.0 is confirmed
  2. Verify the vulnerable endpoint exists
    Check for the presence of /index.php in the web root and confirm the 'url' parameter is accepted via GET or POST request
    Affected if The index.php file exists and accepts a 'url' parameter
  3. Inspect the get_headers implementation
    Open /index.php and locate the get_headers function call that processes the 'url' parameter. Search for code that passes user input directly to this function without validation
    Affected if The code uses get_headers with the 'url' parameter without sanitization or allowlist validation
  4. Test for SSRF accessibility
    Submit a crafted 'url' parameter value pointing to an internal resource (e.g., http://127.0.0.1 or an internal IP) and observe if the application makes a request to that endpoint
    Affected if The application successfully fetches or attempts to fetch the provided internal URL, indicating no protection is in place

If the application is SourceCodester SEO Meta Tag Extractor version 1.0, the index.php file contains the get_headers function using the 'url' parameter without input validation, and the endpoint is accessible, the environment is affected by this SSRF vulnerability.

Mitigation

Implement strict allowlist-based validation for the URL parameter, ensuring only approved domain patterns or explicitly permitted hosts can be requested. Additionally, restrict outbound connections to prevent access to internal networks (e.g., 127.0.0.1, 169.254.169.254, 10.x.x.x, 192.168.x.x).
