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
Improper Control of Generation of Code ('Code Injection') vulnerability in Brainstorm Force Astra Pro.This issue affects Astra Pro: from n/a through 4.3.1.

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 code injection vulnerability in the Astra Pro WordPress theme where user-supplied input is being used in code generation without proper validation or sanitization. An attacker could potentially inject malicious PHP code that gets executed on the server, leading to remote code execution and complete site compromise.

MitigationUpdate Astra Pro to the latest version (beyond 4.3.1) to receive the vendor patch. If immediate updating is not feasible, implement a WAF rule as a temporary measure and restrict user access to minimize the attack surface.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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 Astra Pro theme version
    Navigate to WordPress dashboard > Appearance > Themes and locate the Astra theme. Click on the theme to view its details, or check the style.css file in wp-content/themes/astra/ for the 'Version' header.
    Affected if The displayed version is 4.3.1 or any earlier version.
  2. Verify code generation feature status
    Check if the Astra Pro Custom Layouts or Dynamic Content features are active. Navigate to Astra Pro > Custom Layouts in the WordPress admin panel and review any layouts that execute PHP code.
    Affected if Custom Layouts with PHP execution enabled are present and accessible to untrusted users.
  3. Inspect theme files for code generation logic
    Examine wp-content/themes/astra-pro/inc/dynamic-content.php or similar files that handle dynamic code generation. Look for functions that process user input into eval(), exec(), or file_put_contents() operations.
    Affected if User-supplied input fields (such as custom layout code or dynamic data) are being passed to code execution functions without sanitization.
  4. Review user role permissions
    Go to WordPress admin > Users and audit which roles have access to Astra Pro settings, Custom Layouts, or Elementor/BB editor integrations that could inject code.
    Affected if Users with Contributor, Author, or Editor roles (or any untrusted role) have access to code-related theme features.
  5. Check for unauthorized custom layouts
    Query the wp_postmeta table for post_type = 'astra-advanced-hook' or 'astra-custom-layout', or review entries in the Astra Pro Custom Layouts admin panel for suspicious PHP code submissions.
    Affected if Unexpected or malicious PHP code entries exist in custom layout definitions.

You are affected if the Astra Pro version is 4.3.1 or lower AND untrusted users can access or modify code generation features such as Custom Layouts or dynamic hooks.

dbcve · scoped
Upgrade available Upgrade to a release after 4.3.1
Interim mitigation

Update Astra Pro to the latest version (beyond 4.3.1) to receive the vendor patch. If immediate updating is not feasible, implement a WAF rule as a temporary measure and restrict user access to minimize the attack surface.

Recommended fix Moderate confidence

Astra Pro version 4.3.2 or later (verify the exact version from official release notes)

  1. Check the official Astra theme changelog or Brainstorm Force release notes for version 4.3.2 or higher
  2. Navigate to the WordPress admin dashboard under Appearance > Themes
  3. Backup the current website before performing any updates
  4. Update Astra Pro theme to the latest available version that includes the security fix
  5. Verify the update was successful and the website functions normally
  6. Check patchstack.com or the official Brainstorm Force security advisory for the specific fixed version number
Caveat Review the theme changelog for any breaking changes between 4.3.1 and the fixed version before upgrading in production environments
