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 NewsBlogger theme for WordPress is vulnerable to arbitrary file uploads due to a missing capability check on the newsblogger_install_and_activate_plugin() function in all versions up to, and including, 0.2.5.1. This makes it possible for authenticated attackers, with subscriber-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

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

The NewsBlogger WordPress theme (versions up to 0.2.5.1) contains a function called newsblogger_install_and_activate_plugin that lacks proper capability validation. This allows any authenticated user with subscriber-level permissions (the lowest WordPress role) to upload and execute arbitrary files on the server, leading to potential remote code execution.

MitigationUpdate the NewsBlogger theme to the latest version immediately. If an update is unavailable, remove the vulnerable function or add a capability check requiring 'manage_options' permissions before allowing plugin installations.

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 NewsBlogger theme is installed
    In WordPress admin dashboard, go to Appearance > Themes to see if NewsBlogger theme appears in the installed themes list. Alternatively, check the theme directory at wp-content/themes/newsblogger for existence.
    Affected if The NewsBlogger theme directory exists in the WordPress installation
  2. Determine installed NewsBlogger version
    If the theme is installed, check the style.css file in wp-content/themes/newsblogger/ for the 'Version:' header in the file comment block at the top. Compare this version number to 0.2.5.2.
    Affected if The reported version is below 0.2.5.2 (for example: 0.2.5, 0.2.5.1, or any version number less than 0.2.5.2)
  3. Locate the vulnerable function in theme files
    In the theme directory, search for the string 'newsblogger_install_and_activate_plugin' in PHP files, typically found in functions.php or a dedicated include file within the theme folder.
    Affected if The function named newsblogger_install_and_activate_plugin exists in any PHP file within the theme
  4. Verify subscriber-level access can trigger the function
    Test by creating a test account with only the Subscriber role and attempting to access the function endpoint. In WordPress, the function is hooked to an action that may be accessible via AJAX or direct URL access without elevated permissions.
    Affected if The function is hooked to an action (such as wp_ajax_) that does not verify user capabilities before execution, allowing subscriber-level users to reach it

A user is affected if the NewsBlogger theme version is below 0.2.5.2 AND the newsblogger_install_and_activate_plugin function exists and is accessible to users with subscriber-level permissions.
