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

A Code Injection vulnerability exists in the Themeisle Woody ad snippets (insert-php) WordPress plugin versions through 2.7.1. The vulnerability allows attackers to inject and execute arbitrary PHP code on the server, potentially leading to complete site compromise, data theft, or malware deployment.

MitigationUpdate Woody ad snippets to the latest patched version immediately. If no patch is available, disable the plugin, revoke administrative access from untrusted users, and review server access logs for signs of exploitation.

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. Verify Woody ad snippets plugin is installed
    Log in to WordPress admin dashboard, navigate to Plugins > Installed Plugins, and look for 'Woody ad snippets' in the list of active plugins.
    Affected if The plugin appears in the installed plugins list and is activated.
  2. Determine plugin version
    In the Plugins list, click on 'Woody ad snippets' to view the plugin details, or check the plugin file header in wp-content/plugins/woody-ad-snippets/includes/plugin.php for the Version comment.
    Affected if The installed version matches any version prior to the patched release (compare against the vendor's security advisory for the fixed version number).
  3. Confirm insert-php feature is active
    Navigate to the plugin settings in WordPress admin (Woody ad snippets > Snippets) and check if any snippets with PHP code are present, or inspect the wp_woody_snippets postmeta table in the database for postmeta_key values containing 'php_code' or similar.
    Affected if PHP snippets exist in the plugin or the insert-php feature is enabled in the plugin settings.
  4. Inspect for unauthorized PHP code injection
    Access the WordPress database via phpMyAdmin or command line, query the wp_posts table for posts with post_type 'woody_snippet' and examine the post_content field for suspicious or unknown PHP code blocks.
    Affected if The post_content contains unfamiliar or malicious PHP code that was not authored by legitimate administrators.

A user is affected if the Woody ad snippets plugin with insert-php functionality is installed and the version is prior to the vendor's patched release, or if unauthorized PHP code is found in the snippet database records.
