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

Cross-Site Request Forgery (CSRF) vulnerability in the Category Specific RSS feed Subscription WordPress plugin affecting versions 2.1 and below. The vulnerability allows attackers to induce authenticated users to perform unintended actions via malicious requests.

MitigationImplement WordPress nonces (anti-CSRF tokens) on all state-changing form actions and AJAX endpoints within the plugin, and verify the nonce validity server-side before processing any request.

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 the plugin is installed
    Log into the WordPress admin dashboard and navigate to Plugins > Installed Plugins. Look for 'Tipsandtricks HQ Category Specific RSS Feed Subscription' in the list of active or installed plugins.
    Affected if the plugin appears in the installed plugins list
  2. Check the installed version
    In the Plugins page, locate the plugin and view the version number displayed beneath the plugin name. Alternatively, inspect the main plugin file header in /wp-content/plugins/category-specific-rss-feed-subscription/ for the 'Version' field.
    Affected if the version number is 2.1 or lower (below 2.2)
  3. Inspect plugin for nonce implementation
    Examine the plugin PHP files (particularly form handlers and AJAX endpoints) for the presence of wp_verify_nonce() or check_admin_referer() calls. Search for 'nonce' or '_wpnonce' within the plugin directory.
    Affected if state-changing forms or AJAX actions lack nonce verification logic (wp_verify_nonce or check_admin_referer)
  4. Verify nonce usage on form actions
    Review the plugin templates or PHP files that generate HTML forms. Check if generated forms include a hidden nonce field (e.g., wp_create_nonce or wp_nonce_field) in the form markup.
    Affected if forms do not contain nonce fields

A user is affected if the plugin is installed with version 2.1 or below and the plugin's forms or AJAX endpoints are missing nonce verification, allowing CSRF attacks to succeed.
