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 Vikinghammer Tweet WordPress plugin through 0.2.4 does not have CSRF check in some places, and is missing sanitisation as well as escaping, which could allow attackers to make logged in admin add Stored XSS payloads via a CSRF attack.

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

The Vikinghammer Tweet WordPress plugin through version 0.2.4 lacks CSRF protection in certain functions and fails to properly sanitize user input and escape output. This allows authenticated administrators to be tricked via CSRF into submitting malicious JavaScript payloads that get stored in the database and execute when other users view the affected content, resulting in stored XSS.

MitigationUpdate to a patched version of the plugin if available. Until then, implement CSRF tokens (nonces) on state-changing operations and apply proper sanitization (e.g., sanitize_text_field) and output escaping (e.g., esc_html, esc_attr) to all user-supplied data before rendering.

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 plugin installation and version
    Navigate to WordPress admin > Plugins and locate 'Vikinghammer Tweet' or 'Seanschulte Vikinghammer Tweet', or inspect the plugin directory at /wp-content/plugins/ for a folder named 'vikinghammer-tweet' or similar and read the main PHP file header for the Version field
    Affected if The plugin is installed and the version is 0.2.4 or lower
  2. Verify plugin is active
    Check the WordPress admin Plugins page to confirm the Vikinghammer Tweet plugin is currently activated
    Affected if The plugin is active, as inactive plugins cannot be exploited through this stored XSS vector
  3. Inspect plugin code for sanitization
    Review the main plugin PHP file(s) for use of sanitization functions like sanitize_text_field, sanitize_email, or esc_html/esc_attr when handling user input
    Affected if The code lacks proper sanitization (sanitize_text_field etc.) and escaping (esc_html, esc_attr) on user-supplied data before output
  4. Check database for stored XSS payloads
    Query the WordPress database (wp_posts, wp_postmeta, or any custom tables created by the plugin) for suspicious script tags, event handlers, or encoded JavaScript payloads that may have been injected via CSRF
    Affected if Malicious JavaScript payloads are found stored in the database associated with the plugin

You are affected if the Vikinghammer Tweet plugin version 0.2.4 or lower is installed and active, and the plugin code or database contains unsanitized user input that could execute as JavaScript in a user's browser.

dbcve · scoped
Upgrade available Upgrade to a release after 0.2.4
Interim mitigation

Update to a patched version of the plugin if available. Until then, implement CSRF tokens (nonces) on state-changing operations and apply proper sanitization (e.g., sanitize_text_field) and output escaping (e.g., esc_html, esc_attr) to all user-supplied data before rendering.

Recommended fix Moderate confidence

A fixed version higher than 0.2.4 (verify availability at wordpress.org/plugins/vikinghammer-tweet or contact the developer)

  1. Check the WordPress plugin repository or contact the plugin developer to confirm if a fixed version of Vikinghammer Tweet is available
  2. If a fixed version is available, navigate to Plugins > Installed Plugins in WordPress admin
  3. Deactivate the vulnerable Vikinghammer Tweet plugin
  4. Delete the vulnerable plugin files
  5. Install and activate the fixed version of the plugin
  6. Verify the fix by checking that CSRF protection is now properly implemented
  7. Test that the plugin functionality works as expected with the new version
  8. If no fixed version is available, consider removing the plugin and finding an alternative Twitter/tweet embed plugin with active security support
Caveat Review plugin settings after upgrade as minor configuration changes may occur
