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.

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 Efficient Scripts Microblog Poster <= 2.1.6 allows attackers to inject malicious JavaScript code (Stored XSS) into the application by tricking authenticated administrators into unknowingly submitting crafted requests, such as maliciously crafted blog post or social media publishing configurations.

MitigationApply the vendor's latest security patch (version 2.1.7 or later) and implement anti-CSRF tokens with SameSite cookie attributes on all state-changing form submissions to prevent unauthorized requests.

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 the installed version of Microblog Poster
    Locate the plugin/theme version information in the product's main file, admin dashboard 'About' page, or version metadata file. Common locations include a 'version' constant in the primary PHP file or a manifest/config file.
    Affected if The installed version is 2.1.6 or lower.
  2. Locate the admin submission forms for blog posts and social media configurations
    Access the admin panel and navigate to the sections for creating/editing blog posts and social media publishing configurations. Identify the HTML form elements that handle these state-changing submissions.
    Affected if Forms exist for blog post or social media publishing configurations without visible evidence of anti-CSRF token fields.
  3. Inspect the form HTML for anti-CSRF token presence
    View the page source of the blog post and social media configuration forms. Look for hidden input fields containing unique tokens (e.g., 'csrf_token', 'nonce', '_wpnonce') or check if the form submission includes token parameters via developer tools.
    Affected if The forms do not include any hidden anti-CSRF token fields in the HTML markup.
  4. Check session cookie attributes for SameSite flag
    Log into the admin panel and use browser developer tools (Application tab > Cookies) to inspect the session cookie. Verify if the SameSite attribute is set to 'Strict' or 'Lax', or if it is missing/absent.
    Affected if The session cookie lacks the SameSite attribute or is set to 'None' without Secure flag.
  5. Test form submission without token to confirm vulnerability
    Use a tool like Burp Suite or curl to send a crafted POST request to the form endpoint without the anti-CSRF token. Observe if the request is processed successfully.
    Affected if The form accepts and processes the submission without requiring a valid anti-CSRF token.

You are affected if the installed version is 2.1.6 or lower AND the admin forms for blog posts or social media configurations lack anti-CSRF token protection AND the session cookies lack proper SameSite attributes.
