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 Ultimate Blogroll plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.5.2. This is due to missing or incorrect nonce validation on a function. This makes it possible for unauthenticated attackers to update settings and inject malicious web scripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.

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 Ultimate Blogroll WordPress plugin versions up to 2.5.2 lack proper nonce validation on certain functions, allowing unauthenticated attackers to craft forged requests that can modify plugin settings and inject malicious scripts via Cross-Site Request Forgery. The attack requires tricking an authenticated administrator into clicking a malicious link.

MitigationUpdate the plugin to the latest version once available, and warn administrators to verify link authenticity before clicking to mitigate CSRF attacks.
