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 · uneditedCross-Site Request Forgery (CSRF) vulnerability in Palasthotel (in person: Edward Bock) Use Memcached plugin <= 1.0.4 versions.
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 confidenceCross-Site Request Forgery (CSRF) vulnerability in the Use Memcached WordPress plugin versions 1.0.4 and below. Attackers can potentially trick authenticated administrators into unknowingly executing unintended actions via maliciously crafted requests, as the plugin lacks proper anti-CSRF token validation on state-changing operations.

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 checksWork through these to decide whether this CVE applies to you.
-
Locate the Use Memcached plugin installationCheck the WordPress plugins directory at wp-content/plugins/ for a folder named 'use-memcached' or 'palasthotel-use-memcached'. Also check via WordPress admin under Plugins > Installed Plugins.Affected if The plugin folder exists and the plugin is active in the WordPress site.
-
Determine the installed plugin versionIf the plugin is installed, view the main plugin file (usually index.php or use-memcached.php) and look for the version header comment at the top of the file, or check the version displayed in the WordPress admin plugins list.Affected if The reported version is 1.0.4 or lower.
-
Identify state-changing operations in the pluginExamine the plugin source code for any forms (HTML <form> tags) and AJAX actions (wp_ajax_ hooks) that perform server-side operations such as saving settings, clearing cache, modifying configuration, or any action that changes the plugin or site state.Affected if The plugin contains forms or AJAX handlers that perform state-changing operations.
-
Verify absence of nonce validationReview the identified form handlers and AJAX callbacks in the plugin code. Search for the presence of wp_verify_nonce, check_admin_referer, or nonces in form fields. Check if these validation functions are called before processing any state-changing requests.Affected if State-changing forms or AJAX actions lack nonce verification calls, meaning they do not validate anti-CSRF tokens before executing operations.
You are affected if the Use Memcached plugin versions 1.0.4 or lower is installed and active, and its forms or AJAX actions handling state changes do not implement WordPress nonce validation.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate the Use Memcached plugin to version greater than 1.0.4. If no update is available, disable the plugin until a patched version is released. The fix requires implementing WordPress nonces (anti-CSRF tokens) on all forms and AJAX actions that perform server-side operations.
