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 cybio GravatarLocalCache gravatarlocalcache allows Cross Site Request Forgery.This issue affects GravatarLocalCache: from n/a through <= 1.1.2.
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 GravatarLocalCache WordPress plugin versions up to 1.1.2 allows remote attackers to induce authenticated users to perform unintended actions by tricking them into submitting malicious 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 checksWork through these to decide whether this CVE applies to you.
-
Verify GravatarLocalCache plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'GravatarLocalCache' or check the plugin files in wp-content/plugins/ directoryAffected if Plugin is installed and version is 1.1.2 or lower
-
Identify plugin version numberCheck the plugin header in gravatar-local-cache.php or the version in the plugin's readme.txt fileAffected if Version is 1.1.2 or any version up to and including 1.1.2
-
Locate state-changing operations in plugin codeSearch plugin PHP files for form tags, admin_post_ hooks, wp_ajax_ hooks, or any handler that modifies data or settingsAffected if The plugin contains forms or AJAX endpoints that modify settings or cache data without requiring user interaction beyond authentication
-
Check if nonces are verified on state-changing actionsSearch plugin code for wp_verify_nonce, check_ajax_referer, check_admin_referer, or wp_create_nonce function calls near the identified state-changing handlersAffected if State-changing operations lack nonce verification or use a nonce that can be bypassed
-
Verify Origin or Referer header validationSearch plugin code for checks of $_SERVER['HTTP_ORIGIN'] or $_SERVER['HTTP_REFERER'] variables before processing requestsAffected if No Origin or Referer header validation is performed on state-changing requests
User is affected if GravatarLocalCache plugin version 1.1.2 or lower is installed AND the plugin performs state-changing operations without proper nonce verification or Origin/Referer header 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 dataImplement anti-CSRF tokens (nonces) on all state-changing operations and validate the Origin/Referer headers to prevent cross-site request forgery attacks.
