CVE-2023-32127
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 · uneditedMissing Authorization vulnerability in Daniel Powney Multi Rating allows Functionality Misuse.This issue affects Multi Rating: from n/a through 5.0.6.
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 confidenceMissing Authorization vulnerability in the Multi Rating WordPress plugin allows functionality misuse due to absent or insufficient permission checks. This could allow lower-privileged users (such as subscribers or unauthenticated users in some cases) to access or manipulate rating functionality they should not have access to.

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 Multi Rating plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Multi Rating' or check the plugins directory (wp-content/plugins/multi-rating/) for the plugin files. Check the plugin header in the main PHP file for the version number.Affected if Multi Rating plugin is installed and the version falls within the vulnerable range (check against available security advisories for specific versions).
-
Identify AJAX handlers in the pluginSearch the plugin directory for add_action('wp_ajax_...) calls and add_action('wp_ajax_nopriv_...) calls. These are typically found in the main plugin file or separate AJAX handler files.Affected if The plugin contains AJAX handlers, especially wp_ajax_nopriv_ handlers which allow unauthenticated access.
-
Inspect AJAX handlers for capability checksOpen each AJAX handler function and look for current_user_can() calls before performing sensitive operations. Check if the handler verifies user permissions.Affected if AJAX handlers lack current_user_can() checks or perform privileged operations without verifying user capabilities.
-
Inspect admin functions for authorization checksReview admin menu callbacks and admin_init hooks for missing current_user_can() checks. Look for functions that modify rating data, settings, or plugin options.Affected if Admin functions lack proper capability checks and allow lower-privileged users to perform actions reserved for administrators.
-
Check for nonce verification in sensitive functionsSearch for wp_verify_nonce(), check_ajax_referer(), or wp_nonce_field() calls within AJAX handlers and form processing functions.Affected if Sensitive functions lack nonce verification, allowing CSRF attacks to exploit authorization gaps.
A user is affected if the Multi Rating plugin is installed and its AJAX handlers or admin functions lack proper capability checks (current_user_can()) and nonce verification, allowing subscribers or unauthenticated users to access or manipulate rating functionality they should not access.

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 Multi Rating plugin to the latest version when available. Until then, review all AJAX handlers and admin functions to add proper capability checks (current_user_can()) and nonce verification.
