CVE-2025-23916
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 Nuanced Media WP Meetup wp-meetup allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects WP Meetup: from n/a through <= 2.3.0.
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 confidenceThe WP Meetup plugin for WordPress contains a missing authorization vulnerability where access control checks are incorrectly configured or missing entirely. This allows authenticated users with insufficient privileges to access administrative or sensitive meeting management functions that should require higher capability levels. The vulnerability stems from improper implementation of WordPress capability checks (e.g., current_user_can()) before executing sensitive 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.
-
Confirm WP Meetup plugin is installedLog into WordPress admin and navigate to Plugins > Installed Plugins, or check the /wp-content/plugins/ directory for the wp-meetup folderAffected if The plugin is present in the environment
-
Identify the installed plugin versionIn WordPress admin, find WP Meetup in the plugins list and note the version number displayed under the plugin name, or open the main plugin file (e.g., wp-meetup.php) and look for the 'Version' header commentAffected if The version is unknown or cannot be determined from the plugin header
-
Verify the plugin is activeIn WordPress admin > Plugins, check if WP Meetup shows as 'Active' under the plugin status columnAffected if The plugin is active and running on the site
-
Inspect for proper capability checks in plugin codeExamine the main plugin PHP files for presence of current_user_can() calls before sensitive operations (e.g., meeting creation, deletion, user role assignment). Check if capability checks use appropriate capabilities like 'manage_options' or 'organize_meetings' before executing administrative functionsAffected if No current_user_can() checks exist, or checks use insufficient capabilities (e.g., 'edit_posts' for admin functions)
-
Test for authorization bypassCreate or use a WordPress user account with a low-privilege role (e.g., Subscriber) and attempt to access WP Meetup administrative functions directly via URL (e.g., admin pages for creating/editing meetups)Affected if A low-privilege user can access or modify meetup data that should require administrator or organizer privileges
The environment is affected if the WP Meetup plugin is active, lacks proper current_user_can() capability verification before sensitive meetup operations, or allows users with subscriber/contributor roles to access administrative meeting management functions.

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 dataApply the latest plugin update which should include proper authorization checks, or manually add WordPress capability verification (current_user_can()) with appropriate roles (administrator, organizer) before any sensitive meetup operations.
