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 Easy Post Submission WordPress plugin (versions <= 2.4.0) allows attackers to bypass access control security levels. The plugin fails to properly validate user permissions before allowing post submission actions, likely enabling unauthenticated or lower-privileged users to create or modify content 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.
-
Check Easy Post Submission plugin versionNavigate to WordPress admin > Plugins > Installed Plugins, locate 'Easy Post Submission' and read the version number displayed under the plugin nameAffected if The displayed version is 2.4.0 or lower
-
Verify plugin is activeIn the same plugins list, confirm the 'Easy Post Submission' plugin has an 'Active' status indicatorAffected if The plugin is active and the version is 2.4.0 or lower
-
Inspect plugin submission handler for capability checksAccess the plugin directory via file manager or FTP (wp-content/plugins/easy-post-submission or similar), locate the main PHP file handling form submissions, and search for 'current_user_can' or 'current_user' function calls near the submission processing codeAffected if No 'current_user_can' capability check is found before post creation/modification logic, or the check is missing entirely
-
Check submission endpoints for nonce validationIn the same plugin PHP files, locate form action handlers and search for 'wp_verify_nonce' or 'check_admin_referer' function calls that validate the request originAffected if No nonce validation is present on the post submission handler, or nonce checks are absent before processing the submitted data
-
Test if anonymous users can access submission functionalityIf the site has a public-facing submission form provided by this plugin, attempt to submit a post without logging in or with a low-privilege user account (subscriber level)Affected if The submission is accepted and a post is created without requiring authentication or elevated privileges
Your environment is affected if the Easy Post Submission plugin version is 2.4.0 or lower and the plugin is active, with no capability checks or nonce validation found in the submission handling code.

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 to the latest version of Easy Post Submission plugin which implements proper authorization checks, or implement role-based capability checks (current_user_can) and nonce validation on all post submission endpoints.
