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 inkthemes WP Mailgun SMTP wp-mailgun-smtp allows Accessing Functionality Not Properly Constrained by ACLs.This issue affects WP Mailgun SMTP: from n/a through <= 1.0.7.
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 WP Mailgun SMTP WordPress plugin allows unauthenticated or unauthorized users to access administrative functionality that should be restricted by Access Control Lists (ACLs). The plugin fails to properly validate user capabilities before executing certain actions, enabling privilege escalation or unauthorized configuration changes.

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 Mailgun SMTP plugin is installedNavigate to WordPress admin dashboard > Plugins and locate WP Mailgun SMTP in the installed plugins list. Note its activation status.Affected if Plugin is installed and active in WordPress
-
Check installed plugin versionIn the Plugins list, click on WP Mailgun SMTP to view the version number, or read the plugin header from the main PHP file in /wp-content/plugins/mailgun-smtp/Affected if Version is older than the patched version released for this CVE
-
Identify admin action handlers in plugin codeExamine the main plugin PHP file for hooks that handle admin actions (e.g., admin_init, wp_ajax_, init handlers with $_POST or $_GET parameters). Search for function calls that modify settings or configurations.Affected if Plugin contains admin action handlers that process configuration changes or privileged operations
-
Verify capability checks exist on admin functionsReview identified admin action handlers and check whether they include current_user_can() calls or similar WordPress capability validation before executing the action. Look for nonce verification as well.Affected if Admin functions lack current_user_can() checks and allow execution without proper authorization
-
Test unauthorized access to plugin functionsAttempt to access plugin admin pages or submit plugin-related requests while logged out or as a subscriber-level user. Observe whether actions execute without being blocked.Affected if Actions execute without proper authorization or capability verification
If WP Mailgun SMTP is installed and its administrative functions lack proper current_user_can() capability validation, the environment is vulnerable to unauthorized 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 WP Mailgun SMTP to the latest version once available, or implement proper WordPress capability checks (current_user_can) and nonce verification on all administrative functions. Review the plugin for other authorization gaps.
