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.

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 confidenceA Missing Authorization vulnerability in the OceanWP Ocean Extra WordPress plugin allows attackers to access functionality that should require proper authentication and authorization. The plugin fails to properly enforce access control checks on certain endpoints or functions, allowing exploitation of incorrectly configured security levels.

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 Ocean Extra plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Ocean Extra' or check the /wp-content/plugins/ocean-extra/ directory via file systemAffected if Ocean Extra plugin is active on the WordPress site
-
Determine installed version of Ocean ExtraCheck the plugin header in ocean-extra/ocean-extra.php for 'Version:' line, or view the plugin in WordPress admin plugins listAffected if Version is older than the fixed release containing proper authorization checks
-
Identify publicly accessible admin functionsReview the plugin files in ocean-extra/includes/ directory for functions that perform admin-level operations (database changes, user management, settings modifications) without capability checks like 'manage_options' or nonce verificationAffected if Functions performing sensitive operations lack current_user_can() capability checks or wp_verify_nonce() verification
-
Test for unauthorized endpoint accessMake HTTP requests to common Ocean Extra AJAX endpoints (admin-ajax.php?action=ocean_* and rest/ocean/* routes) without providing authentication cookies or Authorization headersAffected if Endpoints respond successfully to unauthenticated requests and return data or perform actions that should require admin privileges
-
Check for missing nonce verification in AJAX handlersInspect PHP files containing add_action('wp_ajax_*') calls for missing wp_verify_nonce() or check_admin_referer() calls before processing requestsAffected if AJAX action handlers execute without validating nonce tokens
The site is affected if Ocean Extra plugin is active and its endpoints or functions can be accessed or executed without proper authentication or authorization capability checks.

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 Ocean Extra plugin to the latest version which should contain proper authorization checks. If no update is available, audit the plugin code for functions lacking capability checks or nonce verification and add appropriate authorization controls.
