CVE-2024-3235
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 · uneditedThe Essential Grid Gallery WordPress Plugin plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 3.1.1 via the on_front_ajax_action() function. This makes it possible for unauthenticated attackers to view private and password protected posts that may have private or sensitive information.
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 · high confidenceThe Essential Grid Gallery WordPress plugin up to version 3.1.1 has an information disclosure vulnerability in its on_front_ajax_action() function. The AJAX handler fails to properly enforce access controls, allowing unauthenticated attackers to query and retrieve private and password-protected posts through the WordPress AJAX interface, exposing sensitive content that should require authentication to access.

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 Essential Grid Gallery plugin is installedIn WordPress admin, go to Plugins > Installed Plugins and look for 'Essential Grid Gallery' or check the plugins directory for the essential-grid folderAffected if The plugin is not installed or has been removed, then the vulnerability does not apply
-
Determine installed plugin versionIn WordPress admin > Plugins > Installed Plugins, find Essential Grid Gallery and note the version number displayedAffected if Version is 3.1.1 or lower (any version up to and including 3.1.1 is affected)
-
Confirm the on_front_ajax_action AJAX endpoint existsCheck if the file essential-grid/essential-grid.php or similar contains the function on_front_ajax_action, or test for the presence of the AJAX handler by reviewing plugin source files for the wp_ajax_nopriv hook on this functionAffected if The AJAX handler function exists and is hooked to WordPress AJAX without proper capability checks
-
Test unauthenticated access to protected contentSend a crafted AJAX request to the WordPress AJAX endpoint (typically /wp-admin/admin-ajax.php) with an action parameter that triggers on_front_ajax_action, attempting to query private or password-protected posts without providing authentication credentialsAffected if The request returns private or password-protected post content without requiring authentication, confirming the access control failure
If Essential Grid Gallery version 3.1.1 or lower is installed and the on_front_ajax_action AJAX endpoint is accessible to unauthenticated users, the environment is affected by this information disclosure vulnerability.

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 Essential Grid Gallery to version 3.1.2 or later which contains the access control fix. If immediate updating is not feasible, consider restricting access to the vulnerable AJAX endpoint or temporarily disabling the plugin.
