AVideo affected by Session Hijacking via Unauthenticated Session ID Disclosure with Permissive CORS
### Summary
`/objects/phpsessionid.json.php` exposes the current PHP session ID to any unauthenticated request. The `allowOrigin()` function reflects any `Origin` header back in `Access-Control-Allow-Origin` with `Access-Control-Allow-Credentials: true`, enabling cross-origin session theft and full account takeover.
### Details
**File:** `objects/phpsessionid.json.php`
```php
allowOrigin();
$obj = new stdClass();
$obj->phpsessid = session_id();
echo _json_encode($obj);
```
No authentication is required. The `allowOrigin()` function in `objects/functions.php` (line ~2648) reflects the request Origin:
```php
$HTTP_ORIGIN = empty($_SERVER['HTTP_ORIGIN']) ? @$_SERVER['HTTP_REFERER'] : $_S
