WWBN AVideo is an open source video platform. In versions up to and including 26.0, the Gallery plugin's `saveSort.json.php` endpoint passes unsanitized user input from `$_REQUEST['sections']` array values directly into PHP's `eval()` function. While the endpoint is gated behind `User::isAdmin()`, it has no CSRF token validation. Combined with AVideo's explicit `SameSite=None` session cookie configuration, an attacker can exploit this via cross-site request forgery to achieve unauthenticated remote code execution — requiring only that an admin visits an attacker-controlled page. Commit 087dab8841f8bdb54be184105ef19b47c5698fcb contains a patch.

GHSA-xggw-g9pm-9qhh — AVideo has PHP Code Injection via eval() in Gallery saveSort.json.php Exploitable Through CSRF Against Admin

Affected: Packagist: wwbn/avideo

## Summary

The Gallery plugin's `saveSort.json.php` endpoint passes unsanitized user input from `$_REQUEST['sections']` array values directly into PHP's `eval()` function. While the endpoint is gated behind `User::isAdmin()`, it has no CSRF token validation. Combined with AVideo's explicit `SameSite=None` session cookie configuration, an attacker can exploit this via cross-site request forgery to achieve unauthenticated remote code execution — requiring only that an admin visits an attacker-controlled page.

## Details

**Vulnerable code** — `plugin/Gallery/view/saveSort.json.php:20-25`:

```php if(!empty($_REQUEST['sections'])){ $object = $gallery->getDataObject(); foreach ($_REQUEST['sections'] as $key => $value) { $obj->sectionsSaved[] = array($key=>$value); eval("\$object->{$value}Order = \$key;"); } $obj->error = !$gallery->setDataObject($object); } ```

The `$value` variable from `$_REQUEST['sections']` is interpolated directly into the string passed to `eval()` with no sanitization — no allowlist, no regex validation, no escaping. Normal Gallery usage sends section names like `'Shorts'`, `'Trending'`, etc. from jQuery UI sortable, but the server enforces no such constraint.

**CSRF enablement** — `objects/include_config.php:134-137`:

```php if ($isHTTPS) { ini_set('session.cookie_samesite', 'None'); ini_set('session.cookie_secure', '1'); } ```

The session cookie is explicitly set to `SameSite=None`, which instructs browsers t…
