WWBN AVideo is an open source video platform. In versions 26.0 and prior, the EPG (Electronic Program Guide) link feature in AVideo allows authenticated users with upload permissions to store arbitrary URLs that the server fetches on every EPG page visit. The URL is validated only with PHP's FILTER_VALIDATE_URL, which accepts internal network addresses. Although AVideo has a dedicated isSSRFSafeURL() function for preventing SSRF, it is not called in this code path. This results in a stored server-side request forgery vulnerability that can be used to scan internal networks, access cloud metadata services, and interact with internal services. At time of publication, there are no publicly available patches.

GHSA-x5vx-vrpf-r45f — AVideo: Stored SSRF via Video EPG Link Missing isSSRFSafeURL() Validation

Affected: Packagist: wwbn/avideo

## Summary

The EPG (Electronic Program Guide) link feature in AVideo allows authenticated users with upload permissions to store arbitrary URLs that the server fetches on every EPG page visit. The URL is validated only with PHP's `FILTER_VALIDATE_URL`, which accepts internal network addresses. Although AVideo has a dedicated `isSSRFSafeURL()` function for preventing SSRF, it is not called in this code path. This results in a stored server-side request forgery vulnerability that can be used to scan internal networks, access cloud metadata services, and interact with internal services.

## Details

When a user adds or edits a video, the EPG link is stored via `objects/videoAddNew.json.php:119`:

```php $obj->setEpg_link($_POST['epg_link']); ```

The only validation applied is `FILTER_VALIDATE_URL`, which accepts URLs targeting internal addresses such as `http://127.0.0.1`, `http://169.254.169.254`, or `http://10.0.0.1`.

Later, when the EPG data is parsed, the stored URL is fetched server-side at `objects/EpgParser.php:358`:

```php $this->content = @\file_get_contents($this->url); ```

The `file_get_contents()` function follows redirects and supports multiple protocols including `http://`, `https://`, `ftp://`, and depending on PHP configuration, `php://` and other stream wrappers.

The codebase contains an `isSSRFSafeURL()` function that validates URLs against internal network ranges, but this function is not invoked anywhere in the EPG link processing path.
