## Description

AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains an open redirect in objects/playlistSort.php. Because the endpoint is not a *.json.php script, AVideo's automatic CSRF guard (autoCSRFGuard()/forbidIfIsUntrustedRequest()) does not run, and when the request includes the sort parameter the script issues a Location header set to the unvalidated $_SERVER['HTTP_REFERER'] value without calling isSafeRedirectURL(). A remote unauthenticated attacker can therefore induce a logged-in user who can manage the targeted playlist to submit a cross-origin POST with a crafted Referer, causing the victim's playlist to be reordered and the victim's browser to be redirected from a trusted AVideo URL to an attacker-controlled site for phishing. No patched version is available.
