Multiple cross-site scripting (XSS) vulnerabilities in modules_v3/googlemap/wt_v3_street_view.php in webtrees before 1.5.2 allow remote attackers to inject arbitrary web script or HTML via the (1) map, (2) streetview, or (3) reset parameter.

Webtrees 2.1.18 is vulnerable to Directory Traversal. By manipulating the "media_folder" parameter in the URL, an attacker (in this case, an administrator) can navigate beyond the intended directory (the 'media/' directory) to access sensitive files in other parts of the application's file system.
