plugins/event_tracer/event_list.php in PhpWebGallery 1.7.2 and earlier allows remote authenticated administrators to execute arbitrary PHP code via PHP sequences in the sort parameter, which is processed by create_function.

PhpWebGallery 1.7.0 and 1.7.1 allows remote authenticated users with advisor privileges to obtain the real e-mail addresses of other users by editing the user's profile.

Multiple SQL injection vulnerabilities in PhpWebGallery 1.5.1 and earlier allow remote attackers to execute arbitrary SQL commands via the (1) since, (2) sort_by, and (3) items_number parameters to comments.php, (4) the search parameter to category.php, and (5) image_id parameter to picture.php. NOTE: it was later reported that the comments.php/sort_by vector also affects 1.7.2 and earlier.
