SQL injection vulnerability in Piwigo before 2.5.6, 2.6.x before 2.6.5, and 2.7.x before 2.7.3 allows remote attackers to execute arbitrary SQL commands via unspecified vectors.

SQL injection vulnerability in the rate_picture function in include/functions_rate.inc.php in Piwigo before 2.5.5, 2.6.x before 2.6.4, and 2.7.x before 2.7.2 allows remote attackers to execute arbitrary SQL commands via the rate parameter to picture.php, related to an improper data type in a comparison of a non-numeric value that begins with a digit.

Cross-site scripting (XSS) vulnerability in admin/picture_modify.php in the photo-edit subsystem in Piwigo 2.6.3 and earlier allows remote attackers to inject arbitrary web script or HTML via the associate[] field, a different vulnerability than CVE-2014-4649.
