Description Adam Mariš 2016-05-24 08:46:18 UTC

Cross-site scripting vulnerability in wp-includes/wp-db.php in WordPress before 4.2.2 allows remote attackers to inject arbitrary web script or HTML via a long comment that is improperly stored because of limitations on the MySQL TEXT data type.

This vulnerability was incompletely fixed in original patch for CVE-2015-3440.
