Open redirect vulnerability in the Overlay module in Drupal 7.x before 7.41, the jQuery Update module 7.x-2.x before 7.x-2.7 for Drupal, and the LABjs module 7.x-1.x before 7.x-1.8 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-3233.

The Entity Registration module 7.x-1.x before 7.x-1.5 for Drupal allows remote attackers to obtain sensitive event registration information by leveraging the "Register other accounts" permission and knowledge of usernames.

The escapeLike function in sqlsrv/database.inc in the Drupal 7 driver for SQL Server and SQL Azure 7.x-1.x before 7.x-1.4 does not properly escape certain characters, which allows remote attackers to execute arbitrary SQL commands via vectors involving a module using the db_like function.

Cross-site scripting (XSS) vulnerability in the Ajax handler in Drupal 7.x before 7.39 and the Ctools module 6.x-1.x before 6.x-1.14 for Drupal allows remote attackers to inject arbitrary web script or HTML via vectors involving a whitelisted HTML element, possibly related to the "a" tag.

Cross-site request forgery (CSRF) vulnerability in Drupal 7.12 and earlier allows remote attackers to hijack the authentication of arbitrary users for requests that end a session via the user/logout URI. NOTE: the vendor disputes the significance of this issue, by considering the "security benefit against platform complexity and performance impact" and concluding that a change to the logout behavior is not planned because "for most sites it is not worth the trade-off.
