The Node Quick Find module 6.x-1.1 for Drupal does not use db_rewrite_sql when presenting node titles, which allows remote attackers to bypass intended access restrictions and read potentially sensitive node titles via the autocomplete feature.
Semantically-Interconnected Online Communities (SIOC) 5.x before 5.x-1.2 and 6.x before 6.x-1.1, a module for Drupal, does not properly implement menu and database APIs, which allows remote attackers to obtain usernames and read hashed emails and comments via unspecified vectors.
The Forward module 6.x-1.x before 6.x-1.21 and 7.x-1.x before 7.x-1.3 for Drupal does not properly enforce permissions for (1) Recent forwards, (2) Most forwarded, or (3) Dynamic blocks, which allows remote attackers to obtain node titles via unspecified vectors.
The "have you forgotten your password" links in the User module in Drupal 7.x before 7.43 and 8.x before 8.0.4 allow remote attackers to obtain sensitive username information by leveraging a configuration that permits using an email address to login and a module that permits logging in.
