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.

The Relevant Content module 5.x before 5.x-1.4 and 6.x before 6.x-1.5 for Drupal does not properly implement node access logic, which allows remote attackers to discover restricted node titles and relationships.
