Views - Critical - Access Bypass - SA-CONTRIB-2015-103

The Views module provides a flexible method for Drupal site designers to control how lists and tables of content, users, taxonomy terms and other data are presented.

Access bypass due cache inconsistency

Due to an issue in the caching mechanism of Views it’s possible that configured filters lose their effect.
This can lead to exposure of content that otherwise would be hidden from visitors.
This vulnerability is mitigated by the fact that it can’t be exploited directly but occurs when certain prerequisites meet.
Systems that use in-memory cache backends like redis / memcache are more likely to be affected by this issue. This is due the common strategy used to free cache space if the configured memory limit of the cache is reached.
