It has been accustomed that a Drupal security update is released today which tends to be remarkably imperative. It is also co-related with the Drupalgeddon dilemma that happened in 2014, but on the contrary, it won’t be going to affect Drupal core. The released updation consists of few contributing modules so it will not be going to modify your site in any way, then also checking the updates is strongly recommended. It is estimated that the updation will be released by today at 5pm. In any cases if your site is affected, you can apply patches without delay else exploits are likely to be developed with some hours or days.
