Security risk: 
Moderately Critical
  • Third Party Libraries
  • To Be Announced

The Backdrop Security Team will be coordinating a security release for Backdrop 1.19 and 1.18 this week on Thursday, August 12, 2021

We are issuing this PSA in advance because August 12, 2021 is not a security window in the regular Drupal security release window schedule, and since we coordinate security releases with Drupal, there would not normally be any security release on this date.

The Backdrop core release will be made between 16:00 – 22:00 UTC (noon – 6:00pm EDT). It is rated as moderately critical and will be an update to a vendor library only.
