- Backdrop Core 1.16.x versions prior to 1.16.4
- Backdrop Core 1.17.x versions prior to 1.17.1
Backdrop versions 1.15 and prior do not receive security coverage.
There will be a security release of Backdrop 1.17.x, and 1.16.x on Sept 30th, 2020 between 19:00 - 23:00 UTC. Security release announcements will appear here, on the Backdrop security page. This release will not require a database update.
Because Backdrop issued its regularly scheduled minor release on September 15th, and based on the severity of these issues, the Backdrop Security Team has agreed to postpone this security release for two weeks.
