Encrypt your secrets with HashiCorp Vault

We're ramping up our encryption options again in Bitbucket 8.16, giving you more autonomy for securely storing your secrets. In Bitbucket 8.15, we offered AWS Secrets Manager as a new encryption option for storing passwords and credentials. When you upgrade to Bitbucket 8.16, you can now store your secrets in HashiCorp Vault. When using V2 of the HashiCorp KV Secret Engine, choose from two encryption options — HashiCorp tokens and Kubernetes Service Account Tokens.

Bitbucket 8.16.3 security enhancement: App upload through UPM and REST API disabled by default

In Bitbucket Data Center 8.18.0, two ways of app installation through UPM (the Universal Plugin Manager) became disabled by default:

  • with the Upload app button on the Manage apps page
  • with the REST API

We've also backported this change to Bitbucket 8.16.3. So in Bitbucket 8.16.3 and all the next bugfix releases of Bitbucket 8.16.x, you can install new apps only by selecting the Install button on the Find new apps page. This limitation prevents unwanted uploads of potentially malicious files to your Bitbucket instance. 

If you need to enable app installation with the Upload app button on the Manage apps page or with the REST API, set the following property in the file:


If app installation from files and through the REST API is an integral part of your workflow, we strongly recommend setting the relevant property to enable it prior to the upgrade.

If you decide to enable the feature after the upgrade, make sure to restart your instance for the changes to take effect.

If you run a Bitbucket cluster, a rolling restart is enough to pick up the configuration properties you set to enable the features.

Before you upgrade to 8.16

Bitbucket Data Center now includes Java 17

Bitbucket 8.16 and later will run on Java 17 if you use the installer. Learn how to run the Bitbucket installer

H2 database migration requirement

The H2 database driver has been upgraded to the currently latest version 2.2.220. The upgrade has boosted data security.

For upgrades to Bitbucket 8.8 and later or Mesh 1.5 and later, manual data migration is required if any of the following applies:

  • you’re using a mirror

  • you’re using Bitbucket Server with a H2 database

  • you’ve set up Bitbucket Mesh
