Release Announcement

SecureDrop 2.2.0 Released

February 17, 2022

We’re pleased to announce that SecureDrop 2.2.0 has been released. Changes that journalists and administrators should be aware of are summarized in this blog post. A complete list of changes can be found on GitHub.

What’s new in SecureDrop 2.2.0?

For all users

  • Localization: Timestamps will now be displayed using the language’s “long” format (Issue, Pull Request).
  • Security: The security-related defensive HTTP headers that prevent various types of attacks on the Source and Journalist Interfaces have been improved (Issue, Pull Request).

For sources

  • Usability: The “Refresh codename” feature has been removed to avoid potential user confusion (Pull Request). A bug with the display of the “Forgot your codename?” hint has been fixed (Issue, Pull Request).

For journalists

  • Accessibility: The Journalist Interface now uses more standards-compliant semantic HTML and ARIA annotations to improve accessibility (Issue, Pull Request).

For administrators

  • Hardware support: The grsecurity-patched Linux Kernel has been upgraded from 5.4.136 to 5.15.18, adding support for newer hardware (Issue, Pull Request).
  • Hardware deprecation: SecureDrop 2.2.x will be the last release series to support Mac Minis and Intel 5th-gen NUCs. If you are still using these, you must move to a supported hardware platform as soon as possible (Pull Request).
  • Security: Newly set HOTP (Yubikey) two-factor secrets, either when creating a new journalist account or changing an existing one, are now 160 bits (40 hex characters) in length (Issue, Pull Request).
  • Security: Journalist accounts have always been expected to have two-factor secrets that are at least 80 bits in length. Accounts with shorter, invalid secrets will now be unable to log in, an administrator will need to reset the account’s two-factor credentials in this case. This applies to both 2FA apps like FreeOTP and Google Authenticator (TOTP) and Yubikeys (HOTP) (Pull Request).
  • User account management: When deleting a journalist’s account, some information associated with their account like past replies and whether a message has been seen will now be associated with an internal “deleted” account (Issue, Pull Request).
  • Dependency updates: The following dependencies have been updated (Pull Requests: 1, 2):
    • click from 6.7 to 8.0.3
    • flask-babel from 011.2 to 2.0.0
    • flask-wtf from 0.14.2 to 1.0.0
    • Flask from 1.0.2 to 2.0.2
    • itsdangerous from 0.24 to 2.0.1
    • jinja2 from 2.11.3 to 3.0.2
    • markupsafe from 1.1.1 to 2.0.1
    • redis from 3.3.6 to 3.5.3
    • rq from 1.1.0 to 1.10.0
    • werkzeug from 0.16.0 to 2.0.2
    • wtforms from 2.1.0 to 3.0.0

What administrators need to do

SecureDrop Application and Monitor Servers will be updated to SecureDrop 2.2.0 automatically within 24 hours of the release. As with previous releases, we recommend that you update your Tails workstations to the latest version of Tails and the latest version of SecureDrop. Please see our upgrade guide for instructions.

SecureDrop 2.2.x is the last release series to include official support for Apple Mac Minis and Intel NUC5 hardware. Newer NUC models will continue to be supported. If you are using Mac Minis or Intel NUC5s, we urge you to migrate to to supported hardware at your earliest convenience.
