Release Notes for This Release



PrivX 32.3 is an incremental release with security and bug fixes.



32.2 is an incremental release to address the Terrapin vulnerability. The fix includes the following changes:

PrivX SSH Proxy and SSH Bastion enable the OpenSSH strict KEX protocol extension when the target server and client express support for it during the initial KEX exchange. algorithm is removed from the sets of default sshtarget and sshclient ciphers. and algorithms are removed from the sets of default sshtarget and sshclient macs. It is possible to revert to using the vulnerable algorithm combinations by editing the /opt/privx/etc/ssh-algorithms.toml file. This is not recommended unless you are certain that all target servers and clients, that PrivX communicates with, support the OpenSSH strict KEX protocol extension.



This minor release fixes Carrier browser images(chromium, chromium_lite). Upgrade involves downloading new browser images and tagging them to match the current PrivX Carrier version.

This example shows how to upgrade the Chromium container image on PrivX Carrier 32.1

# docker pull
# docker tag



32.1 is an incremental release that fixes some performance and stability issues found in 32.0.

Important Notes for This Release

Update to API Roles Parameters

The Role-Store API has been updated for managing user roles in the /role-store/api/v1/users/{user_id}/roles endpoint, affecting both GET and PUT requests. The method for defining validity periods for time-limited roles has changed. Previously, these periods were set using grant_start and grant_end attributes in the root object. Now, they are specified within the grant_validity_periods array, which supports multiple time ranges.

See API specification

Monitor-service instance status endpoint at /monitor-service/api/v1/instance/status used for load balancer status checks is no longer returning JSON body for unauthenticated requests. Status codes (200 for OK, 500 for instance down) still remain the same and should be used for LB health checks.

PostgreSQL 9.x and 10.x Support Ended

PostgreSQL 9.x and 10.x have reached end of life since 2021 and 2022 respectively and official support for these database is ended from this release. To upgrade the PrivX database, see Upgrade PrivX Database to Supported Version.

Preserve Custom Browsers when Updating Carrier Configuration

If you use a custom-browser image, and upgrade Carriers and their configurations, ensure that your custom-browser image is specified in the Carrier configuration carrier-config.toml. The name of the custom-browser image must be specified in the default setting under the [web_browsers] section.

Rocky Linux/RHEL 9 official support added and CentOS/RHEL 7 support Ending

CentOS 7 and RHEL 7 will reach end of life on June 30, 2024. PrivX aims to end installation support for these platforms on the same timeline. Starting from PrivX 32, Rocky Linux 9 and RHEL 9 are officially supported. See Migrate from EOL Operating Systems.

Deprecation Warnings

Redis Support Ending
Redis support will be ended in a future release. We recommend you change to PostgreSQL for PrivX microservice notifications. Please change notification mechanism to PostgreSQL if your PrivX still uses Redis for notifications.

SHA-1-Certificate End of Support Imminent
Support for certificates signed with SHA-1 shall be dropped in future PrivX releases.

By default PrivX will not trust certificates with SHA-1 signatures unless they are self-signed. Re-enabling trust for such certificates requires setting the GODEBUG=x509sha1=1 environment variable for PrivX microservices and tools.

Practical attacks against SHA-1 have been demonstrated in 2017 and publicly trusted Certificate Authorities have not issued SHA-1 certificates since 2015.

privx-cmd and PrivX-Agent support for old platforms ending

privx-cmd and agents released in PrivX v33 and later may not support old platforms:

  • Windows 7, 8, Server 2008 and Server 2012.
  • MacOS versions 10.14 and older.

If you use agents or privx-cmd for enabling native-client connections, ensure that the users' OS is updated.

Supported releases and upgrade path

After this release, we provide security and stability fixes for PrivX 32.x, 31.x, and 30.x. Older versions are not officially supported. We recommend you upgrade as soon as you can if you are running an unsupported version.

Upgrading to this version is supported from three previous major versions (31.x, 30.x, 29.x). For more information about upgrading from older versions, see Upgrade from Older Releases.
