    Enforce allowed URLs for SASL OAUTHBEARER authentication

    Aiven for Apache Kafka now enforces an allowed list of URLs for SASL OAUTHBEARER authentication to address CVE-2025-27817.

    By default, the value from sasl_oauthbearer_jwks_endpoint_url is added automatically to the allowed list. You can explicitly allow additional URLs by setting sasl_oauthbearer_allowed_urls.

    URLs that are not included in either sasl_oauthbearer_allowed_urls or sasl_oauthbearer_jwks_endpoint_url are now blocked for SASL OAUTHBEARER authentication.

    Although Apache Kafka Connect and Apache Kafka MirrorMaker 2 do not officially support SASL OAUTHBEARER, this change prevents unsupported configurations from bypassing security controls.

    • Aiven Terraform provider

    Aiven Provider for Terraform version 4.48.0 now available

    This version of the Aiven Terraform Provider adds write-only password support to service user resources, including aiven_kafka_user, aiven_mysql_user, aiven_opensearch_user, aiven_pg_user, and aiven_valkey_user. You can now manage passwords for these service users securely without storing them in your state file by using the new password_wo and password_wo_version fields.

    Additionally, a new aiven_organization_user_group_member_list data source has been added. It lists all members of a specific user group, making group and permission management easier.

    This release also includes regular updates to service configurations, integrations, and endpoints. For more details on fixes and updates, view the complete Aiven Provider for Terraform changelog.

    Aiven for Valkey™ clustering: out now in limited availability

    We are excited to announce the launch of Aiven for Valkey™ clustering in limited availability. This managed solution provides scalable, distributed in-memory data storage with built-in high availability.

    Aiven for Valkey clustering automatically partitions your data across multiple nodes (shards), enabling you to handle larger datasets and higher traffic loads than a single-node deployment.

    Key benefits:

    • High availability: Automatic failover, minimal downtime, and replica promotion to maintain service continuity during unexpected failures or maintenance.
    • Scalability & performance: Distribute read and write operations across multiple shards for significantly higher throughput, lower latency, and better load distribution.
    • Compatibility: Fully compatible with existing Valkey cluster-aware client libraries for seamless integration with current applications.
    • Flexible sizing: Supports various instance sizes, including smaller 4 GB RAM instances, allowing for better cost optimization.

    Learn more in the Aiven for Valkey™ clustering documentation.

    Aiven for PostgreSQL® reads failover to primary

    Aiven for PostgreSQL® now supports automatic failover for read-only workloads. When all standby nodes are unavailable, read traffic routed to the HA replica DNS endpoint is automatically redirected to the healthy primary node, ensuring uninterrupted access and minimizing downtime.

    Key highlights:

    • Seamless failover for read-only queries when standbys are unavailable
    • No application-side routing changes required
    • Single, stable connection endpoint for read traffic
    • Easy enable/disable via Console, CLI, API, Terraform, or Kubernetes

    This is a limited availability feature. To learn more, see the feature documentation.

    Support public CA for SASL authentication in Aiven for Apache Kafka

    You can now configure Aiven for Apache Kafka to use a public certificate authority (Let’s Encrypt) for SASL authentication instead of a project-specific CA. This eliminates the need for clients to install and manage certificates when authenticating with username and password.

    When you enable this option, the connection details display the appropriate SASL port for your access route. Public CA support is available for all connection types, including PrivateLink.

    To enable Public CA, use the Aiven Console, Aiven CLI, API, or Terraform. For more information, see Enable public CA for SASL authentication.

    Karapace version 5.0.3

    Karapace has been updated to version 5.0.3 with fixes that improve protobuf handling and message consumption.

    Improved

    • Protobuf schemas now use absolute runtime paths when compiled, ensuring that generated *_pb2.py modules load correctly across different runtime environments.

    Fixed

    • Fixed protobuf decoding failures that caused messages to appear empty or not load in the Kafka Topic Catalog and REST API.
    • Fixed an error where protobuf keys that could not be decoded resulted in an Unprocessable Entity response. Karapace now falls back to binary decoding for the key.
    • Fixed errors that caused protobuf-formatted messages to fail when fetched through the API or the Aiven Console.

    For more information, see the Karapace 5.0.3 release notes.
