Consul

2.0.0 (May 22, 2026)

SECURITY:

• connect: Upgrade envoy version to 1.37.2 and newer versions [GH-23469]
• go: Upgrade go version to 1.26 [GH-23493]
• agent: Increased default HTTP server timeouts to prevent breaking long-polling blocking queries. read_timeout and write_timeout are now set to 15 minutes (up from 30 seconds), while read_header_timeout (10s) and idle_timeout (120s) still provide protection against Slowloris attacks. All timeouts remain configurable via the http_config block. [GH-23267]
• api-gateway, terminating-gateway: Apply HTTP request path normalization on api-gateway and terminating-gateway HTTP listeners to prevent L7 intention RBAC bypass via non-normalized paths (CVE-2024-10005). [GH-23534]
• docker: update ubi base image to ubi9-minimal:9.7. [GH-23553]
• docker: Upgrade curl to >= 8.20.0 from Alpine edge in the container image to address CVE-2026-6429, CVE-2026-4873, CVE-2026-5773, CVE-2026-6253, CVE-2026-6276, CVE-2026-7168, CVE-2026-5545. Alpine 3.23 stable does not yet carry the patched version. [GH-23750]
• docker: Update to UBI base image to 9.8 for fixing [CVE_2026-2100] [GH-23588]

FEATURES:

• (Enterprise Only) update to go-licensing/v4 and go-census/v3 inorder to adapt to new licenses of PAO.
• Global Rate Limiter: (Enterprise Only) a new "rate-limit" config entry kind that enables dynamic, cluster-wide RPC rate limiting stored in Raft and automatically replicated to all servers. This allows operators to apply or adjust global rate limits at runtime without restarting Consul servers — a critical capability for emergency scenarios where the cluster is under excessive load.
• api-gateway: Added SDS certificate support for API Gateway listeners, including listener-level default TLS certificates and HTTP/TCP route service TLS SDS overrides. Service overrides inherit the listener SDS cluster when omitted, and gateway validation/xDS generation now rejects conflicting override mappings to keep certificate selection deterministic. [GH-23354]
• api-gateway: add support for gateway-level default upstream limits and route service-level limit overrides for MaxConnections, MaxPendingRequests, and MaxConcurrentRequests. [GH-23396]
• api: Added new API "/v1/internal/rpc/methods" that lists all RPC method names. Requires an operator:read ACL token. This is useful when users want to configure rate limits that exclude specific RPC endpoints. [GH-23329]
• ca: (Enterprise Only) Added new Connect CA provider for Cyberark WIM (connect.ca_provider = "pan-distributed-issuer"), enabling Consul to issue certificates through Cyberark WIM.
• server: (Enterprise Only) add stable cluster identity and leader-gated global registry sync for service summary publishing.
• telemetry: (Enterprise Only) Product telemetry for self-managed Consul with anonymous, opt-in usage reporting.
• mesh: (Enterprise Only) Introduce support for multi-port (named port) services in Consul, including the ability to specify and route traffic using port names, as well as to retrieve virtual IPs for specific service ports. It also enforces that certain advanced multi-port features are only available in Consul Enterprise, and includes new utility functions for cluster naming and ALPN protocol generation.

IMPROVEMENTS:

• agent: (Enterprise Only) Add eventually-consistent background cache for Enterprise usage metrics, reducing GET /v1/operator/usage latency from O(PNK) to O(1) and lowering CPU/memory pressure during high-frequency scraping via a watch-driven maintainer goroutine.
• mesh: (Enterprise Only) Introduce support for multi-port (named port) services in Consul, including the ability to specify and route traffic using port names, as well as to retrieve virtual IPs for specific service ports. It also enforces that certain advanced multi-port features are only available in Consul Enterprise, and includes new utility functions for cluster naming and ALPN protocol generation.
• terminating-gateway: Updated the cluster upstream tls to use sds instead of static certs, allowing for dynamic certificate updates without needing to restart the terminating gateway. [GH-23288]
• telemetry: Add certificate expiry monitoring with Prometheus metrics (labeled with datacenter/partition/namespace), structured logging with configurable severity thresholds, and enhanced Connect CA API to include NotAfter field for root and intermediate certificates. [GH-23147]
• deps: Upgrade github.com/hashicorp/vault/sdk from v0.7.0 to v0.25.1 and github.com/hashicorp/vault/api from v1.12.2 to v1.16.0. [GH-23574]
• test-integ: upgrade testcontainers-go (v0.22.0->v0.40.0) and docker/docker (v24.0.5->v28.5.1) in the integration test module. This removes opencontainers/runc as a Go dependency of the test framework. These are test infrastructure dependencies only and have no impact on the consul binary or any consul deployment. [GH-23573]
• xds: (Enterprise Only) add Consecutive5xx, ConsecutiveGatewayFailure, and EnforcingConsecutiveGatewayFailure fields to PassiveHealthCheck, allowing operators to configure Envoy outlier detection thresholds for 5xx responses and gateway failures (502/503/504) on upstreams defaults.

BUG FIXES:

• audit-logging: (Enterprise Only) Fixed JSON unmarshall error when array of obj is passed for auditReq body.
• cli: Enhanced error messages in consul config write command to provide actionable guidance when config entries cannot be modified due to references by gateways or routers. [GH-22921]
• xds: Fixed XDS package to generate correct endpoints and cluster configurations for API Gateways when peered, and updated the API Gateway update handler to propogate mesh gateway config to its upstreams. [GH-23454]
• XDS: Fixes issue with mesh-gateway in remote mode on AWS EKS, as DNS hostnames are assigned to AWS NLBs instead of IPs and envoy's EDS endpoint validation expects address to be an IP. Now EDS load assignment is skipped for non-peer remote mesh gateway targets with hostname based gateways keeping CDS/EDS in sync. [GH-23543]
• api-gateway: resolve service subsets for routes during API gateway discovery chain synthesis. [GH-23294]
• ui: Fix broken documentation links [GH-23578]

1.19.0 (June 12, 2024)

This release is created to share the Consul Enterprise changelog and notify consumers of availability. The attached source and assets do not include Consul Enterprise code and should not be used in place of official Docker images or binaries.

BREAKING CHANGES:

• telemetry: State store usage metrics with a double consul element in the metric name have been removed. Please use the same metric without the second consul instead. As an example instead of consul.consul.state.config_entries use consul.state.config_entries [GH-20674]

SECURITY:

• Upgrade to support Envoy 1.27.5 and 1.28.3. This resolves CVE CVE-2024-32475 (auto_sni). [GH-21017]
• Upgrade to support k8s.io/apimachinery v0.18.7 or higher. This resolves CVE CVE-2020-8559. [GH-21017]

FEATURES:

• dns: queries now default to a refactored DNS server that is v1 and v2 Catalog compatible. Use v1dns in the experiments agent config to disable. The legacy server will be removed in a future release of Consul. See the Consul 1.19.x Release Notes for removed DNS features. [GH-20715]
• gateways: api-gateway can leverage listener TLS certificates available on the gateway's local filesystem by specifying the public certificate and private key path in the new file-system-certificate configuration entry [GH-20873]

IMPROVEMENTS:

• dns: new version was not supporting partition or namespace being set to 'default' in CE version. [GH-21230]
• mesh: update supported envoy version 1.29.4 in addition to 1.28.3, 1.27.5, 1.26.8. [GH-21142]
• upgrade go version to v1.22.4. [GH-21265]
• Upgrade github.com/envoyproxy/go-control-plane to 0.12.0. [GH-20973]
• dns: DNS-over-grpc when using consul-dataplane now accepts partition, namespace, token as metadata to default those query parameters. consul-dataplane v1.5+ will send this information automatically. [GH-20899]
• snapshot: Add consul snapshot decode CLI command to output a JSON object stream of all the snapshots data. [GH-20824]
• telemetry: Add telemetry.disable_per_tenancy_usage_metrics in agent configuration to disable setting tenancy labels on usage metrics. This significantly decreases CPU utilization in clusters with many admin partitions or namespaces.
• telemetry: Improved the performance usage metrics emission by not outputting redundant metrics. [GH-20674]

DEPRECATIONS:

• snapshot agent: (Enterprise only) Top level single snapshot destinations local_storage, aws_storage, azure_blob_storage, and google_storage in snapshot agent configuration files are now deprecated. Use the backup_destinations config object instead.

BUG FIXES:

• docs: Consul DNS Forwarding configuration for OpenShift update for Resolve Consul DNS Requests in Kubernetes [GH-20439]
• hcp: fix error logs when failing to push metrics [GH-20514]
• streaming: Handle ACL errors consistently when blocking query timeout is reached. [GH-20876]
