Cloudflare Release Notes

Cloudflare Advanced Network Firewall Country rules are now supported for accounts using Unified Routing mode. This feature requires a Cloudflare Advanced Network Firewall subscription.

You can create firewall rules that match traffic based on source or destination country to enforce geographic access policies across your network.

This is the first of the Cloudflare Advanced Network Firewall features to become available in Unified Routing. Support for additional features - IP Lists, ASN Lists, Threat Intel Lists, IDS, Rate Limiting, SIP, and Managed Rulesets - is planned.

For the full list of current beta limitations, refer to Traffic steering beta limitations.

Workflows now provides additional context inside step.do() callbacks and supports returning ReadableStream to handle larger step outputs.

Step context properties

The step.do() callback receives a context object with new properties alongside attempt:

• step.name — The name passed to step.do()
• step.count — How many times a step with that name has been invoked in this instance (1-indexed)
  • Useful when running the same step in a loop.
• config — The resolved step configuration, including timeout and retries with defaults applied

type ResolvedStepConfig = {
	retries: {
		limit: number;
		delay: WorkflowDelayDuration | number;
		backoff?: "constant" | "linear" | "exponential";
	};
	timeout: WorkflowTimeoutDuration | number;
};

type WorkflowStepContext = {
	step: {
		name: string;
		count: number;
	};
	attempt: number;
	config: ResolvedStepConfig;
};

ReadableStream support in step.do()

Steps can now return a ReadableStream directly. Although non-stream step outputs are limited to 1 MiB, streamed outputs support much larger payloads.

const largePayload = await step.do("fetch-large-file", async () => { …

The Container logs page now displays related Worker and Durable Object logs alongside container logs. This co-locates all relevant log events for a container application in one place, making it easier to trace requests and debug issues.

You can filter to a single source when you need to isolate Container, Worker, or Durable Object output.

For information on configuring container logging, refer to How do Container logs work?.

Pay-as-you-go customers can now monitor usage-based costs and configure spend alerts through two new features: the Billable Usage dashboard and Budget alerts.

Billable Usage dashboard

The Billable Usage dashboard provides daily visibility into usage-based costs across your Cloudflare account. The data comes from the same system that generates your monthly invoice, so the figures match your bill.

The dashboard displays:

• A bar chart showing daily usage charges for your billing period
• A sortable table breaking down usage by product, including total usage, billable usage, and cumulative costs
• Ability to view previous billing periods

Usage data aligns to your billing cycle, not the calendar month. The total usage cost shown at the end of a completed billing period matches the usage overage charges on your corresponding invoice.

To access the dashboard, go to Manage Account > Billing > Billable Usage.

Budget alerts

Budget alerts allow you to set dollar-based thresholds for your account-level usage spend. You receive an email notification when your projected monthly spend reaches your configured threshold, giving you proactive visibility into your bill before month-end. …

Binary frames received on a WebSocket are now delivered to the message event as Blob ↗︎ objects by default. This matches the WebSocket specification ↗︎ and standard browser behavior. Previously, binary frames were always delivered as ArrayBuffer ↗︎. The binaryType property on WebSocket controls the delivery type on a per-WebSocket basis.

This change has been active for Workers with compatibility dates on or after 2026-03-17, via the websocket_standard_binary_type compatibility flag. We should have documented this change when it shipped but didn't. We're sorry for the trouble that caused. If your Worker handles binary WebSocket messages and assumes event.data is an ArrayBuffer, the frames will arrive as Blob instead, and a naive instanceof ArrayBuffer check will silently drop every frame.

To opt back into ArrayBuffer delivery, assign binaryType before calling accept(). This works regardless of the compatibility flag:

const resp = await fetch("https://example.com", {
	headers: { Upgrade: "websocket" },
});
const ws = resp.webSocket; …

This week's release introduces a new detection for a Remote Code Execution (RCE) vulnerability in Apache ActiveMQ (CVE-2026-34197) and an updated signature for Magento 2 - Unrestricted File Upload. Alongside these detections, we are continuing our work on rule refinements to provide deeper security insights for our customers.

Key Findings

• Apache ActiveMQ (CVE-2026-34197): A vulnerability in Apache ActiveMQ allows an unauthenticated, remote attacker to execute arbitrary code. This flaw occurs during the processing of specially crafted network packets, leading to potential full system compromise.

• Magento 2 - Unrestricted File Upload - 2: This is a follow-up enhancement to our existing protections for Magento and Adobe Commerce.

Impact

Successful exploitation of these vulnerabilities could allow unauthenticated attackers to execute arbitrary code or gain full administrative control over affected servers. We strongly recommend applying official vendor patches for Apache ActiveMQ and Magento to address the underlying vulnerabilities.

Continuous Rule Improvements

We are continuously refining our managed rules to provide more resilient protection and deeper insights into attack patterns. To ensure an optimal security posture, we recommend consistently monitoring the Security Events dashboard and adjusting rule actions as these enhancements are deployed.

When a Cloudflare Worker intercepts a visitor request, it can dispatch additional outbound fetch calls called subrequests. By default, each subrequest generates its own log entry in Logpush, resulting in multiple log lines per visitor request. With subrequest merging enabled, subrequest data is embedded as a nested array field on the parent log record instead.

What's new

• New subrequest_merging field on Logpush jobs — Set "merge_subrequests": true when creating or updating an http_requests Logpush job to enable the feature.
• New Subrequests log field — When subrequest merging is enabled, a Subrequests field (array\<object\>) is added to each parent request log record. Each element in the array contains the standard http_requests fields for that subrequest.

Limitations

• Applies to the http_requests (zone-scoped) dataset only.
• A maximum of 50 subrequests are merged per parent request. Subrequests beyond this limit are passed through unmodified as individual log entries.
• Subrequests must complete within 5 minutes of the visitor request. Subrequests that exceed this window are passed through unmodified.
• Subrequests that do not qualify appear as separate log entries — no data is lost.
• Subrequest merging is being gradually rolled out and is not yet available on all zones. Contact your account team for concerns or to ensure it is enabled for your zone. …

How to access …

R2 SQL is Cloudflare's serverless, distributed, analytics query engine for querying Apache Iceberg ↗︎ tables stored in R2 Data Catalog.

R2 SQL now supports functions for querying JSON data stored in Apache Iceberg tables, an easier way to parse query plans with EXPLAIN FORMAT JSON, and querying tables without partition keys stored in R2 Data Catalog.

JSON functions extract and manipulate JSON values directly in SQL without client-side processing:

SELECT
  json_get_str(doc, 'name') AS name,
  json_get_int(doc, 'user', 'profile', 'level') AS level,
  json_get_bool(doc, 'active') AS is_active
FROM my_namespace.sales_data
WHERE json_contains(doc, 'email')

For a full list of available functions, refer to JSON functions.

EXPLAIN FORMAT JSON returns query execution plans as structured JSON for programmatic analysis and observability integrations:

npx wrangler r2 sql query "${WAREHOUSE}" "EXPLAIN FORMAT JSON SELECT * FROM logpush.requests LIMIT 10;"

┌──────────────────────────────────────┐
│ plan                                 │
├──────────────────────────────────────┤
│ {                                    │
│   "name": "CoalescePartitionsExec",  │ …

Logpush has traditionally been great at delivering Cloudflare logs to a variety of destinations in JSON format. While JSON is flexible and easily readable, it can be inefficient to store and query at scale.

With this release, you can now send your logs directly to Pipelines to ingest, transform, and store your logs in R2 as Parquet files or Apache Iceberg tables managed by R2 Data Catalog. This makes the data footprint more compact and more efficient at querying your logs instantly with R2 SQL or any other query engine that supports Apache Iceberg or Parquet.

Transform logs before storage

Pipelines SQL runs on each log record in-flight, so you can reshape your data before it is written. For example, you can drop noisy fields, redact sensitive values, or derive new columns:

INSERT INTO http_logs_sink
SELECT
  ClientIP,
  EdgeResponseStatus,
  to_timestamp_micros(EdgeStartTimestamp) AS event_time,
  upper(ClientRequestMethod) AS method,
  sha256(ClientIP) AS hashed_ip
FROM http_logs_stream
WHERE EdgeResponseStatus >= 400;
``` …

Archive and audit security action items

Introducing enhanced archiving capabilities for security action items within the Security Overview dashboard. This update allows security teams to maintain a cleaner workspace by removing resolved, accepted, or irrelevant items from their active list while maintaining a clear paper trail for compliance.

---

Why this matters

Managing a high volume of security insights can be overwhelming. Previously, users lacked a structured way to dismiss items without losing the context of why they were ignored.

With these new archiving options—False Positive, Accept Risk, and Other—you can now suppress items indefinitely with required rationale text for risk-based decisions. This ensures that your team remains focused on critical, actionable vulnerabilities while preserving institutional knowledge for audits.

Key features

• Structured Archiving: Choose from specific categories to define why an action item is being moved.
• Required Rationale: For "Accept Risk" and "Other" categories, users must provide documentation, ensuring accountability for security decisions.
• Audit Log Transparency: New API endpoints allow you to programmatically retrieve the history of status changes and rationale for any insight at the account or zone level. …

You can now achieve higher cache HIT rates and reduce origin load for origins hosted on public cloud providers with Smart Tiered Cache. By setting a cloud region hint for your origin, Cloudflare selects the optimal upper-tier data center for that cloud region, funneling all cache MISSes through a single location close to your origin.

Previously, Smart Tiered Cache could not reliably select an optimal upper tier for origins behind anycast or regional unicast networks commonly used by cloud providers. Origins on AWS, GCP, Azure, and Oracle Cloud would fall back to a multi-upper-tier topology, resulting in lower cache HIT rates and more requests reaching your origin.

How it works

Set a cloud region hint (for example, aws/us-east-1 or gcp/europe-west1) for your origin IP or hostname. Smart Tiered Cache uses this hint along with real-time latency data to select a primary upper tier close to your cloud region, plus a fallback in a different location for resilience.

• Supported providers: AWS, GCP, Azure, and Oracle Cloud.
• All plans: Available on Free, Pro, Business, and Enterprise plans at no additional cost.
• Dashboard and API: Configure from Caching > Tiered Cache > Origin Configuration, or use the API and Terraform.
