💬 Slack Integration — Alert Channel Destinations

Alerts can now reach Slack. Connect a Slack workspace from the Integrations page, authorize one or several destination channels (the connection check confirms each channel with a one-time message and names any channel Slack refuses), and pick those channels in the alert modal's "Destination channels" selector, next to the "Recipients" selector for email. The alerts list summarizes both in a single "Destinations" column, showing a rule's email recipients and Slack channels at a glance. Disconnecting the workspace and recovering from revoked credentials are handled from the same page.

Read more in the Slack integration documentation and the Alerts documentation.

🤖 Lighthouse AI — Answer Feedback

Every Lighthouse AI answer can now be rated with a 👍 or 👎, with an optional field to describe what worked or what did not. Feedback is collected per answer, directly in the chat, and tells the team where Lighthouse should improve next.

Read more in the Lighthouse AI documentation.

📥 Providers — Imported Findings Indicator

Providers whose findings were imported with the Prowler CLI now show an "Imported provider" indicator next to their connection status in the providers table. In accounts that mix connected providers with Import Findings uploads, the table now tells them apart at a glance.

Read more in the Import Findings documentation.

📚 Compliance — NCSC Cyber Essentials 3.3

Cyber Essentials is the UK National Cyber Security Centre (NCSC) scheme certifying the baseline technical controls an organization must implement, and cloud services are explicitly in scope and cannot be excluded from an assessment. Prowler now includes NCSC Cyber Essentials: Requirements for IT Infrastructure v3.3 (April 2026) as a universal framework, with its 28 requirements organized in the five control themes: Firewalls, Secure Configuration, Security Update Management, User Access Control, and Malware Protection.

Sixteen requirements map to Azure checks covering the controls the applicant organization owns under the shared responsibility model. The remaining twelve apply to end-user devices, on-premises network appliances, or organizational process, which cloud control-plane evidence cannot observe, so they are reported as Manual.

🔍 Checks

Fifteen new checks land across seven providers in this release.

AWS

• ecr_repository_image_no_secrets scans the latest image of each ECR repository, both its configuration and its filesystem layers, for hardcoded secrets. Thanks to @esquaredsec!
• Four new Amazon Bedrock checks, thanks to @tamg-aws!
  • bedrock_guardrail_contextual_grounding_filter_enabled verifies that guardrails enable both contextual grounding filters, blocking responses that are not supported by the retrieved source or do not answer the question asked.
  • bedrock_custom_model_encrypted_with_cmk verifies that custom models are encrypted at rest with a customer-managed KMS key instead of an AWS-owned key the organization cannot audit, rotate, or revoke.
  • bedrock_knowledge_base_encrypted_with_cmk verifies that each knowledge-base data source encrypts with a customer-managed KMS key the transient storage used while documents are chunked and embedded.
  • bedrock_agent_role_not_shared_across_agents verifies that every agent has a dedicated execution role, so no agent inherits another's permissions.
• rolesanywhere_profile_restricts_session_permissions flags IAM Roles Anywhere profiles that reference an administrative role without scoping down the vended session with a session policy or managed policies.

Explore all AWS checks at Prowler Hub.

GCP

• iam_workload_identity_pool_provider_attribute_condition flags Workload Identity Federation providers that trust a multi-tenant issuer without an attribute condition restricting which external identities can impersonate federated principals.

GitHub

Three new checks harden GitHub Actions defaults, all contributed by @Edneam. Thank you!

• organization_default_workflow_permissions_read_only and repository_default_workflow_permissions_read_only verify that workflows get a read-only default GITHUB_TOKEN at the organization and repository level.
• organization_actions_pull_request_approval_disabled verifies that organizations prevent GitHub Actions from creating and approving pull requests.

Microsoft 365

• defender_domain_dmarc_records_published checks that every Exchange Online domain publishes a DMARC record with an enforcing policy (p=quarantine or p=reject). Thanks to @Rishi943!

Alibaba Cloud

• oss_bucket_versioning_enabled verifies that OSS buckets keep versioning enabled, allowing recovery from accidental or malicious object overwrite and deletion. Thanks to @abidedavana!
• oss_bucket_server_side_encryption_enabled verifies that OSS buckets define a default server-side encryption rule, either AES256 or KMS. Thanks to @alexchen-sys!

OSS bucket logging, versioning, default encryption, and ACL configurations are also now read correctly from the Alibaba Cloud SDK, so the checks reading them no longer report every bucket as unconfigured.

Huawei Cloud

• vpc_security_group_open_egress flags VPC security groups that allow open egress to the internet. Thanks to @tomitobio!

Explore all Huawei Cloud checks at Prowler Hub.

STACKIT

• ske_cluster_no_public_endpoint flags SKE clusters whose Kubernetes API endpoint is reachable from the whole internet, because the ACL extension is disabled or its allowed CIDR list contains 0.0.0.0/0 or ::/0. Thanks to @johannes-engler-mw!

UI

🚀 Added

• NCSC Cyber Essentials 3.3 compliance support with its dedicated mapper, details panel, and icon (#11588)
• Thumbs-up and thumbs-down feedback form for Lighthouse assistant answers with optional details (#12419)
• Display the default one-scan free trial and trial expiration in the existing sidebar banner (#12420)
• Slack integration: connect a Slack workspace from the Integrations page (Prowler Cloud only) (#12435)
• Prowler Cloud indicator for providers created via Import Findings alongside every connection status (#12447)

• Cancelled-subscription variant in the sidebar trial banner (Prowler Cloud only) (#12538)

🔄 Changed

🐞 Fixed

• Scan auto-refresh no longer overlaps slow client refreshes and now signals when scan execution settles (#12455)
• The compliance "Across providers" section builds its framework list from the API catalog instead of a hardcoded set of ids, so a universal framework registered by an installed package renders like a shipped one (#12536)
• The compliance "Across providers" section reports a failed catalog request instead of rendering the "no data yet" empty state (#12536)
• Returning from Slack after approving the install now reliably lands on the Slack integration page instead of getting stuck on the callback screen (Prowler Cloud only) (#12572)

🔐 Security

• libcrypto3 and libssl3 upgraded to 3.5.8-r0 in the UI container image, patching seven high OpenSSL CVEs (#12549)

API

🐞 Fixed

• FINDINGS_TABLE_PARTITION_MAX_AGE_MONTHS is now applied in months instead of days, and negative values are rejected (#12580)

🔐 Security

• openssl, libssl3t64 and openssl-provider-legacy upgraded to 3.5.7-1~deb13u2 in the API container image, patching ten high OpenSSL CVEs (#12549)

SDK

🚀 Added

• NCSC Cyber Essentials 3.3 compliance framework with Azure provider coverage across the five Cyber Essentials themes (#11588)
• oss_bucket_versioning_enabled check for Alibaba Cloud provider, verifying that OSS buckets have versioning enabled to allow recovery from accidental or malicious object overwrite and deletion (#11913)
• defender_domain_dmarc_records_published checks that every Exchange Online domain publishes a DMARC record with an enforcing policy (p=quarantine or p=reject) (#11936)
• ske_cluster_no_public_endpoint check for STACKIT provider, flagging SKE clusters whose Kubernetes API endpoint is reachable from the whole internet because the ACL extension is disabled or its allowed CIDR list contains 0.0.0.0/0 or ::/0 (#11943)
• oss_bucket_server_side_encryption_enabled check for Alibaba Cloud provider, verifying that OSS buckets have a default server-side encryption rule (AES256 or KMS) (#11981)
• organization_default_workflow_permissions_read_only check for GitHub provider, verifying that organizations grant GitHub Actions workflows a read-only default GITHUB_TOKEN (#12122)
• ecr_repository_image_no_secrets check for AWS provider, scanning the latest ECR repository image's configuration and filesystem layers for hardcoded secrets (#12123)
• repository_default_workflow_permissions_read_only check for GitHub provider, verifying that repositories grant GitHub Actions workflows a read-only default GITHUB_TOKEN (#12143)
• vpc_security_group_open_egress check for Huawei Cloud provider: VPC security groups do not allow open egress to the internet (#12209)
• organization_actions_pull_request_approval_disabled check for GitHub provider, verifying that organizations prevent GitHub Actions from creating and approving pull requests (#12394)
• Add the iam_workload_identity_pool_provider_attribute_condition check to flag GCP Workload Identity Federation providers that trust a multi-tenant issuer without an attribute condition restricting which external identities can impersonate federated principals (#12416)
• Add the rolesanywhere_profile_restricts_session_permissions check to flag AWS IAM Roles Anywhere profiles that reference an administrative role without scoping down the vended session with a session policy or managed policies (#12416)
• bedrock_guardrail_contextual_grounding_filter_enabled, bedrock_custom_model_encrypted_with_cmk, bedrock_knowledge_base_encrypted_with_cmk and bedrock_agent_role_not_shared_across_agents are four new AWS Bedrock checks covering guardrail contextual grounding, custom model encryption, knowledge-base data-source encryption, and non-shared agent execution roles. (#12459)
• Cluster column in Kubernetes CIS, ISO27001, Prowler ThreatScore, and universal compliance outputs, populated with the resolved cluster name so multi-cluster scans can be told apart in the output (#12506)

🐞 Fixed

• Kubernetes kubelet checks no longer disappear from the scan with TypeError: 'NoneType' object is not iterable when a kubelet-config ConfigMap is broken: one with malformed YAML is logged and skipped while the valid ones are still evaluated, one without kubelet data is evaluated with an empty configuration instead of crashing the checks, and the apiserver, controllermanager, etcd and scheduler pod gatherers now always return a list (#12225)
• IaC provider now raises typed IacBaseException errors (repository clone, Trivy missing, scan and output processing failures) instead of calling sys.exit(1); the CLI still stops with the logged message, and API scans fail as regular task errors instead of a SystemExit escaping the worker (#12227)
• CLI Slack integration (--slack) no longer fails when a scan produces no findings: the pass and fail percentages are guarded against a findings_count of 0, which previously raised ZeroDivisionError and sent blocks=None to Slack instead of the summary (#12229)
• AWS FSBP compliance mapping for IAM.9 and EKS.1 referenced missing/renamed checks; both now point to their real, existing check IDs (#12372)
• ec2_securitygroup_not_used no longer reports a false positive for security groups attached only to an AWS Batch compute environment, which holds them in configuration without creating a network interface while scaled down to zero instances (#12458)
• Bedrock Agent ARNs are now built from the audited partition instead of a hardcoded arn:aws:, so findings in GovCloud and China carry a resolvable ARN and --resource-arn scoping matches agents in those partitions. (#12459)
• push-to-cloud now validates Private Cloud TLS certificates with the operating system trust store without changing provider HTTP clients (#12485)
• prowler.compliance.universal entry point directories are resolved through a single shared helper and deduplicated by resolved path, so a directory reached through two entry points is parsed once and a package that fails to import no longer hides the rest (#12536)
• OSS bucket logging, versioning, default encryption and ACL configurations are now read correctly from the Alibaba Cloud SDK, so oss_bucket_logging_enabled, oss_bucket_versioning_enabled, oss_bucket_server_side_encryption_enabled and oss_bucket_not_publicly_accessible no longer report every bucket as unconfigured (#12546)

🔐 Security

• openssl, libssl3t64 and openssl-provider-legacy upgraded to 3.5.7-1~deb13u2 in the SDK container image, patching ten high OpenSSL CVEs (#12549)

MCP

🚀 Added

• Failures shared by every tool - a rejected credential, a missing permission, a rate limit, an outage, an unreachable API, a bad argument - are now explained with a message that says what went wrong and what to do about it (#12531)

🐞 Fixed

• prowler_docs_search returns results again: it calls the search endpoint docs.prowler.com moved to, since the one it used no longer exists, and each result now names the page's title, the section it matched and a URL anchored at that section (#12578)

🔐 Security

• Stop relaying upstream response bodies to agents: a failed request now reaches the caller as a sentence this server wrote, with the full body kept to the logs, so a gateway error page or a debug traceback can no longer be replayed into a model's context (#12531)
• sqlite-libs upgraded to 3.53.4-r0 in the container image, patching CVE-2026-11822 and CVE-2026-11824 (#12537)
• libcrypto3 and libssl3 upgraded to 3.5.8-r0 in the container image, patching CVE-2026-14456 (#12547)
