CVE-2026-66067

RabbitMQ is a messaging and streaming broker. Prior to versions 4.2.7 and 4.3.1, The stream open handler calls only checkvhostaccess; it omits the node/vhost/user connection-limit checks that rabbitreader performs for AMQP. A developer %% FIXME comment at the cited line explicitly acknowledges th...

automation-controller: automation-controller-container: automation-controller: JobJobEventsChildrenSummary RBAC bypass exposes cross-tenant job event tree structure

JobJobEventsChildrenSummary view has no model/parentmodel. ModelAccessPermission.checkgetpermissions falls through returns True for any authenticated user. The view uses raw getobjector404Job, pk without DRF object-level permission check. Zero-privilege user reads event tree structure,...

automation-controller: automation-controller-container: automation-controller: missing use_role authorization on the project signature validation credential foreign key allows a project administrator to bind and use another organization's credential cross-tenant

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. A project has a signature validation credential foreign key used to validate signed project content. Unlike the project's SCM credential, the authorization logic does not verify that the requesting user has use...

automation-controller: automation-controller-container: automation-controller: organization galaxy credential attachment checks only read permission on the credential, allowing an organization admin with read-only visibility to bind and server-side-use another tenant's Automation Hub API token

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. When attaching a Galaxy or Automation Hub credential to an organization through the galaxycredentials relationship endpoint, the controller verifies only that the requesting user can read the credential, rather than...

automation-controller: automation-controller-container: automation-controller: host_filter SmartFilter ORM traversal exposes JobEvent/AdHocCommandEvent event_data and stdout to users without permission on the job, enabling blind character-by-character extraction of job output (cross-tenant information disclosure)

A flaw was found in Red Hat Ansible Automation Platform's automation-controller. The hostfilter query parameter on the hosts list API is parsed into a raw Django ORM filter whose lookup path is validated only against a sensitive-field blocklist, with no authorization check on the database relatio...

automation-controller: automation-controller-container: automation-controller: constructed inventory input inventory attachment checks only read permission on the source inventory, allowing a read-only user to clone another tenant's hosts and secrets and run ad hoc commands against them

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. When attaching a source inventory to a constructed inventory through the inputinventories relationship endpoint, the controller verifies only that the requesting user can read the source inventory, rather than that...

automation-controller: automation-controller-container: automation-controller: execution environment credential foreign key is not use-permission checked, allowing an organization execution-environment admin to bind and disclose another organization's container registry credential (cross-tenant credential disclosure)

A flaw was found in Red Hat Ansible Automation Platform's automation-controller. When creating or editing an execution environment, the controller does not verify that the requesting user has use permission on the container registry credential referenced by the execution environment; it validates...

automation-controller: automation-controller-container: automation-controller: workflow job template node execute permission check bypassed by creating a node with a null unified_job_template and then patching it, allowing a single workflow-admin to execute any other tenant's job template with the victim's credentials (cross-tenant privilege escalation)

A flaw was found in Red Hat Ansible Automation Platform's automation-controller. The execute-permission check on a workflow job template node's unified job template is skipped when the node's currently stored unified job template is empty: the check inspects only the existing value, not the...

automation-controller: automation-controller-container: automation-controller: Named-URL 404 body oracle enables cross-tenant resource name enumeration

URLModificationMiddleware resolves named-URL lookups against unfiltered Model.objects before RBAC. The 403→404 shim only rewrites 403 responses, leaving the pk=0 miss path with a different 404 detail string. Differential "Not found." vs "No matches..." reveals whether a named resource org,...

automation-controller: automation-controller-container: automation-controller: constructed inventory input inventory attachment checks only read permission on the source inventory, allowing a read-only user to clone another tenant's hosts and secrets and run ad hoc commands against them

A flaw was found in Red Hat Ansible Automation Platform's automation- controller. When attaching a source inventory to a constructed inventory through the inputinventories relationship endpoint, the controller verifies only that the requesting user can read the source inventory, rather than that...

CVE-2026-66076

RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0, isauthorized/2 calls rabbitmgmtutil:isauthorized/2, which checks only the management tag, instead of isauthorizedvhost/2. The /api/queues/quorum/:vhost/:queue/status handler reads the vhost...

CVE-2026-66067

Prior to versions 4.2.7 and 4.3.1 , RabbitMQ fails to correctly enforce per-user and per-virtual host (vhost) connection limits within its stream protocol handler. While the handler performs check_vhost_access, it omits the connection-limit checks used for AMQP, a gap explicitly acknowledged in t...

CVE-2026-67220 RabbitMQ: JMS topic exchange erl_scan atom exhaustion

RabbitMQ is a messaging and streaming broker. Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, 4.3.0, When a binding is created on an x-jms-topic exchange, addbinding/3 reads the rjmserlangselector argument and passes it through erlscan:string/1 then erlparse:parseterm/1. erlscan:string/1 intern...

CVE-2026-67220

Prior to versions 3.13.15, 4.0.20, 4.1.11, 4.2.6, and 4.3.0 , RabbitMQ is vulnerable to a cross-tenant Denial of Service (DoS) due to atom exhaustion. When creating a binding on an x-jms-topic exchange , the add_binding/3 function processes the rjms_erlang_selector argument using erl_scan:string/...
