      <title>CVE-2026-84716 — Automation-controller: automation-controller: instance install_bundle issues 10-year, non-revocable receptor mesh-ca ce…</title>
      <link>https://vulnerability.circl.lu/vuln/cve-2026-84716</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9, Red Hat Ansible Automation Platform 2.6 for RHEL 9, Red Hat Ansible Automation Platform 2.6, Red Hat Ansible Automation Platform 2.7&lt;/p&gt;
&lt;p&gt;A flaw was found in the automation-controller instance
                  install-bundle endpoint. When a System Administrator downloads
                  an execution/hop node&amp;#39;s install bundle, the controller signs an
                  X.509 certificate with the receptor mesh certificate authority
                  in which the Common Name, DNS subject-alternative-name, and
                  receptor node-id are taken verbatim from the caller-chosen
                  instance hostname, with a hard-coded ten-year validity, a random
                  serial, and no issuance log or revocation list. Because the
                  hostname charset validator is case-insensitive while the
                  uniqueness validator is case-sensitive, an administrator can
                  register a case variant of an existing control node&amp;#39;s hostname
                  and obtain a mesh-CA-signed certificate that TLS peers, which
                  match hostnames case-insensitively, accept as that control node.
                  In managed/hosted deployments — where the customer holds
                  controller superuser but the platform operator runs the mesh —
                  this yields a long-lived, non-revocable mesh peer credential and,
                  with an on-path position, TLS impersonation or interception of
                  control/hybrid mesh nodes. It does not grant direct remote code
