Red Hat Ansible Automation Platform provides an enterprise framework for building, deploying and managing IT automation at scale. IT Managers can provide top-down guidelines on how automation is applied to individual teams, while automation developers retain the freedom to write tasks that leverage existing knowledge without the overhead. Ansible Automation Platform makes it possible for users across an organization to share, vet, and manage automation content by means of a simple, powerful, and agentless language. Security Fix(es): * automation-controller: Account hijacking and unauthorized access via unverified email linking (CVE-2026-6266) * automation-controller: DTLS cookie callback buffer overflow (CVE-2026-27459) * automation-controller: PyJWT accepts unknown `crit` header extensions (RFC 7515 §4.1.11 MUST violation) (CVE-2026-32597) * automation-controller: denial of service via malformed HTML-like sequences (CVE-2025-69534) * automation-gateway: Account hijacking and unauthorized access via unverified email linking (CVE-2026-6266) * automation-gateway-proxy: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679) * automation-platform-ui: Rollup: Remote Code Execution via Path Traversal Vulnerability (CVE-2026-27606) * automation-platform-ui: minimatch: Denial of Service via specially crafted glob patterns (CVE-2026-26996) * python3.12-django-ansible-base: Account hijacking and unauthorized access via unverified email linking (CVE-2026-6266) * python3.12-markdown: denial of service via malformed HTML-like sequences (CVE-2025-69534) * python3.12-jwcrypto: JWCrypto: Memory exhaustion via crafted compressed JWE tokens (CVE-2026-39373) * python3.12-pyasn1: pyasn1 Vulnerable to Denial of Service via Unbounded Recursion (CVE-2026-30922) * python3.12-pyasn1: pyasn1: Denial of Service due to memory exhaustion from malformed RELATIVE-OID (CVE-2026-23490) * python3.12-pyOpenSSL: DTLS cookie callback buffer overflow (CVE-2026-27459) * receptor: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-6266 is a vulnerability in Red Hat Ansible Automation Platform 2.5 and 2.6 where the user auto-link strategy introduced in version 2.6 automatically links an external Identity Provider (IDP) identity to an existing user account based on email matching without verifying email ownership. This flaw allows a remote attacker to potentially hijack victim accounts or gain unauthorized access to other accounts, including administrative ones, by manipulating the IDP-provided email. The vulnerability has a CVSS score of 8.3 (high severity). Red Hat has released security updates for Ansible Automation Platform 2.5 and 2.6 to address this issue.
