Red Hat Security Advisory: Red Hat Ansible Automation Platform 2.6 Product Security and Bug Fix Update
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.

Technical Summary
This advisory covers multiple security vulnerabilities in Red Hat Ansible Automation Platform 2.6 and related components. Key issues include account hijacking and unauthorized access via unverified email linking (CVE-2026-6266), a DTLS cookie callback buffer overflow (CVE-2026-27459), PyJWT accepting unknown critical header extensions violating RFC 7515 (CVE-2026-32597), denial of service via malformed HTML-like sequences (CVE-2025-69534), remote code execution through path traversal in automation-platform-ui (CVE-2026-27606), and denial of service via crafted glob patterns (CVE-2026-26996). Additional vulnerabilities affect Python libraries such as pyasn1, jwcrypto, and pyOpenSSL, causing denial of service or memory exhaustion. The issues collectively pose risks of unauthorized access, service disruption, and remote code execution. Red Hat has released patches addressing these vulnerabilities in the Ansible Automation Platform 2.6 update for RHEL 9 and 10.
Potential Impact
The vulnerabilities allow attackers to perform account hijacking and unauthorized access, cause denial of service conditions through malformed inputs or resource exhaustion, and execute remote code via path traversal. These impacts can compromise the confidentiality, integrity, and availability of the affected systems running Red Hat Ansible Automation Platform 2.6. The presence of remote code execution and account hijacking vulnerabilities indicates a high risk of system compromise if exploited.
Mitigation Recommendations
Red Hat has released an official security update for Ansible Automation Platform 2.6 addressing these vulnerabilities. Users should apply the update as documented in the Red Hat advisory RHSA-2026:13508 and the Ansible Automation Platform 2.6 release notes. No additional mitigation steps are indicated beyond applying the official patches. Patch status is confirmed by the vendor advisory.
