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 fixes in Red Hat Ansible Automation Platform 2.6, including CVE-2026-6266 (account hijacking via unverified email linking), CVE-2026-27459 (DTLS cookie callback buffer overflow), CVE-2026-32597 (PyJWT accepting unknown critical header extensions violating RFC 7515), CVE-2025-69534 (denial of service via malformed HTML-like sequences), CVE-2026-25679 (incorrect parsing of IPv6 host literals), CVE-2026-27606 (remote code execution via path traversal), CVE-2026-26996 (denial of service via crafted glob patterns), and others affecting Python libraries such as pyasn1, jwcrypto, and pyOpenSSL. These vulnerabilities collectively impact authentication, input validation, memory management, and parsing logic within the platform and its dependencies. The advisory references an important security update that addresses these issues in the affected versions.
Potential Impact
The vulnerabilities can lead to unauthorized account access (account hijacking), denial of service conditions through malformed inputs or resource exhaustion, remote code execution via path traversal, and memory corruption due to buffer overflows. These impacts affect the confidentiality, integrity, and availability of the Ansible Automation Platform environment. Exploitation could allow attackers to bypass authentication controls, disrupt automation workflows, or execute arbitrary code within the affected components.
Mitigation Recommendations
Red Hat has released an important security update for Ansible Automation Platform 2.6 that addresses these vulnerabilities. Users should apply the update as per the official Red Hat advisory RHSA-2026:13508 and follow the Ansible Automation Platform documentation for upgrade instructions. No additional mitigation steps are indicated beyond applying the official patch. Patch status is confirmed by the vendor advisory.
