Description

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: 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-controller: cryptography Subgroup Attack Due to Missing Subgroup Validation for SECT Curves (CVE-2026-26007) * automation-gateway: Account hijacking and unauthorized access via unverified email linking (CVE-2026-6266) * automation-gateway: Rollup: Remote Code Execution via Path Traversal Vulnerability (CVE-2026-27606) * automation-gateway: SVGO: Denial of Service via XML entity expansion (CVE-2026-29074) * automation-gateway: ReDoS via $data reference (CVE-2025-69873) * automation-gateway-proxy: Incorrect parsing of IPv6 host literals in net/url (CVE-2026-25679) * 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 Analysis

This advisory covers a set of security vulnerabilities in Red Hat Ansible Automation Platform 2.5, including CVE-2025-69534 (denial of service via malformed HTML-like sequences), CVE-2026-6266 (account hijacking via unverified email linking), CVE-2026-27606 (remote code execution via path traversal), and others affecting components such as automation-controller, automation-gateway, python3.12 libraries, and receptor. The vulnerabilities involve issues like improper input validation, missing subgroup validation in cryptography, acceptance of unknown JWT header extensions violating RFC 7515, and buffer overflows. The advisory references an official Red Hat update (RHSA-2026:13512) that provides fixes for these issues across multiple architectures and RHEL versions.

Potential Impact

The vulnerabilities allow attackers to perform unauthorized account hijacking, 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 2.5. No known exploits in the wild have been reported at the time of this advisory.

Mitigation Recommendations

An official security update is available from Red Hat as detailed in advisory RHSA-2026:13512. Users should apply the provided patches and updates to Red Hat Ansible Automation Platform 2.5 for RHEL 8 and 9 as soon as possible. For detailed instructions, refer to the Red Hat Ansible Automation Platform documentation and release notes. No additional mitigation steps are indicated beyond applying the official fixes.
