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: PyJWT: Authentication bypass due to forged JSON Web Tokens (CVE-2026-48526) * automation-eda-controller: ExternalEventStreamViewSet trusts Subject header without validation and leaks expected DN (CVE-2026-12383) * automation-eda-controller: Authentication bypass in Event-Driven Ansible via forged HTTP header (CVE-2026-18141) * automation-gateway-proxy: Go net package: Denial of Service via long CNAME response in LookupCNAME (CVE-2026-33811) * python3.12-aiohttp: Arbitrary code execution via untrusted input to CookieJar.load() (CVE-2026-34993) * python3.12-daphne: daphne: Denial of Service via excessive WebSocket message size (CVE-2026-44545) * python3.12-pillow: Denial of Service via crafted GD 2.x image file (CVE-2026-55380) * python3.12-pillow: Denial of Service via crafted BDF font file (CVE-2026-55379) * python3.12-pillow: Denial of Service via excessive memory allocation when processing font files (CVE-2026-54060) * python3.12-pillow: Denial of Service via crafted PCF font data (CVE-2026-54059) * python3.12-pillow: Native heap out-of-bounds write (CVE-2026-59197) * python3.12-pyasn1: Denial of Service via crafted ASN.1 REAL values (CVE-2026-59886) * python3.12-pyasn1: Denial of Service via crafted ASN.1 OBJECT IDENTIFIER (CVE-2026-59885) * receptor: quic-go: Denial of Service via excessive memory allocation in HTTP/3 trailers (CVE-2026-40898) 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 flaws in Red Hat Ansible Automation Platform 2.6 and its dependencies. Key issues include authentication bypass via forged JSON Web Tokens (CVE-2026-48526) and forged HTTP headers (CVE-2026-18141), information leakage due to unvalidated Subject headers (CVE-2026-12383), denial of service vulnerabilities in Go net package, python3.12 libraries (aiohttp, daphne, pillow, pyasn1), and receptor's quic-go implementation. Additionally, an arbitrary code execution vulnerability exists in python3.12-aiohttp via untrusted input to CookieJar.load(). These vulnerabilities collectively impact authentication, input validation, memory handling, and resource exhaustion. The advisory references 14 CVEs and provides fixes for Red Hat Ansible Automation Platform 2.6 on RHEL 9 and 10 across multiple architectures.
Potential Impact
The vulnerabilities can lead to authentication bypass allowing unauthorized access, information leakage of expected distinguished names, denial of service through resource exhaustion or malformed inputs, and arbitrary code execution in affected components. These impacts can disrupt automation workflows, compromise system integrity, and potentially allow attackers to execute unauthorized actions within the Ansible Automation Platform environment.
Mitigation Recommendations
Red Hat has released security updates for Ansible Automation Platform 2.6 addressing these vulnerabilities. Users should apply the official patches provided in the Red Hat advisory RHSA-2026:50336. Detailed upgrade instructions are available in the Ansible Automation Platform documentation. No additional mitigations are indicated beyond applying the vendor-provided updates.
