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.

AI Analysis
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, Python libraries such as aiohttp, daphne, pillow, pyasn1, and receptor components. Arbitrary code execution is also possible via untrusted input to CookieJar.load() in aiohttp (CVE-2026-34993). The update addresses these vulnerabilities to improve the security posture of the platform.
Potential Impact
The vulnerabilities allow attackers to bypass authentication mechanisms, cause denial of service conditions, leak sensitive information, and execute arbitrary code in some cases. This could lead to unauthorized access, service disruption, and potential compromise of systems running the affected platform components. The overall security impact is rated as important by Red Hat.
Mitigation Recommendations
Red Hat has released an important security update for Ansible Automation Platform 2.6 that addresses all listed vulnerabilities. Users should apply the update following the official Red Hat Ansible Automation Platform documentation and release notes. No additional mitigation steps are indicated beyond applying the vendor-provided update.
