Red Hat Security Advisory: Red Hat Ansible Automation Platform 2.5 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-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 PCF font data (CVE-2026-54059) * 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 BDF font file (CVE-2026-55379) * python3.12-pillow: Denial of Service via crafted GD 2.x image file (CVE-2026-55380) * 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-2026-59885) * python3.12-pyasn1: Denial of Service via crafted ASN.1 OBJECT IDENTIFIER (CVE-2026-59886) * receptor: quic-go: Denial of Service via excessive memory allocation in HTTP/3 trailers (CVE-2026-40898) * receptor: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145) 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 vulnerabilities in Red Hat Ansible Automation Platform 2.5, including CVE-2026-12383 where the ExternalEventStreamViewSet in automation-eda-controller trusts the Subject header without validation, leading to information leakage. Other vulnerabilities include authentication bypass in automation-controller due to forged JSON Web Tokens (CVE-2026-48526), denial of service issues in Go net package, Python libraries (aiohttp, daphne, pillow, pyasn1), and receptor components. The issues range from authentication bypass, denial of service, to arbitrary code execution. Red Hat has issued patches for these vulnerabilities in the 2.5 release series for RHEL 8 and 9 architectures.
Potential Impact
The vulnerabilities collectively allow attackers to bypass authentication, cause denial of service conditions, leak sensitive information, and execute arbitrary code within the affected platform. This could lead to unauthorized access, service disruption, and potential compromise of automation workflows managed by the platform.
Mitigation Recommendations
Red Hat has released an important security update for Ansible Automation Platform 2.5 that addresses these vulnerabilities. Users should apply the update as documented in the official Red Hat Ansible Automation Platform 2.5 release notes and documentation. No additional mitigations are specified beyond applying the vendor-provided patches.
