Red Hat Security Advisory: Red Hat Ansible Automation Platform 2.6 Product Security and Bug Fix Update
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): * ansible-core: argument injection in ansible-galaxy role install leads to arbitrary code execution (CVE-2026-11332) * automation-controller: Path traversal via malicious entry point name in pip wheel installation allows arbitrary file overwrite (CVE-2026-8643) * automation-controller: urllib3: Denial of Service due to excessive HTTP response decompression (CVE-2026-44432) * automation-platform-ui: fast-uri: Path traversal vulnerability allows bypass of security policies (CVE-2026-6321) * python3.12-pulpcore: relative_path_validator bypass via directory traversal in FilesystemExport (CVE-2026-12701) * receptor: golang.org/x/net/html: Cross-Site Scripting via HTML parsing bypass (CVE-2026-27136) * receptor: golang.org/x/net/html: Arbitrary code execution via Cross-Site Scripting (CVE-2026-25681) * receptor: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145) * receptor: Go net package: Denial of Service via long CNAME response in LookupCNAME (CVE-2026-33811) * receptor: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing (CVE-2026-39821) * receptor: Go crypto/x509: Denial of Service via inefficient certificate chain validation (CVE-2026-32281) For details about this release, refer to the release notes listed in the References section.

Technical Analysis
CVE-2026-6321 is a buffer overflow vulnerability in the cryptography library used by Red Hat Discovery, triggered when non-contiguous buffers are passed to certain Python APIs such as Hash.update(). This flaw can lead to a denial of service by crashing or restarting the affected service. The vulnerability has a CVSS 3.1 base score of 7.5 (high) with network attack vector, low complexity, no privileges required, and no user interaction. Red Hat products isolate affected services, limiting potential impact. A patch is available, and Red Hat has issued an official security advisory (RHSA-2026:20338) covering this and related CVEs.
Potential Impact
Exploitation of this vulnerability can cause a denial of service by crashing or restarting the affected service process. Due to Red Hat's default isolation of service processes, the impact is limited to the compromised service account without broader system access. There is no indication of confidentiality or integrity loss beyond the service scope. No known exploits are reported in the wild.
Mitigation Recommendations
A patch is available for this vulnerability as indicated by Red Hat's security advisory RHSA-2026:20338. Users should apply the official updates provided by Red Hat to affected products. No alternative mitigations are noted or recommended by Red Hat. The advisory emphasizes installing updated containers via discovery-installer RPM and following official documentation for deployment.
