RHEL 10 / 9 : Red Hat Ansible Automation Platform 2.7 Product Security and Bug Fix Update (Important) (RHSA-2026:42080)

high Nessus Plugin ID 328030

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:42080 advisory.

 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)
 * receptor: golang.org/x/net/html: Cross-Site Scripting via HTML parsing bypass (CVE-2026-27136)
 * receptor: golang crypto/x509: Denial of Service via excessive processing of DNS SAN entries (CVE-2026-27145)
 * receptor: golang.org/x/net/idna: Privilege escalation via incorrect Punycode label processing (CVE-2026-39821)

 For details about this release, refer to the release notes listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected ansible-core and / or receptor packages.
