high Nessus Plugin ID 301388

Synopsis

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

Description

The remote Redhat Enterprise Linux 8 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:3959 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.

 * automation-controller: wheel: Privilege Escalation or Arbitrary Code Execution via malicious wheel file unpacking (CVE-2026-24049)
 * automation-controller: pyasn1 has a DoS vulnerability in decoder (CVE-2026-23490)
 * automation-gateway: React Router vulnerable to XSS via Open Redirects (CVE-2026-22029)
