PostCSS takes a CSS file and provides an API to analyze and modify its rules by transforming the rules into an Abstract Syntax Tree. Prior to 8.5.19, if from is unset, an attacker can cause PreviousMap.loadFile() to read an unintended source-map file by supplying an absolute or directory-traversal sourceMappingURL. The resulting map’s sources and sourcesContent may then be exposed to the application. This issue is fixed in version 8.5.19.

The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:68334 advisory.

    Red Hat Edge Manager (RHEM) provides simple, scalable, and security-focused     management of edge devices and applications. It supports image-mode RHEL and     container workloads that run on Podman/Docker or Kubernetes.

    RHEM is now available as a standalone feature, providing greater flexibility for     edge deployments. In addition to the standalone version, RHEM continues to be     offered as a plugin for the following platforms:

    Red Hat Advanced Cluster Management (RHACM): Extends fleet management to edge     devices.
    Red Hat Ansible Automation Platform (AAP): Integrates edge management with     Ansible automation.

    This integration enables organizations to optimize the management and     orchestration of their fleets of edge devices; whether its thousands of     dispersed retail point-of-sale systems or industrial machinery on remote factory     floors.

    Value for customers and partners:

    * This solution not only helps customers manage thousands of devices but helps     scale operations.
    * To manage large-scale deployments, customers need to be able to integrate with     their existing management systems, support remote configuration and over-the-air     updates, and collect telemetry data for advanced analytics.
    * Red Hat Edge Manager offers a simple and security-focused lifecycle     management, from onboarding to decommissioning of edge devices.

    This complete end-to-end solution empowers organizations to gain the most value     from the fleets of devices that generate data, all from a centralized location.
