CVE-2026-75887: Red Hat OpenShift console path traversal in locale handler

CVE-2026-75887 · Severity: high · CVSS 7.5 · Published 2026-09-23

The OpenShift console, a web-based interface for managing containerized applications, contains a path traversal vulnerability that allows unauthenticated attackers to read sensitive configuration and plugin files from the container filesystem. An attacker can manipulate query parameters to bypass directory restrictions and access arbitrary JSON files, potentially exposing credentials, API keys, and other sensitive data stored in the pod environment.

Technologies: Red Hat OpenShift Container Platform. Vendors: Red Hat.

Technical details

A path traversal flaw exists in the /locales/resource.json endpoint of the OpenShift console's internationalization (i18n) handler, where the lng and ns query parameters are not properly validated. An unauthenticated network attacker can inject path traversal sequences to read arbitrary .json files from the pod filesystem and potentially exploit registered dynamic-plugin backends, resulting in information disclosure without requiring authentication or user interaction.
