CVE-2026-75887
Openshift/console: openshift/console: unauthenticated path traversal in i18n locale handler
Description
A flaw was found in the OpenShift console. An unauthenticated attacker can exploit a path traversal vulnerability by manipulating the `lng` and `ns` query parameters in the `/locales/resource.json` endpoint. This allows the attacker to read sensitive `*.json` files from the pod filesystem, including plugin manifests and configuration files. Furthermore, this flaw can enable path traversal against registered dynamic-plugin backends.
