CVE-2026-77564

Description

Talos Linux is a Linux distribution built for Kubernetes deployments. Prior to 1.12.9 and 1.13.3, talosctl support includes the auth field from resources/registryconfigs.cri.talos.dev.yaml and sensitive content from etcfilespecs.files.talos.dev.yaml in generated support bundles instead of marking or redacting those resources. An operator who shares a bundle with an unintended party can therefore disclose private registry authentication parameters, with impact depending on the registry's network exposure and credential privileges. Talos 1.14 and later encrypt support bundles by default, which reduces but does not replace the need for redaction. This issue is fixed in versions 1.12.9 and 1.13.3.
