Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Talos Linux support bundles generated by talosctl support include registry authentication credentials from RegistryAuthConfig resources, in the registryconfigs and etcfilespecs files. The Go module github.com/siderolabs/talos is affected before 1.14.0-alpha.0.0.20260513110206-76080416beee, and that version is listed as the fix. An attacker would need access to a support bundle that someone shared publicly, such as on a forum or issue tracker, and could then use the exposed credentials against the private registry. The source notes that Talos 1.14 and later encrypt support bundles by default.
