The npm package dolyame-ui-pageheader version 35.8.1 contains malicious code that executes a platform-specific binary fetched from remote Cloudflare worker endpoints. Upon installation or requiring the package, it downloads an opaque binary payload, writes it to a temporary directory with disguised filenames, sets executable permissions, and spawns it detached without any verification. This behavior results in full remote code execution on the host system controlled by the operator of the remote endpoints.
