TL;DR

The huggingface_hub client writes Hugging Face API tokens to HF_TOKEN_PATH and multi-account tokens to HF_STORED_TOKENS_PATH under the user's cache directory. Before the fix, those files were created with default POSIX modes, often leaving token files world-readable on typical systems. A local user or process with filesystem access to the victim's home directory could read the tokens and authenticate to the Hub as that user. The fix writes secrets through _write_secret, creating parent directories at 0o700 and files at 0o600, and tightens permissions on existing paths on the next save.
