- Remediation
- <![CDATA[ ## Remediation Suggestions 1. Change the default provider to a local implementation such as Ollama. Cloud embeddings should require explicit opt-in: ```python "provider": os.getenv("MEMORY_CORE_EMBEDDING_PROVIDER", "ollama"), "base_url": os.getenv("MEMORY_CORE_EMBEDDING_BASE_URL", "http://localhost:11434"), ``` 2. Do not automatically reuse credentials from `~/.openclaw/openclaw.json` unless the user has explicitly enabled cloud embeddings for this Skill. 3. Before the first cloud request, clearly disclose: - The destination provider and hostname. - That raw memory or query text will be transmitted. - The maximum transmitted input length. - Whether provider-side retention or logging may apply. 4. Require an explicit configuration value such as `allow_remote_embedding: true`; fail closed when a remote provider is selected without this consent. 5. Add optional local redaction for common sensitive values, including access tokens, passwords, private keys, email addresses, and financial identifiers. 6. Replace silent exception handling with an explicit error or a visible warning. Do not silently switch vector-generation algorithms because this conceals network failures and can degrade retrieval integrity. 7. Update `README.md` and `SKILL.md` to remove the claim that data does not leave the machine by default unless the implementation is changed to a local default. 8. Add tests confirming that: - No network request occurs under the default configuration. - Cloud requests require explicit opt-in. - Auto-discovered credentials are not used without consent. - Logs and error messages never expose bearer credentials. ]]>
