Encrypted only. Public PGP key in frontend/pgp.txt.
Important for adopters: the PGP key shipped in this repo is a <YOUR-PGP-FINGERPRINT> placeholder. Generate your own key before running an instance, replace frontend/pgp.txt, and update the fingerprint references in frontend/terms.html + frontend/docs.html.
Anything that could:
- Log or persist a customer's IP address, prompt content, completion content, or API key plaintext
- Allow an attacker to claim an API key issued to another customer
- Bypass the per-key credit decrement (free inference)
- Break the SQLCipher-at-rest invariant
- Leak the operator's wallet seed or API keys via process listing, log files, or env exfiltration
- Forge an attestation report or signature claim
- The operator hosting your instance can be subpoenaed. Phantom's design minimises what they CAN disclose; it does not make the operator immune.
- Physical seizure of an unlocked VPS exposes the live SQLCipher decrypted memory image. Mitigation is operational (do not unlock unless serving).
- Supply-chain attacks on
requirements.lock. Phantom installs with--require-hashes, but cannot detect malicious crates introduced before the lockfile was generated. - Vendor-side logging for
PROXYtier models. Customers pay anonymously, but OpenAI/Anthropic/Google still read the content. Phantom only hides identity, not content. This is documented infrontend/terms.html#privacy.
HANDOFF.md carries the full design rationale and threat model. Skim that before reporting; many "vulnerabilities" are documented trade-offs.
Best-effort acknowledgment within 5 business days. Coordinated disclosure window: 90 days from first contact unless an active exploit warrants faster.
