# Security Policy

## Supported versions

Anansi is pre-1.0 (`0.1.x`). Security fixes ship on `main` and are noted in release notes. There is no LTS branch yet.

## Reporting a vulnerability

Do **not** open a public issue for suspected vulnerabilities.

Report privately via [GitHub Security Advisories](https://github.com/jojomensah89/anansi/security/advisories/new) (preferred). Include:

- affected component (extension / web server / MCP / CLI / db)
- steps to reproduce or proof-of-concept
- impact (what an attacker can read / write)
- your environment (Bun version, browser, commit SHA)

We will acknowledge within 72 hours, keep you updated on a fix, and credit you on release unless you prefer anonymity.

## Scope notes

Anansi is intentionally conservative about browser access:

- No `<all_urls>` permission, no `cookies` permission.
- No GitHub OAuth or personal access token for extension capture.
- Library, extension and MCP access fail closed without credentials. Explicit
  `LIBRARY_TOKEN`, `INGEST_TOKEN` and `MCP_TOKEN` override `ANANSI_SECRET` for
  their respective roles; otherwise the master secret is the fallback.
- The local database and media live under `data/` and must never be committed.

Please do not submit reports asking for session-cookie exfiltration, token harvesting, or bypassing platform login — those are out of scope by design.

## Secrets hygiene

Never put `ANANSI_SECRET`, `INGEST_TOKEN`, `MCP_TOKEN`, or `LIBRARY_TOKEN` in
`VITE_*` vars, committed files, screenshots, or issue logs. Rotate any secret
that was ever pasted publicly. Use a separate ingest key for the extension to
limit its authority. Rotation requires reconnecting affected clients.

Default Chrome builds are public artifacts with no embedded deployment URL or
credential. Connect them through the popup. Explicit private build mode can embed
`ANANSI_EXTENSION_INGEST_TOKEN`; anyone with that artifact can extract it.
Never publish or share a private configured build. Rebuild after rotating its key.

## Request protection

The Worker uses separate Cloudflare rate-limit bindings for login, extension
requests and MCP. Counters are per Cloudflare location and eventually consistent,
not global quotas. Shared IP addresses share a budget. Missing or failing bindings
close those routes with 503; throttling returns 429 and a retry hint. Confirm the
bindings and any additional WAF rules on the deployed Worker before launch.

Capture relays run on provider pages. Same-page scripts are not trusted simply
because they know the relay nonce: it correlates messages, not authenticates a
provider. Source identity, bounded payloads and queue limits remain required.
See PRIVACY.md for capture destinations and optional AI processing.
