#23096: feat(secrets): add Bitwarden/Vaultwarden secret provider

## Summary - **Problem:** OpenClaw has no Bitwarden/Vaultwarden integration for secret management. Users who rely on Bitwarden (55M+ users) cannot store API keys and tokens in their vault. - **Why it matters:** Issues #58 and #24875 request this. Bitwarden is the most popular open-source password manager and is self-hostable via Vaultwarden — a natural fit for OpenClaw's self-hosted audience. - **What changed:** Added `BitwardenSecretProvider` implementing the `SecretProvider` interface from PR #16663, with 34 unit tests. Supports `${bw:item-name/field-name}` syntax. - **What did NOT change:** No changes to existing code. This PR adds two new files only. ## Change Type (select all) - [x] Feature - [x] Security hardening ## Scope (select all touched areas) - [x] Auth / tokens - [x] Memory / storage ## Linked Issue/PR - Closes #58 - Closes #24875 - Depends on #16663 (SecretsProvider interface — must land first) - Related #17311 (env/keyring/1Password providers) - Related #7916 (encrypted API keys / secrets management) ## User-visible / Behavior Changes New secret reference syntax for Bitwarden: ```json5 { "secrets": { "providers": { "bw": { "serverUrl": "https://vaultwarden.example.com", "collectionId": "openclaw-secrets" } } }, "models": { "providers": { "anthropic": { "apiKey": "${bw:anthropic-key/password}" } } } } ``` Field extraction supports: `password` (default), `username`, `notes`, `uri`, `totp`, and custom fields by name. ## Security Impact (required) - New permissions/capabilities? `No` - Secrets/tokens handling changed? `Yes` — adds a new secrets provider that reads from Bitwarden CLI - New/changed network calls? `No` — delegates to `bw` CLI which handles all network communication - Command/tool execution surface changed? `Yes` — spawns `bw` CLI via `execFile` (no shell) - Data access scope changed? `No` - Risk + mitigation: - `bw` CLI is invoked via `execFile` (not `exec`) — no shell injection possible - BW_SESSION and other credentials are passed via env to the child process, never written to disk or logged - `--nointeraction` and `--raw` flags prevent interactive prompts and ensure clean output parsing - All errors are mapped to `BitwardenCliError` with actionable hints, never exposing raw vault data ## Repro + Verification ### Environment - OS: macOS (tested), Linux/Windows (mocked) - Runtime: Node.js 22+ - Requires: Bitwarden CLI (`bw`) installed and logged in ### Steps 1. Install Bitwarden CLI: `brew install bitwarden-cli` or `npm install -g @bitwarden/cli` 2. Log in: `bw login` then `export BW_SESSION=$(bw unlock --raw)` 3. Create a test item: `bw get template item | jq '.name="test-key" | .login.password="sk-test-123"' | bw encode | bw create item` 4. Configure OpenClaw: add `${bw:test-key/password}` as an API key reference 5. Verify resolution ### Expected - Secret resolves to `sk-test-123` - Cache prevents repeated CLI calls within TTL ### Actual - Works as described (verified via unit tests) ## Evidence - [x] 34 unit tests, all passing - [x] 0 lint errors (oxlint) - [x] 0 format issues (oxfmt) - [x] Tests cover: getSecret (14 tests), setSecret (3), listSecrets (3), testConnection (4), error handling (4), configuration (6) ## Human Verification (required) - Verified scenarios: All 34 test cases covering field extraction, cache, error mapping, env isolation, auth modes - Edge cases checked: missing fields, null notes/URIs, locked vault, unauthenticated state, multiple item matches, CLI not installed - What I did **not** verify: Live Bitwarden vault (tests use mocked CLI responses). Live verification is possible once PR #16663 lands and the provider can be wired into `buildSecretProviders()`. ## Compatibility / Migration - Backward compatible? `Yes` — entirely opt-in, no existing behavior changes - Config/env changes? `Yes` — new `secrets.providers.bw` config section (only used if configured) - Migration needed? `No` ## Failure Recovery (if this breaks) - How to disable/revert: Remove `bw` from `secrets.providers` config, or revert to plain-text API keys - Files/config to restore: `openclaw.json` (remove `secrets.providers.bw` section) - Known bad symptoms: `BitwardenCliError` with actionable hint messages for every failure mode ## Risks and Mitigations - Risk: PR #16663 may not land or the `SecretProvider` interface may change - Mitigation: This PR depends on #16663 and documents the dependency clearly in code. If the interface changes, this provider will be updated to match. - Risk: `bw` CLI output format may change across versions - Mitigation: Tests mock CLI output based on current documented format. The JSON structure is stable and documented by Bitwarden. ## AI-Assisted - [x] This PR was AI-assisted (Claude) - [x] Fully tested (34 unit tests) - [x] I understand what the code does - [x] Verified against official Bitwarden CLI documentation (https://bitwarden.com/help/cli/) Made with [Cursor](https://cursor.com) <!-- greptile_comment --> <h3>Greptile Summary</h3> Adds a Bitwarden/Vaultwarden secret provider (`BitwardenSecretProvider`) that implements the `SecretProvider` interface from PR #16663, enabling `${bw:item-name/field-name}` secret references. The provider uses `execFile` (no shell) for CLI invocation, isolates credentials via child process env overrides, and includes comprehensive error mapping with actionable hints. - **TOTP caching bug**: TOTP codes (which rotate every ~30 seconds) are cached with the general TTL (default 5 minutes), meaning stale/invalid codes will be returned after the first 30 seconds — causing silent authentication failures. - **`setSecret` notes duplication**: When creating a new item with `field === "notes"`, the value is stored in both the `notes` property and as a custom field named `"notes"` due to an incomplete exclusion in the ternary condition on the `fields` array. - **`setSecret` error swallowing**: The bare `catch` block when checking for existing items treats all errors (vault locked, CLI missing, network errors) as "item not found," masking the real error and attempting an item creation that will fail with a confusing secondary error. - Good security practices: `execFile` over `exec`, env isolation without mutating `process.env`, `--nointeraction` and `--raw` flags. - Thorough test suite with 34 tests, though missing coverage for the notes-on-create and TOTP caching edge cases. <h3>Confidence Score: 3/5</h3> - This PR has logic bugs that should be fixed before merging, but they won't break existing functionality since this is an additive, opt-in feature. - Score of 3 reflects two confirmed logic bugs (TOTP caching returning stale codes, notes field duplication on create) and one error-handling issue (bare catch swallowing CLI errors in setSecret). None of these affect existing code since this is a new, opt-in provider, but they will cause incorrect behavior for users who adopt it. The security model is sound (execFile, env isolation, no shell injection surface). - Pay close attention to `src/config/bitwarden-secret-provider.ts` — specifically the `getSecret` TOTP caching path (line 221-225) and the `setSecret` create-new-item branch (lines 238-269). _{Last reviewed commit: 35578de} <!-- greptile_other_comments_section --> _{(2/5) Greptile learns from your feedback when you react with thumbs up/down!} <!-- /greptile_comment -->
