docs(security): correct false desktop encryption claims - #352

Conversation
docs/IDB-ENCRYPTION.md claimed Tauri desktop shares the web build's full
IDB encryption lifecycle. It doesn't: services/fs/*Store.ts writes project,
settings, snapshot, Codex, RAG, and binder-asset data as plaintext
(LZ-string compressed only) regardless of the enableIdbAtRestEncryption
setting. Enabling it on desktop still shows the passphrase unlock screen,
which currently gates nothing on the filesystem side.
Separately, the desktop API-key encryption "fix" credited to F-05/F-06
(2026-07-29, AUDIT.md/CHANGELOG.md) upgraded the KDF (unsalted SHA-256 ->
PBKDF2 + random salt) but never addressed the actual finding: the PBKDF2
passphrase input (`${appDataPath}|${provider}|WorldScriptStudio|v1`) is
built entirely from public/discoverable values, so anyone with read access
to the encrypted key file can reconstruct it and decrypt in one step. No
brute force needed - the added iterations defend against an attack that
isn't the real one. AUDIT.md, CHANGELOG.md, and SECURITY-THREAT-MODEL.md
all still described this as resolved.
Corrects all four docs to state the real, current status and reopens
F-05/F-06 in AUDIT.md. Real fixes for both gaps are tracked as follow-up
work (fold API keys and project data into the existing user-passphrase
protected-store scheme in services/storage/encryptionMigrationOrchestrator.ts
instead of the current derived-passphrase/plaintext state).
Docs-only change, no code/behavior modified.

Hey - I've left some high level feedback:
- The docs now hardcode the PBKDF2 input string as
${appDataPath}\|${provider}\|WorldScriptStudio\|v1; consider cross-checking this delimiter and version literal against the actual implementation (and clarifying the escaping in Markdown) so future refactors don't silently desync the threat description from the code.

… desktop key split Review-loop follow-up on PR #352: - docs/SECURITY-THREAT-MODEL.md's attack tree and header still called F-05/F-06 "fixed" despite the corrected Mitigation Mapping row above it saying "not resolved" — reconciled to be internally consistent. - Documented that components/ApiKeySection.tsx never adopted the storageService/FsSettingsStore path: it saves the Gemini key via dbService (IndexedDB) even on desktop, while geminiService.ts reads it via storageService (filesystem on desktop) — so a Gemini key saved through Settings on desktop is invisible to the code that uses it.

…a row to threat model Third review-loop wave on PR #352: - Tightened attacker-capability wording in both the Mitigation Mapping row and the attack tree: recovering the key needs the ciphertext AND the public derivation inputs, not the ciphertext alone. - Added the Gemini-exception note (already in README.md/ IDB-ENCRYPTION.md) to the threat model's own API-key row and attack tree, so all three documents agree. - Added a new Mitigation Mapping row for desktop project/settings/ snapshot/Codex/RAG/image data — the authoritative threat model previously didn't mention this exposure at all, so a reader could conclude manuscript disclosure/tampering was mitigated on desktop when it wasn't. Points at PR #356 for the real fix. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

| | API key leakage via logs | StructuredLogger sanitization; never log keys | `services/logger.ts:sanitizeLogContext()` | | ||
| | Desktop API key exposure via local file-read access | AES-256-GCM with a PBKDF2-derived key (600 000 iterations, SHA-256, random 32-byte salt per encryption) — fixed 2026-07-29; the prior scheme derived the key from a single unsalted SHA-256 digest of publicly-derivable material (own file's parent path + provider name from the filename + a hardcoded literal), so anyone with read access to `config/<provider>_key.enc.json` could reconstruct the key in one hash operation (F-05/F-06). No migration path for pre-fix files by design — a legacy (unsalted) payload is discarded and the user is prompted to re-enter the key. | `services/fs/fsCore.ts:deriveFileSystemCryptoKey()`, `services/fs/settingsFsStore.ts:getApiKey()` | | ||
| | Desktop API key exposure via local file-read access _(does not apply to Gemini — see note below)_ | **Not resolved — corrected 2026-08-13.** The 2026-07-29 change (F-05/F-06) replaced a single unsalted SHA-256 digest with PBKDF2 (600 000 iterations, SHA-256, random 32-byte salt), which stops rainbow-table and multi-target reuse attacks — but the derivation *input* passed to PBKDF2 is still `${appDataPath}\|${provider}\|WorldScriptStudio\|v1`, built entirely from a standard OS app-data path, a public provider-name enum, and hardcoded literals. An attacker with the ciphertext (`config/<provider>_key.enc.json` — the exact threat this row exists to cover) and those public/reconstructible derivation inputs can derive the key in one PBKDF2 call and decrypt the file; no brute force or precomputed table is needed, so the added iteration count provides no real defense here. The underlying "obfuscation, not encryption" finding was never actually closed. Real fix tracked: fold API keys into the same user-passphrase-protected store scheme `storageEncryptionService.ts`/`encryptionMigrationOrchestrator.ts` already provide, keyed by an actual user secret instead of a derived public string; honest plaintext fallback when no passphrase is set. **Gemini exception:** `components/ApiKeySection.tsx` never adopted this filesystem path at all — it reads/writes the Gemini key through `dbService` (browser IndexedDB) even on desktop, while `services/geminiService.ts` reads it through `storageService` (filesystem on desktop); this row's file-read analysis doesn't apply to Gemini, whose actual failure mode is a functional split-persistence bug (a key saved on desktop is invisible to the code that uses it), tracked in [#358](https://github.com/qnbs/WorldScript-Studio/issues/358). | `services/fs/fsCore.ts:deriveFileSystemCryptoKey()`, `services/fs/settingsFsStore.ts:getApiKey()` | | ||
| | Desktop project/settings/snapshot/Codex/RAG/image data exposure and tampering via local file-read access | **Not resolved as of 2026-08-13.** `services/fs/*Store.ts` writes this data as plaintext (LZ-string compressed only) regardless of the `enableIdbAtRestEncryption` setting — there is neither confidentiality (no encryption) nor authentication (no AEAD tag, so silent tampering is possible) for any of it on disk today, unlike the IndexedDB manuscript rows above. Enabling "Encrypt project data at rest" in Settings → Privacy shows the same unlock screen as the browser/PWA build but does not protect these files. Real fix in progress: [PR #356](https://github.com/qnbs/WorldScript-Studio/pull/356) reuses `storageEncryptionService.ts`'s real passphrase-derived key for this filesystem path; update this row to "Resolved" once that PR merges and is verified. | `services/fs/*Store.ts` | |
There was a problem hiding this comment.
For an attacker with only the stated local file-read access, disclosure is possible but tampering is not; modifying these files requires write access. Fresh evidence in this revision is that the new combined row records desktop tampering only under Information Disclosure, while the formal Tampering section still universally claims that manuscript modification is mitigated by AES-GCM (line 23), even though Tauri selects the plaintext filesystem backend. Split this into a read/disclosure threat and a write/tampering threat, and qualify the existing AES-GCM row as IndexedDB-only.

| Tauri uses the same WebView storage encryption lifecycle as the web build. The repository does **not** currently use `tauri-plugin-stronghold`, an OS keychain, or a transparent desktop-only passphrase store. Desktop users enter the passphrase through the same unlock flow and receive the same locked-write guarantees. | ||
| **This section previously claimed desktop shares the full encryption lifecycle described above. That was inaccurate — corrected below.** | ||
|
|
||
| On the Tauri desktop build, primary project, settings, snapshot, image, Codex, RAG, and binder-asset data is persisted by the filesystem-backed store (`services/fs/*Store.ts`), not IndexedDB. That store writes plaintext (LZ-string compressed only, no encryption) regardless of `enableIdbAtRestEncryption` — every writer is explicitly commented `ENCRYPTION: plaintext`. Enabling the setting on desktop still shows `IdbUnlockModal`/`PassphraseModal` (the passphrase sentinel lives in the WebView's own IndexedDB, which persists on desktop too), but that unlock flow gates nothing on the filesystem side today — only the UI, not the actual manuscript files under `$APPDATA`, is shared with the web build. See `README.md`'s "Encryption — which mechanism protects what" table for the authoritative per-mechanism breakdown. Extending real at-rest protection to the desktop filesystem store is a tracked, open gap — not yet implemented. |
There was a problem hiding this comment.
When a Tauri user uploads a character or world image, the upload thunks save it through storageService, which selects FsAssetStore, but both CharacterView.useStoredImage() and WorldView.useStoredImage() read it directly through dbService.getImage() from the WebView's IndexedDB. The new text therefore misclassifies images as a working filesystem-backed path whose only gap is encryption; in practice newly saved desktop images are written to a location these views never read. Document this split-persistence exception and track it like Gemini, or route those reads through storageService.

| The one thing that *is* desktop-specific and already encrypted is per-provider API keys (`services/fs/settingsFsStore.ts`, via `encryptText`/`decryptText` in `services/fs/fsCore.ts`) — but that mechanism has its own, separate weakness: its PBKDF2 passphrase is derived from a string built entirely out of public/discoverable values (the app-data path, the provider name, and hardcoded constants), not a real secret. Anyone with filesystem read access to the encrypted key file — the exact threat model at-rest encryption exists to defend against — can reconstruct the same derivation and decrypt it. This is also a tracked, open gap, independent from the project-data gap above; do not treat the presence of `encryptText`/`decryptText` as evidence that desktop API keys are meaningfully protected today. **"Per-provider" excludes Gemini**: `components/ApiKeySection.tsx` never adopted the `storageService`/`FsSettingsStore` path at all — it still reads/writes the Gemini key directly through `dbService` (the browser IndexedDB store), even when running on desktop. `services/geminiService.ts` reads the key through `storageService`, which resolves to the filesystem backend on desktop — so a Gemini key saved via Settings → AI on desktop is written to a location `geminiService.ts` never looks in. This is a functional bug, not a security one; tracked in [#358](https://github.com/qnbs/WorldScript-Studio/issues/358), independent of the two gaps above. | ||

This correction is not reflected in the Help content users actually see: locales/en/help.json:74—mirrored across the generated locale bundles—still lists “Stronghold (optional)” as a desktop capability and says it can store the passphrase so the unlock modal never appears. A repository-wide search found no Stronghold dependency or configuration, so desktop users opening Help still receive the exact false protection claim this section removes; update the locale source and regenerated bundles as part of this truth-up.

The user-facing privacy and API-key Help entries remain inconsistent with this corrected table: locales/en/help.json:68 and locales/en/help.json:76 still tell users that every API key is PBKDF2-encrypted before being stored in IndexedDB and that plaintext is never written to disk. On Tauri, non-Gemini keys instead use the reconstructible filesystem scheme documented here, while Gemini follows the split IndexedDB/filesystem path; moreover, browser idbKeyStore.ts uses a generated random key rather than PBKDF2. Update the locale sources and regenerated bundles so the application's own security guidance does not retain these false guarantees.

Suggestion: The asynchronous onloadend callback does not catch failures from storageService.saveImage or call reject. If the selected storage backend cannot write the image, this callback's rejected promise is detached from the outer promise, leaving the thunk pending indefinitely and preventing the upload failure state from being produced. Wrap the save in try/catch and reject the outer promise on failure. [api mismatch]
Severity Level: Major ⚠️
- ❌ Character upload requests can remain pending forever.
- ⚠️ Upload failure feedback and completion state become unavailable.

Suggestion: The asynchronous onloadend callback does not catch failures from storageService.saveImage or call reject. A filesystem or IndexedDB write failure therefore produces an unhandled rejection while the outer promise returned to createAsyncThunk remains pending, so callers can wait forever. Propagate the save error through the outer promise. [api mismatch]

When a user selects any non-English UI language, these corrected Help entries are replaced by that locale's own stale values: all 18 non-English locales/*/help.json sources still retain at least one disproven guarantee, and their corresponding runtime bundles remain unchanged. For example, locales/de/help.json:74 still advertises the nonexistent Stronghold integration, while lines 76 and 80 still claim every API key is PBKDF2-encrypted in IndexedDB and plaintext is never written to disk. Update the localized sources and regenerate every public/locales/*/bundle.json; otherwise desktop users outside English continue receiving the security claims this change is intended to retract.

When a web/PWA user invokes Claude on a Vercel or Cloudflare Pages deployment, this statement is false: services/aiProviderService.ts:411-416 sends the Anthropic key in the JSON body to /api/claude-proxy, and api/_shared/claudeProxyCore.ts:151-158 reads it and forwards it upstream. The revised Help entry should describe this serverless-relay exception, matching the disclosure already present in README.md:343-350, rather than assuring users that no API key is ever transmitted to WorldScript infrastructure.

| Tauri uses the same WebView storage encryption lifecycle as the web build. The repository does **not** currently use `tauri-plugin-stronghold`, an OS keychain, or a transparent desktop-only passphrase store. Desktop users enter the passphrase through the same unlock flow and receive the same locked-write guarantees. | ||
| **This section previously claimed desktop shares the full encryption lifecycle described above. That was inaccurate — corrected below.** | ||
|
|
||
| On the Tauri desktop build, primary project, settings, snapshot, image, Codex, RAG, and binder-asset data is persisted by the filesystem-backed store (`services/fs/*Store.ts`), not IndexedDB. That store writes plaintext (LZ-string compressed only, no encryption) regardless of `enableIdbAtRestEncryption`. Enabling the setting on desktop still shows `IdbUnlockModal`/`PassphraseModal` (the passphrase sentinel lives in the WebView's own IndexedDB, which persists on desktop too), but that unlock flow gates nothing on the filesystem side today — only the UI, not the actual manuscript files under `$APPDATA`, is shared with the web build. Character and world image reads use `storageService`, so they now follow the same selected backend as image uploads; this removes the prior desktop filesystem/IndexedDB split-persistence availability bug. See `README.md`'s "Encryption — which mechanism protects what" table for the authoritative per-mechanism breakdown. Extending real at-rest protection to the desktop filesystem store is a tracked, open gap — not yet implemented. |

When a Tauri user opens Help → Advanced → At-Rest Encryption, locales/en/help.json:6—registered by services/help/helpCatalog.ts:298-299—still says primary project data, snapshots, and settings are AES-256-GCM protected and that reads and writes fail closed while locked. That directly contradicts this corrected desktop section, because those filesystem records remain plaintext and the unlock flow gates none of them; the same Help article also says changing or disabling encryption is unavailable even though Phase 4 now exposes both operations. Update this user-facing article and its runtime bundle so English desktop users do not retain a false protection guarantee.

User description
Summary
Two documented "resolved"/"protected" claims about desktop encryption are false against current code. This PR corrects the docs only — no code changed.
docs/IDB-ENCRYPTION.mdclaimed Tauri desktop shares the web build's full IDB encryption lifecycle. It doesn't:services/fs/*Store.tswrites project, settings, snapshot, Codex, RAG, and binder-asset data as plaintext (LZ-string compressed only) regardless of theenableIdbAtRestEncryptionsetting. Enabling it on desktop still shows the passphrase unlock screen, which currently gates nothing on the filesystem side — giving desktop users a false sense of protection.AUDIT.md,CHANGELOG.md,docs/SECURITY-THREAT-MODEL.md) were marked resolved on 2026-07-29 for upgrading desktop API-key encryption from unsalted SHA-256 to PBKDF2 + random salt. That upgrade hardens against rainbow-table/multi-target reuse, but never addressed the actual finding: the PBKDF2 passphrase input —`${appDataPath}|${provider}|WorldScriptStudio|v1`— is built entirely from public/discoverable values (standard OS app-data path, public provider enum, hardcoded literals). Anyone with read access to the encrypted<provider>_key.enc.jsonfile can reconstruct the identical string and decrypt in one PBKDF2 call — no brute force needed, so the extra iterations defend against an attack that isn't the real one.Changes
docs/IDB-ENCRYPTION.md— rewrote "Tauri Desktop Layer" section with the accurate current state for both gaps.docs/SECURITY-THREAT-MODEL.md— corrected the "fixed 2026-07-29" framing on the desktop API-key row.AUDIT.md— reopened F-05/F-06 with an "Incomplete" note explaining what the 2026-07-29 fix did and didn't address.CHANGELOG.md— appended a correction note to the historical F-05/F-06 entry (kept the original text — it accurately describes what code changed — rather than rewriting history).README.md— "Encryption — which mechanism protects what" table: fixed the misleading "Install-scoped secret material" phrasing for the desktop API-key row, added a missing row for desktop project data (previously absent from the table entirely), marked bothFollow-up (tracked, not in this PR)
Real fixes for both gaps: fold API keys and project/settings/snapshot/Codex/RAG/asset data into the existing user-passphrase-protected-store scheme (
services/storage/encryptionMigrationOrchestrator.ts) instead of the current derived-passphrase (API keys) / plaintext (project data) state, with an honest plaintext fallback when no passphrase is set. Landing as separate PRs since they touch real code paths and need their own test coverage (round-trip, wrong-passphrase, corrupted-envelope, interrupted-migration-resume).Test plan
