# Phase 14.2.1 — Security Review

> Lean Translate plugin (`sm-translate-plugin`), cabana `markdown`/`mltext`/`mlmarkdown`,
> surf `LocaleResolver`, and the proof-host boot of user+translate. Every
> T-14.2.1 threat locked in plans 01–04 and 06 is mapped below to executed, named Go
> or Vitest evidence. Unmapped IDs would be a review gap, not an accepted
> risk; none exist.

**Date:** 2026-10-06
**Scope:** Plans 14.2.1-01 through 14.2.1-06; `sm-translate-plugin`;
`summercms.go` modules `cabana` and `surf` plus admin SPA ML/markdown
controls; proof host `sm-grzybyfunkcjonalne-app`.
**Repos grepped:** `sm-translate-plugin`, `summercms.go` (excluding
`.planning/` except this review), `sm-grzybyfunkcjonalne-app`.

## Reviewer Note

14.2.1-04-PLAN.md Task 3 calls for an independent `gsd-security-auditor`
agent pass. This Cursor session has no dedicated security-auditor subagent
(same fallback as Phase 08): the 14.2.1-04 executor performed the review
directly, and 14.2.1-06 Task 3 appended CR-01/WR-02 rows the same way. Every
high threat below is closed with source citations and named tests
**re-executed during this review** (2026-10-06), not merely inherited
from earlier plans. The executor checkpoint return states this plainly.

No external API integration: this phase ports a compiled plugin and local
framework/host contracts only.

---

## Verdict Summary

The register contains **24 total threats: 24 closed, 0 open, 0 accepted
risks**. High findings block phase completion; all high rows are mitigate
with executed named tests. PHP pin SHA `725d547ec839f02b5fdc0f0a6faaed601a414d50`
is unchanged.

## Trust Boundaries

| Boundary | Description | Data Crossing |
|----------|-------------|----------------|
| untrusted request → Translator | URL prefix, cookies, Accept-Language, principal preferred_locale | locale codes only; must match enabled Locale rows |
| unauthenticated vs `manage_locales` | Locales admin CRUD | JWT + permission grant |
| admin SPA → cabana save | nested mltext/mlmarkdown JSON | locale→string maps lifted before Fill |
| markdown source → HTML | stored body / SPA preview | goldmark without WithUnsafe; SPA interpolates text |
| test fixture → production binary | process-local `acme.fixture` | must not appear in generated plugin imports |
| gate → production claims | skipped containers / stale dist | named PASS + final marker |

## Findings by Threat

### T-14.2.1-01 — locale injection

- **Source:** `sm-translate-plugin/classes/translator.go` `isValid` / `enabledCodes` (enabled Locale rows only).
- **Test evidence (re-run 2026-10-06):** `TestTranslatorResolve` subtests `invalid_url_session_and_header_ignored`, `url_prefix_wins_and_strips`, `accept-language_reduced_to_enabled_codes` — PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-02 — process-wide locale leak

- **Source:** `Translator.Locale` reads `towel.Locale(ctx)` only; no package-level current locale.
- **Test evidence (re-run 2026-10-06):** `TestTranslatorConcurrentIsolation` PASS; `TestLocaleResolver` isolation subtest PASS; plugin `go test ./... -race` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-03 — manual cookie as locale

- **Source:** `hasManualFlag` treats any non-empty value as a flag; `rememberedLocale` reads a different cookie name.
- **Test evidence (re-run 2026-10-06):** `TestManualFlagIsNotALocale` (package classes); `TestTranslatorResolve/manual_flag_blocks_accept-language` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-04 — schema / AutoMigrate

- **Source:** gormigrate files `updates/202610060001`–`005`; plugin production Go has no `AutoMigrate`.
- **Test evidence (re-run 2026-10-06):** `TestTranslateTables`, `TestSeedEnPl`, `TestTranslateMigrationsRollbackAndRemigrate` PASS. Gate `--forbidden` refuses production `AutoMigrate`.
- **Disposition:** closed / mitigate.

### T-14.2.1-05 — manage_locales privilege

- **Source:** `controllers/locales.go` `RequiredPermissions` = `golem15.translate.manage_locales`.
- **Test evidence (re-run 2026-10-06):** `TestLocalesAdminForbidden` PASS; `TestTranslateEndToEnd` 403 on list/schema without the grant PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-06 — Locale mass assignment and default lifecycle

- **Source:** `models/locale.go` `Fillable` is `code,name,is_enabled`; `FormBeforeDelete` / `FormBeforeUpdate` / `makeDefault`.
- **Test evidence (re-run 2026-10-06):** `TestLocalesAdminMassAssignment`, `TestLocalesAdminDefaultGuards` covered by the plugin suite (smoke + full admin tests) PASS in `go test ./...`.
- **Disposition:** closed / mitigate.

### T-14.2.1-07 — undeclared field / invalid locale writes

- **Source:** `classes/translatable.go` `validateCall`.
- **Test evidence (re-run 2026-10-06):** `TestInvalidLocaleRejected`, `TestTranslatableGetSet` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-08 — morph/index isolation

- **Source:** `WhereIndex` predicates on `model_type`, `locale`, `item`, `value`.
- **Test evidence (re-run 2026-10-06):** `TestTranslatableIndexAndMorphIsolation` in the plugin `./...` suite PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-09 — nested ML JSON

- **Source:** `modules/cabana/field_ml.go` `liftMLValues` (enabled locale codes, string values, default required).
- **Test evidence (re-run 2026-10-06):** `TestMLFieldTypes`, `TestMLNestedSave` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-10 — TranslationWriter privilege

- **Source:** `cabana.TranslationWriter` comment and `crud.go` `save`: apply after Create/Update, after permission/query/lock checks.
- **Test evidence (re-run 2026-10-06):** `TestML/writer_is_not_invoked_before_query_checks`, `TestML/writer_failure_rolls_back_host_write` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-11 — ML mass assignment

- **Source:** lift before `ProjectWritableFields`; extra nested keys stay blocked.
- **Test evidence (re-run 2026-10-06):** `TestMLNestedSave` PASS (unlifted nested maps empty; extra locale `de` rejected).
- **Disposition:** closed / mitigate.

### T-14.2.1-12 — stored XSS / markdown

- **Source:** `RenderMarkdown` goldmark without `html.WithUnsafe`; rejects script/iframe/event/javascript/vbscript/data. SPA preview interpolates text, no `v-html=`.
- **Test evidence (re-run 2026-10-06):** `TestMarkdownRejectsUnsafeHTML` (script/iframe/event/javascript/vbscript/data) PASS; Vitest `tests/form/MarkdownField.test.ts` 3/3 PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-13 — submodule provenance

- **Source:** host gitlinks `plugins/golem15/{user,translate}`.
- **Test evidence (re-run 2026-10-06):** `TestBootUserTranslate` PASS; `--layout` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-14 — gate repudiation

- **Source:** `scripts/check-phase14.2.1.sh` JSON detector.
- **Test evidence (re-run 2026-10-06):** `--self-test` PASS (fail/skip/zero/no-tests/race/missing-named).
- **Disposition:** closed / mitigate.

### T-14.2.1-15 — concurrent Translator

- **Source:** context-only locale; Rewrite clones the request.
- **Test evidence (re-run 2026-10-06):** `TestTranslatorConcurrentIsolation` PASS; plugin `-race` PASS; `TestLocaleResolver/conflicting_requests_stay_isolated` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-16 — migration rollback

- **Source:** gormigrate RollbackLast ×5 then remigrate on a dedicated database.
- **Test evidence (re-run 2026-10-06):** `TestTranslateMigrationsRollbackAndRemigrate` PASS.
- **Disposition:** closed / mitigate.

### T-14.2.1-17 — generated artifacts

- **Source:** committed `admin/openapi/admin.json`, `schema.d.ts`, `modules/boardwalk/dist`.
- **Test evidence:** `TestMLOpenAPIConformance` PASS (re-run 2026-10-06); gate `--admin` regenerates and diffs.
- **Disposition:** closed / mitigate.

### T-14.2.1-18 — test fixture in production

- **Source:** `party.Register` of `acme.fixture` is `sync.Once` inside tests only.
- **Test evidence (re-run 2026-10-06):** `TestTranslateEndToEndFixtureAbsentFromProduction` matched by `TestTranslateEndToEnd*` in the plugin `./...` run PASS; host `plugins.gen.go` lists only `golem15.user` and `golem15.translate`.
- **Disposition:** closed / mitigate.

### T-14.2.1-19 — ML hydration disclosure

- **Source:** `modules/cabana/field_ml.go` `hydrateMLRecord` walks declared `mltext`/`mlmarkdown` fields only; list projection never calls it; `TranslatedExact` skips D-11 so missing pl stays empty. ShowChild uses the same helper after `loadParent`/`loadChild`.
- **Test evidence (re-run 2026-10-06):** `TestMLHydration` PASS (english-only pl is `""`); `TestRelationChildMLNestedSave` PASS (create/update/show hydrated maps).
- **Disposition:** closed / mitigate.

### T-14.2.1-20 — enabled locale list on schemas

- **Source:** `modules/cabana/http.go` `enabledContentLocales` after Lookup, copied onto protect()'d form and relation schema meta; `FormMeta.EnabledLocales` is `json:"enabledLocales,omitempty"` so list Meta omits it.
- **Test evidence (re-run 2026-10-06):** `admin/tests/form/formState.test.ts` `seeds every enabled locale as an empty string`; `admin/tests/form/MLFields.test.ts` create-empty selectors list en+pl.
- **Disposition:** closed / mitigate.

### T-14.2.1-21 — adopt merge of GET scalars

- **Source:** `admin/src/components/form/formState.ts` `mergeMLValue` overlays a host string onto the seed for ML fields only; password fields still clear.
- **Test evidence (re-run 2026-10-06):** `admin/tests/form/formState.test.ts` `merges a GET host string onto the seed without dropping sibling locales`; `admin/tests/form/MLFields.test.ts` GET-string cases for mltext and mlmarkdown.
- **Disposition:** closed / mitigate.

### T-14.2.1-22 — relation-child nested ML tampering

- **Source:** `modules/cabana/relation_child.go` `CreateChild`/`UpdateChild` call `liftMLValues` on the child form before `fillChild`/`projectOperation`; undeclared locale, non-string, missing default, and nil writer with a nested map are 422 before Fill.
- **Test evidence (re-run 2026-10-06):** `TestRelationChildMLNestedSave` PASS (create+update persist en/pl; locale `de` is 422 and inserts no row).
- **Disposition:** closed / mitigate.

### T-14.2.1-23 — RelationService writer privilege

- **Source:** `modules/cabana/http.go` `relations()` Lookup of `TranslationWriter` matches `crud()`; no new HTTP route; `applyMLTranslations` runs after `loadParent`/`loadChild` and after the child row has a primary key.
- **Test evidence (re-run 2026-10-06):** `TestRelationChildMLNestedSave` PASS; `recordingWriter.WriteTranslated` refuses a zero PK.
- **Disposition:** closed / mitigate.

### T-14.2.1-SC — package installs

- **Source:** no new module versions beyond existing stack pins; plugin `replace` of `sm-user-plugin` points at the host submodule checkout; `gocloud.dev v0.46.0` is the already-decided blob pin. Framework `go.mod` / `admin/package-lock.json` were not changed in this phase.
- **Test evidence:** `git log -- go.mod go.sum` on the framework shows no 14.2.1 commits; plugin go.mod Task 1 added a local replace, not a downloaded package.
- **Disposition:** closed / mitigate.

## Deferred surfaces confirmed absent

Gate `--forbidden` (re-run 2026-10-06, PASS) refuses production `manage_messages`, `plugin.Open`/`yaegi`, plugin `AutoMigrate`, `acme.fixture` outside tests, Winter/RainLab table names in production Go, consuming-application names in framework docs, and `v-html=` in `admin/src`.
