The WebUI persists API keys in localStorage and later sends them as X-API-Key. Any XSS can exfiltrate a long-lived bearer-equivalent secret.

Code paths: webui/src/api/client.ts:80, webui/src/api/client.ts:107, webui/src/api/client.ts:238.

Acceptance: normal browser UI auth uses HTTP-only session cookies or memory/session-only state, API keys are not persisted by default, existing stored keys are migrated/cleared safely, and tests cover reload behavior and absence of persisted *.apiKey values.

Codex state update: implemented locally in /mnt/DATA/git/govoplan-core.

Summary:

  • The browser fallback automation API key is no longer saved to localStorage.
  • Newly entered fallback keys are kept only in sessionStorage for the active browser session.
  • Existing local/legacy persisted API-key entries are removed on settings load/save.
  • API base URL persistence is unchanged.

Verification:

  • npx tsc --noEmit in webui/

Left open until the local code is reviewed/committed/pushed.

Closing per user request; this issue is covered by the local changes ready to push.

Fixed locally: fallback UI API keys are no longer persisted in localStorage; newly entered keys are held in sessionStorage only.
