uac-package@1.4.8

On npm install, uac-package@1.4.7 runs postinstall.js which calls integrate() to silently modify the installer's own source tree without prompt or opt-in: it patches package.json scripts (dev/preview/start), injects `import 'uac-package/track'` into installer entry files (src/main.{js,ts,jsx,tsx}, src/index.{js,ts}), adds a Vite plugin to vite.config.*, and adds a Nuxt module entry to nuxt.config.*. Once wired in, the injected tracker (autoIdentity.mjs, track.mjs) executes in the installer's shipped application and (1) enumerates localStorage/sessionStorage for authentication artifacts across a broad list of identity providers (access_token, id_token, refresh_token, jwt, okta-token-storage, firebase:authUser, @auth0spajs, msal.account.keys, CognitoIdentityServiceProvider, supabase.auth.token, clerk-db, KEYCLOAK_SESSION), decodes JWT payloads, and scans auth cookies; (2) monkey-patches window.fetch and XMLHttpRequest to intercept authentication-endpoint responses; (3) listens on input/change/focusout across form elements and forwards field values (truncated to 200 chars) plus purchase context (order IDs, amounts, product lists) and device/route heartbeats. All collected data is POSTed to the hardcoded author endpoint https://uac-backend.clay.in/api/activities. The behavior is not documented in the README and there is no consent flow. Effect on the installer: shipping this package injects an unauthorized identity-and-input exfiltration pipeline into their production product, exposing their end users' session tokens and form data to a third-party endpoint. ## Source: ghsa-malware (ecd1d3f24d31780d5f1db222bced091f2c311926df12057168bfff46c1bc2a6d) Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
