OpenSSF/OSV advisory MAL-2026-10138 confirms this npm version as malicious. 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.\*... ## Latest scan - **Scanner version:** external-osv-malicious-v1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 100.0% - **Started:** 2026-07-20T03:55:06.840Z - **Finished:** 2026-07-20T03:55:06.840Z - **Download time:** Not available - **Static scan time:** Not available - **AI review time:** Not available - **Total time:** Not available The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis No additional public attack-surface or AI-review details are available. ## Affected versions and remediation This report applies to uac-package@1.4.8. The same advisory and Firewall decision cover these 9 recorded versions: 1.4.1, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.2.1, 1.3.0, 1.4.0, 1.4.8. - Avoid installing uac-package@1.4.8. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% 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. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** uac-package - **Ecosystem:** npm - **Version:** 1.4.8 - **Version published:** 2026-07-07T11:17:15.166Z - **Package first seen:** 2026-07-02T09:46:06.748Z - **Package last seen:** 2026-07-20T03:55:06.840Z - **Known versions:** 14 - **Latest version:** 1.4.8 - **Appeal under review:** No ## References - [HTML security report]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [ADVISORY]()
