Item
Type
Severity
Description
tabCapture
Permission
High
This permission captures content and audio from browser tabs. Rated High because it can record sensitive web content, capture form input, and monitor user interactions.
offscreen
Permission
High
This permission creates hidden browser documents with full DOM access. Rated High because it can run background operations invisibly, potentially executing malicious code without user awareness.
tabs
Permission
Medium
This permission enables tab management and monitoring. Rated Medium because it can track open tabs, access tab metadata, and monitor user browsing patterns.
storage
Permission
Medium
This permission allows storing data locally in the browser. Rated Medium because it can persist sensitive user data, track user activities over time, and potentially store malicious payloads.

The bundled manifest declares four permissions (tabCapture, tabs, storage, offscreen), but the CWS-published manifest summary shows only two (tabCapture, storage). The `tabs` and `offscreen` permissions are entirely absent from the live store listing, meaning users and enterprise reviewers evaluating the extension's scope from the store page do not see the full declared permissions. Per review policy, any mismatch in permissions between the bundled and published manifests is itself a required finding.

manifest.json (Line 32)
{  "permissions": [    "tabCapture",    "tabs",    "storage",    "offscreen"  ]}

On every install AND every subsequent update the extension opens https://addonup.com in a new active foreground tab without any user interaction. This domain is a third-party affiliate/monetization site with no relation to the publisher's own cusmize.com domain. Because the trigger fires on `UPDATE` as well as `INSTALL`, users are subjected to this unsolicited redirect each time the extension auto-updates, not merely on first install — a pattern common to low-quality monetized extensions from publishers whose other extensions are flagged as malicious.

background.js (Line 396)
chrome.runtime.onInstalled.addListener(async e => {  (e.reason === chrome.runtime.OnInstalledReason.INSTALL || e.reason === chrome.runtime.OnInstalledReason    .UPDATE) && (await (async () => {    try {      chrome.storage.local.set(o)    } catch (e) {      console.error("Error initializing config:", e)    }  })(), chrome.tabs.create({    url: "https://addonup.com",    active: !0  }))})
