What our analysis found

AI Assistant, used by 1,000 people, is rated caution by Extension Auditor. Our code review reported 2 findings (2 medium), led by code injection. It comes from a publisher with 2 extensions and was last updated in April 2023.

Key findings

  • Medium

    Code Injection

    The modal's `setContent` method passes the raw GPT API response string to jQuery's `.html()`, which parses and renders it as live HTML in the DOM of every page the user visits. Because the response originates from a publisher-controlled AWS Lambda endpoint (`[domain withheld]`), a backend change could silently inject arbitrary HTML or JavaScript into any tab where the modal has been invoked. This risk is materially elevated by the publisher's 100% malicious rate on their other extensions.

  • Medium

    Unauthorized Data Collection

    All user queries, typed prompts, and page URLs (for Page actions) are POSTed to a publisher-controlled AWS Lambda endpoint. The CWS listing explicitly declares no data collection, making this transmission undisclosed. The endpoint has no brand affiliation stated anywhere in the extension or the privacy policy, and is not a known AI SaaS provider (OpenAI, Anthropic, etc.) — it is solely controlled by a publisher with a fully malicious track record on their other extensions.

Analyst notes

The extension's code is readable and functionally consistent with its stated purpose as an AI assistant; there is no obfuscation, credential harvesting, or covert exfiltration. However, two concrete concerns elevate it: (1) the content script renders the GPT API response directly as HTML into every visited page's DOM via jQuery's `.html()` (:44), giving the publisher's backend — a generic AWS Lambda with no disclosed identity — a persistent code-injection vector into all pages, and (2) user queries and page URLs are transmitted to that publisher-controlled endpoint with zero data collection disclosed in the CWS listing. The publisher's 100% malicious rate on their other extensions () significantly amplifies both risks. The ML score (0.54), low rating, and low user count corroborate concern; the clean permission set and use of legitimate ExtPay billing contradict it.
