What our analysis found

Indian Railways @etrain.info, used by 100,000 people, is rated caution by Extension Auditor. Our code review reported 3 findings (1 critical, 1 medium, 1 low), led by code injection. It was last updated in November 2025.

Key findings

  • Critical

    Code Injection

    The 'script' message handler executes arbitrary JavaScript code (request.data) provided by the [domain withheld] website in any tab via chrome.tabs.executeScript, without validation or sandboxing. This allows the website to perform unrestricted code injection with the extension's elevated privileges, potentially enabling cookie theft, page manipulation, or data exfiltration on any site.

  • Medium

    Other

    The bundled manifest declares permissions (cookies, tabs, host) that do not match the published manifest summary (Chrome Web Store listing), which shows a manifest v3 with declarativeNetRequestWithHostAccess, offscreen, and no cookies permission. This discrepancy indicates a permissions reduction in a later version, but the current version retains broader access.

  • Low

    Other

    The 'cookies' permission is declared in the manifest but is never used by any code in the extension. This unnecessary permission increases the attack surface and elevates risk without providing any functionality.

Analyst notes

The extension allows the [domain withheld] website to execute arbitrary JavaScript in any tab via an unvalidated 'script' handler (:71-80), posing a critical code injection risk. The bundled manifest declares unnecessary 'cookies' permission and mismatches the published Chrome Web Store manifest (v2 vs v3, different permissions). While the code is not obfuscated and appears to be a companion extension, the unrestricted script execution is a serious vulnerability.
