Key findings
- high· other —The iframe receives messages from any origin without verification, then performs a GET request to the provided URL and returns the response blob. This allows arbitrary websites to use the extension as a cross-origin proxy, potentially exfiltrating data or bypassing CORS restrictions.
The extension communicates only with and associated domains for its stated PDF processing functionality, using minimal permissions. Analytics and authentication are first-party and expected. No malicious code patterns were found. However, a security vulnerability exists in where the message listener lacks origin validation, allowing any website to proxy requests through the extension. This is a design flaw but not indicative of malicious intent.
