The extension's permissions (webRequest, declarativeNetRequest, <all_urls>) are directly required to add CORS headers to responses, as stated in its description. The code exclusively uses these APIs to modify response headers based on user configuration; no browsing data is collected or transmitted. The only external network requests are user-initiated page openings () or a one-time welcome page on, which match the publisher's own domain. The explore feature loads a local JSON file to suggest related extensions without any remote data exchange. All settings are stored locally via chrome.storage and session, and no evidence of obfuscation or covert exfiltration exists. The ML model's risk score is low (0.00), and the pre-computed security analysis incorrectly flags required permissions as risks without recognizing the legitimate use case.
