| शीर्षक | jae-jae fetcher-mcp 0.3.9 non-blind SSRF |
|---|
| विवरण | fetcher-mcp has a non-blind SSRF vulnerability in its fetch_url and fetch_urls tools. The only URL validation is validateUrlProtocol(), which checks that the scheme is http: or https:. It does not reject loopback, private, link-local, reserved, or cloud metadata addresses before page.goto(url). The validated URL is then passed to Playwright navigation through page.goto(url), and the fetched page content can be returned to the MCP caller. |
