| Título | cyberchitta scrapling-fetch-mcp <= 0.2.2 Fixed in 0.2.3 Improper URL Scheme Validation |
|---|
| Descrição | scrapling-fetch-mcp before version 0.2.3 allows arbitrary local file disclosure through the s_fetch_page and s_fetch_pattern MCP tools. Both tools accept a user-controlled URL and pass it to the underlying fetcher without restricting the URL scheme.
Because the underlying fetcher supports file:// URLs, an attacker able to invoke either MCP tool can read arbitrary files accessible to the server process by supplying a file:// URL. The contents of the local file are returned to the caller as fetched page content.
The vulnerability may be exploited by a malicious MCP client or through prompt injection against an MCP-enabled agent. Version 0.2.3 fixes the issue by restricting accepted URL schemes to http and https before invoking the fetcher. |
