Apify Model Context Protocol (MCP) server: Actor MCP path authority injection leaks Apify token

## Actor MCP path authority injection leaks Apify token ### Summary `@apify/actors-mcp-server` version `0.10.7` builds Actor standby URLs by directly concatenating a trusted base URL with an attacker-controlled `webServerMcpPath` value taken from an Actor definition returned by the Apify API. An attacker who publishes a malicious Actor with a crafted `webServerMcpPath` (e.g., `@attacker.example/mcp`) can cause the MCP client to resolve the final URL to an entirely different host. Because the M

Apify Model Context Protocol (MCP) server: Domain Allowlist Bypass in fetch-apify-docs via String Prefix Matching

### Summary The `fetch-apify-docs` tool validates URLs against a domain allowlist using `String.startsWith()` instead of proper URL hostname comparison. This allows bypass via attacker-controlled subdomains (e.g., `https://docs.apify.com.evil.com/`), enabling the tool to fetch and return arbitrary web content to the LLM. ### Details #### Vulnerable component `src/tools/common/fetch_apify_docs.ts`, line 51: ```typescript const isAllowedDomain = ALLOWED_DOC_DOMAINS.some((domain) => url.startsWi
