CVE-2026-19337 Details
Description
A vulnerability was determined in adenot mcp-google-search up to 0.3.1. Impacted is an unknown function of the file src/index.ts of the component read_webpage. Executing a manipulation of the argument url can lead to server-side request forgery. The attack is restricted to local execution. This patch is called f071d491b685011ca04e8ab8d586fc65f86bcee1. It is advisable to implement a patch to correct this issue.
A server-side request forgery (SSRF) vulnerability has been identified in the adenot mcp-google-search tool, specifically in versions up to 0.3.1. The issue arises in the 'read_webpage' functionality, where the 'url' parameter is not properly validated. This lack of validation allows users to manipulate the URL and make requests to internal services from the server's network position, potentially accessing sensitive information or services not available to the client.
Users are advised to update to version 0.3.1 or later, where this vulnerability has been fixed. The patch includes strict URL validation to block requests to loopback, private, link-local, and multicast IP ranges, as well as validation of redirect targets to mitigate SSRF risks.
