SCA: security update for github.com/googleapis/mcp-toolbox (GHSA-76g7-m3xw-x9gr)
critical Tenable Self-Hosted Container Security Plugin ID 446254
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- The Model Context Protocol has a security warning advising servers to validate the "Origin" header on all
incoming connections to prevent DNS rebinding attacks. Prior to the v0.25.0 release, users had no way to
validate the origin's host. In v0.25.0, a new "--allowed-hosts" flag was introduced alongside the existing
"--allowed-origins" flag, enabling users to specify permitted hosts at server startup. Both flags default
to "*", allowing users to implement strict access controls as needed without breaking existing setups. If
either flag is set to "*", the server will output a startup warning about potential vulnerabilities.
Documentation has also been updated to highlight these security considerations. (CVE-2026-11624)
Solution
Update the github.com/googleapis/mcp-toolbox library and its related packages to version 0.25.0 or later.See Also
