SCA: security update for mcp-server-git (GHSA-vjqx-cfc4-9h6v)

medium Tenable Cloud Security Plugin ID 438118

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Model Context Protocol Servers is a collection of reference implementations for the model context protocol
 (MCP). In mcp-server-git versions prior to 2026.1.14, the git_add tool did not validate that file paths
 provided in the files argument were within the repository boundaries. Because the tool used GitPython's
 repo.index.add() rather than the Git CLI, relative paths containing `../` sequences that resolve outside
 the repository were accepted and staged into the Git index. Users are advised to upgrade to 2026.1.14 or
 newer to remediate this issue. (CVE-2026-27735)
