SCA: security update for mcp-package-docs (GHSA-vf9j-h32g-2764)

high Tenable Self-Hosted Container Security Plugin ID 434788

Description

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

 - mcp-package-docs is an MCP (Model Context Protocol) server that provides LLMs with efficient access to
 package documentation across multiple programming languages and language server protocol (LSP)
 capabilities. A command injection vulnerability exists in the `mcp-package-docs` MCP Server prior to the
 fix in commit cb4ad49615275379fd6f2f1cf1ec4731eec56eb9. The vulnerability is caused by the unsanitized use
 of input parameters within a call to `child_process.exec`, enabling an attacker to inject arbitrary system
 commands. Successful exploitation can lead to remote code execution under the server process's privileges.
 The server constructs and executes shell commands using unvalidated user input directly within command-
 line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.).
 Commit cb4ad49615275379fd6f2f1cf1ec4731eec56eb9 in version 0.1.27 contains a fix for the issue, but
 upgrading to 0.1.28 is recommended. (CVE-2025-54073)
