SCA: security update for @anthropic-ai/claude-code (GHSA-fg94-h982-f3mm)

medium Tenable Cloud Security Plugin ID 443352

Description

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

 - Claude Code is an agentic coding tool. From 0.2.54 until 2.1.163, because the hostname huggingface.co was
 pre-approved as a bare hostname for the WebFetch tool, any path on that domain—including attacker-
 controlled model repositories—was auto-approved without a permission prompt or being subject to
 --allowedTools restrictions. An attacker able to inject untrusted content into a Claude Code context could
 direct it to issue WebFetch requests against attacker-controlled repository files (e.g.
 /resolve/main/config.json), which HuggingFace counts as downloads server-side, creating a covert out-of-
 band channel for encoding and exfiltrating data Claude can access such as files, environment variables, or
 command output. Reliably exploiting this required the ability to add untrusted content into a Claude Code
 context window. This vulnerability is fixed in 2.1.163. (CVE-2026-54316)

Solution

Update the @anthropic-ai/claude-code library and its related packages to version 2.1.163 or later.
