SCA: security update for @anthropic-ai/claude-code (GHSA-4vp2-6q8c-pvq2)

medium Tenable Cloud Security Plugin ID 443937

Description

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

 - Claude Code is an agentic coding tool. From 2.1.59 until 2.1.128, the Claude Code /copy command wrote
 responses to a hardcoded, predictable path (/tmp/claude/response.md) without UID isolation, randomness, or
 symlink protection. The file was created world-readable (0644) in a world-traversable directory (0755),
 allowing any local user to read a privileged user's Claude response, which could contain secrets or
 credentials. Additionally, because the path was static and predictable, a local attacker could pre-create
 the directory and plant a symlink at the expected file path, causing the privileged process to follow the
 symlink and overwrite an attacker-chosen file with the response text. Exploiting this required a local
 unprivileged user on the same system and a privileged user to run the /copy command. This vulnerability is
 fixed in 2.1.128. (CVE-2026-46406)

Solution

Update the @anthropic-ai/claude-code library and its related packages to version 2.1.128 or later.
