SCA: security update for @anthropic-ai/claude-code (GHSA-vp62-r36r-9xqp)

high Tenable Self-Hosted Container Security Plugin ID 440685

Description

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

 - Claude Code is an agentic coding tool. Prior to version 2.1.64, Claude Code's sandbox did not prevent
 sandboxed processes from creating symlinks pointing to locations outside the workspace. When Claude Code
 subsequently wrote to a path within such a symlink, its unsandboxed process followed the symlink and wrote
 to the target location outside the workspace without prompting the user for confirmation. This allowed a
 sandbox escape where neither the sandboxed command nor the unsandboxed app could independently write
 outside the workspace, but their combination could write to arbitrary locations, potentially leading to
 code execution outside the sandbox. Reliably exploiting this required the ability to add untrusted content
 into a Claude Code context window to trigger sandboxed code execution via prompt injection. Users on
 standard Claude Code auto-update have received this fix automatically. Users performing manual updates are
 advised to update to version 2.1.64 or later. (CVE-2026-39861)

Solution

Update the @anthropic-ai/claude-code library and its related packages to version 2.1.64 or later.
