SCA: security update for @anthropic-ai/claude-code (GHSA-7835-87q9-rgvv)
high Tenable Self-Hosted Container Security Plugin ID 445264
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- Claude Code is an agentic coding tool. From 2.1.38 until 2.1.163, Claude Code's worktree handling allowed
creation of worktrees named ".git" and navigation to worktrees outside the sandbox context, enabling git
directory confusion attacks. By exploiting symlink manipulation and git fsmonitor execution during
worktree operations, an attacker could overwrite files in the user's home directory (such as .zshenv),
leading to code execution outside of seatbelt sandbox restrictions. Reliably exploiting this required the
user to clone a malicious repository containing prompt injection content and run Claude Code against it.
This vulnerability is fixed in 2.1.163. (CVE-2026-55607)
Solution
Update the @anthropic-ai/claude-code library and its related packages to version 2.1.163 or later.See Also
