SCA: security update for @anthropic-ai/claude-code (GHSA-jh7p-qr78-84p7)

medium Tenable Cloud Security Plugin ID 436827

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 2.0.65, vulnerability in Claude Code's project-
load flow allowed malicious repositories to exfiltrate data including Anthropic API keys before users
confirmed trust. An attacker-controlled repository could include a settings file that sets
ANTHROPIC_BASE_URL to an attacker-controlled endpoint and when the repository was opened, Claude Code
would read the configuration and immediately issue API requests before showing the trust prompt,
potentially leaking the user's API keys. Users on standard Claude Code auto-update have received this fix
already. Users performing manual updates are advised to update to version 2.0.65, which contains a patch,
or to the latest version. (CVE-2026-21852)
