CVE-2025-65099 · Claude Code vulnerable to command execution prior to startup trust dialog
This page contains facts from public vulnerability sources. Check the original advisory before updating.
Claude Code is an agentic coding tool. Prior to version 1.0.39, when running on a machine with Yarn 3.0 or above, Claude Code could have been tricked to execute code contained in a project via yarn plugins before the user accepted the startup trust dialog. Exploiting this would have required a user to start Claude Code in an untrusted directory and to be using Yarn 3.0 or above. This issue has been patched in version 1.0.39.
