Claude Code v2.1.234 17 Aug 2026

Policy-helper subprocesses run in a scrubbed, pinned environment

Under the hood

Useful2 Signal3

Permissions

Policy helper subprocesses now run with a scrubbed, fixed environment rather than inheriting yours.

What

The helper that evaluates policy no longer inherits the parent process environment shape, and inline interpreters get a fixed environment: for sh, a deny-list of variables and prefixes is deleted, PATH is replaced with a fixed value and LC_ALL is set to C; for pwsh, PSModulePath, PATH, PATHEXT and COMSPEC are pinned and TERM is set to dumb. CLAUDE_CODE_VERSION is injected explicitly.

Details

The no-inherit behaviour comes from a new option threaded through the internal exec wrapper.
Failures now report structured codes such as bad_path, exit_nonzero and "no path or script configured".

Evidence

extendEnv

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
