title: Claude Code has a Workspace Trust Dialog Bypass via Repo-Controlled Settings File
description: Documents a Claude Code workspace-trust bypass in which repository-controlled settings are resolved before the trust confirmation decision. Setting the default permission mode to bypassPermissions can suppress the first-open dialog and place the user into a permissive execution mode.

# Claude Code has a Workspace Trust Dialog Bypass via Repo-Controlled Settings File

- Advisory: GHSA-mmgp-wc2j-qcv7
- CVE: CVE-2026-33068
- Severity: high
- Published: 2026-03-19
- Updated: 2026-03-20

## Affected

- `@anthropic-ai/claude-code` (npm): < 2.1.53, fixed in 2.1.53

## Description

Claude Code resolved the permission mode from settings files, including the repo-controlled `.claude/settings.json`, before determining whether to display the workspace trust confirmation dialog. A malicious repository could set `permissions.defaultMode` to `bypassPermissions` in its committed `.claude/settings.json`, causing the trust dialog to be silently skipped on first open. This allowed a user to be placed into a permissive mode without seeing the trust confirmation prompt, making it easier for an attacker-controlled repository to gain tool execution without explicit user consent.

Users on standard Claude Code auto-update have received this fix already. Users performing manual updates are advised to update to the latest version.
