CVE-2025-66032 (GCVE-0-2025-66032)

Vulnerability from cvelistv5 – Published: 2025-12-03 18:16 – Updated: 2025-12-03 19:11

Title

Claude Code Command Validation Bypass Allows Arbitrary Code Execution

Summary

Claude Code is an agentic coding tool. Prior to 1.0.93, Due to errors in parsing shell commands related to $IFS and short CLI flags, it was possible to bypass the Claude Code read-only validation and trigger arbitrary code execution. Reliably exploiting this requires the ability to add untrusted content into a Claude Code context window. This vulnerability is fixed in 1.0.93.

Severity

8.7 (High)
