Summary
CVE-2025-66032 affects Claude Code, an agentic coding tool, before version 1.0.93. Errors in parsing shell commands related to $IFS and short CLI flags let an attacker bypass the read-only validation and trigger arbitrary code execution. Exploiting it reliably requires the ability to add untrusted content into the Claude Code context window.
Mitigation
Fixed in 1.0.93.
