What: Sophisticated detection and escaping of dangerous shell constructs like heredocs and multiline strings How to use: This protection is automatic when Claude executes shell commands. It prevents injection attacks in complex scenarios:
# Heredocs are now safely handled
cat << EOF
$(potentially_dangerous_command)
EOF
# Multiline strings are properly escaped
echo 'line1
line2'Details:
- Detects heredoc patterns that could bypass normal escaping
- Identifies multiline strings that might hide malicious commands
- Applies context-aware escaping strategies
- Automatically adds stdin redirection (
< /dev/null) to prevent interactive command exploitation - Protects against arithmetic expansion and nested command substitution attacks
