SHELL-016Low severity-4 points

'read' prompts for a password without -s

Part of Security, which counts for 30% of the overall score. When this check fires it deducts 4 points from that category, once per scan, no matter how many places it turns up.

What it detects

read -p "..." whose prompt text asks for a password/secret/token, without also passing -s, echoes every keystroke to the terminal as the user types it. Anyone shoulder-surfing or reviewing a captured terminal session/asciinema recording sees the credential in plain sight. Add -s so the input is silent.

Why it matters

read -p "..." whose prompt text asks for a password, secret, or token, without also passing -s, echoes every keystroke to the terminal as the user types it. Anyone looking over their shoulder, or reviewing a captured terminal session, a CI log, an asciinema recording, a screen-share, sees the credential appear in plain text.

How to fix it

Add -s to the read call so the input is silent (read -sp "Enter database password: " DB_PASSWORD). Since -s also suppresses the newline the user's Enter key would normally produce, follow it with a bare echo so the next output does not run onto the same line.
