+# Frontend: real plaintext credentials in committed scripts/show-credentials.sh
+
+**Severity:** low
+**Domain:** Security
+**Labels:** security, frontend, secrets, rotation-required
+
+## Description
+
+`frontend/scripts/show-credentials.sh:8` contains hardcoded credentials including the password `Moji6364`. If this account exists in any real environment, the password must be rotated.
+
+## Options
+
+1. Delete the scripts and rotate the password if the account is real.
+2. Replace hardcoded creds with env-var prompts.
+3. Keep scripts but move creds out and rotate.
+
+## Recommendation
+
+Remove the hardcoded credentials (use env-var prompts instead) and rotate the account password if it exists in any real environment.
