It acts as security theater, as it misleads linters while executing untrusted input via the bash wrapper. The vulnerability was still present in `sandboxed_web_e2e.py`. **Prevention:** Remove `/bin/bash` wrapper from `subprocess` calls in CI scripts. Always use `shlex.split(command)` to safely parse strings into a list of arguments and pass the list directly to `subprocess.Popen` or `subprocess.run`. +## 2026-08-10 - Unconditionally Redact Sandbox Logs +**Vulnerability:** Information Disclosure / Secret Leakage +**Learning:** Printing raw subprocess outputs (`stdout` and `stderr`) directly in sandboxed CI execution scripts can expose secrets in logs when commands fail or time out. Using conditional imports (`ImportError` fallback) for redaction tools can lead to silent failures where secrets are not scrubbed if the tool fails to load. +**Prevention:** Always ensure the repository root is on `sys.path` and unconditionally import `redact_text` from `scripts.ci.redact_sensitive_log`.
