Shell Script Injection Protection + +**Issue**: Dynamic shell commands without proper escaping are vulnerable to injection. + +**Risk**: Attackers can break out of intended command structure to execute arbitrary commands. + +**Mitigation**: +- Use `escapeShellArg()` for any variable that becomes a shell argument +- Prefer structured APIs over shell interpolation when possible +- Use `set -euo pipefail` and error trapping +- Never pipe untrusted data directly to `eval`, `bash`, or similar + +**Example - BEFORE (unsafe)**: +```bash +agent_name=$1 +eval "run_agent_$agent_name" # VULNERABLE if $agent_name is user input +``` + +**Example - AFTER (safe)**: +```bash +agent_name=$1 +if [[ "$agent_name" =~ ^[a-z-]+$ ]]; then + "run_agent_$agent_name" # Still safer than eval, but validate first +else + echo "Invalid agent name" + exit 1 +fi +``` + +### 4. Hardcoded Credentials & Secrets + +**Issue**: API keys, tokens, or credentials should never be committed to version control. + +**Risk**: Exposed credentials can be abused by attackers; difficult to revoke if in git history. + +**Mitigation**: +- Use `.env` files locally (add to `.gitignore`) +- Store secrets in GitHub Secrets or external secret managers +- Scan commits with `git-secrets` or similar tools +- Never commit `.env`, `.credential`, or similar files +- Rotate credentials if accidentally exposed + +**Safe pattern**: +```bash +# Load from environment, not from file +if [[ -z "${AGENT_API_KEY:-}" ]]; then + echo "Error: AGENT_API_KEY not set.
