# Pre-Deploy AI Audit — v2.1.6
**Plugin slug:** robotstxt-smtp-amazonses
**Version:** 2.1.6
**Minimum PHP:** 8.2
**Minimum WP:** 5.7
**Architecture:** Single-class OOP, namespace `Robotstxt_SMTP_AmazonSES`
**Exposes:** AJAX-style admin-post handlers, Settings API filter, WP-Cron hook
**Target:** Private / commercial
**Audit scope:** Full diff from 5ee811d (initial tooling commit) to HEAD — covers all changes introduced in this session.
---
## 1. SECURITY
### 1.1 handle_clear_credential() — new in 2.1.6
- **File:** `includes/class-plugin.php:1793`
- **Nonce:** `wp_verify_nonce()` with GET input via `wp_unslash()`. ✓
- **Capability:** `current_user_can('manage_options')` / `manage_network_options` based on scope. ✓
- **Scope validation:** `sanitize_key(wp_unslash($scope_raw))` before comparison. ✓
- **Redirect:** `wp_safe_redirect(add_query_arg([...], admin_url('admin.php')))` — both `$page_slug` and `$cleared_key` are hardcoded literals, not from user input. ✓
- **Option update:** uses `update_option()` / `update_site_option()` (WordPress API). ✓
- **ABSPATH guard:** present in main file. ✓
### 1.2 display_clear_key_notice() — new in 2.1.6
- **File:** `includes/class-plugin.php:1861`
- `FILTER_UNSAFE_RAW` used to read `robotstxt_smtp_amazonses_cleared`. Value is checked with strict equality (`'access_key'` / `'secret_key'`) before any output. Output escaped with `esc_html()`. No XSS path. ✓
- Notice only rendered when `get_current_screen()->id` contains `'robotstxt-smtp'`. ✓
### 1.3 Credential validation change (2.1.5)
- **File:** `includes/class-plugin.php:14731537`
- Blocking only on `InvalidClientTokenId`, `SignatureDoesNotMatch`, `InvalidAccessKeyId` — correct. AWS authentication errors that definitively prove wrong credentials.
- All other `AwsException` errors (wrong region, missing IAM permission) and `Throwable` errors (network) now allow saving. `unset($exception)` used to satisfy PHPCS empty-catch requirement. ✓
- No sensitive data exposed in error messages — access key masked in debug context. ✓
### 1.4 Reply-to clearing (2.1.5)
- **File:** `includes/class-plugin.php:1269`
- `sanitize_email(trim($options['reply_to_email']))` before setting to empty. ✓
- Only acts when key `reply_to_email` exists in submitted `$options`. ✓
### 1.5 Dependency check / missing parent notice (2.1.5)
- **File:** `robotstxt-smtp-amazonses.php:82`
- Pure output using `esc_html__()`. No user input read. ✓
- Registered on `admin_notices` and `network_admin_notices` only when parent class is absent. ✓
### 1.6 Previously existing code — no regressions found
- All form field renders use `esc_attr()` / `esc_html_e()`. ✓
- `wp_nonce_field()` / `check_admin_referer()` not needed here (Settings API handles nonces for save; admin-post handlers use `wp_verify_nonce()`). ✓
- No `eval()`, `base64_decode()`, `system()`, `exec()`, `unserialize()`, `extract()`. ✓
- Direct file access prevention on all PHP files. ✓
---
## 2. ROBUSTNESS & FATAL ERRORS
- `handle_clear_credential()` sets `$this->clearing_field` before `add_filter()` and unconditionally clears it after `update_option()`. If `update_option()` fails (returns false, does not throw), the priority-11 filter is still removed. No filter leak risk. ✓
- `force_clear_credential()` only acts when `$this->clearing_field !== null`. Safe to call even if left registered by accident. ✓
- All new code requires PHP 8.2 (`?string` property type). Declared minimum matches. ✓
- `plugin_loaded` → dependency check → class file included → `run()`: no class can be called before it's required. ✓
- `load_plugin_textdomain()` registered on `init` from main file (not from class), so it fires even when parent plugin is absent and the notice needs translating. ✓
---
## 3. COMPATIBILITY & CONFLICTS
- Multisite: both `get_site_option()` / `update_site_option()` and `get_option()` / `update_option()` paths implemented. `is_network_admin()` used for scope detection in field render, mirroring the parent plugin's password-clear pattern. ✓
- No assumptions about sidebars, widgets, or block themes. ✓
- `Requires Plugins: robotstxt-smtp` header enforced by WP 6.5+; PHP-level fallback added for WP 5.76.4. ✓
---
## 4. WORDPRESS CODING STANDARDS
- All new functions prefixed with `robotstxt_smtp_amazonses_`. ✓
- All new methods documented with `@since 2.1.6`. ✓
- No logic in constructor. ✓
- PHPCS passes with zero errors. ✓
---
## 5. INTERNATIONALIZATION
- `load_plugin_textdomain()` on `init`. ✓
- `.pot` regenerated with `wp i18n make-pot` (WP-CLI 2.12.0). ✓
- `es_ES` and `ca` translations complete: all new strings translated, fuzzy entries resolved. ✓
- Textdomain literal string `'robotstxt-smtp-amazonses'` — no variables. ✓
---
## 6. PERFORMANCE
- No N+1 queries introduced. ✓
- `delete_site_transient(get_quota_cache_key())` called after credential clear — avoids stale quota display. ✓
- `$client_cache` keyed by `md5(access_key|secret_key|region)` — SES clients re-used within a request. ✓
- All new admin-post handlers exit early on scope/nonce/capability failure before touching the DB. ✓
---
## 7. DATABASE & MIGRATIONS
- No custom tables. All data in parent plugin's option. ✓
- `uninstall.php` delegates to parent plugin. ✓
---
## 8. ASSETS & FRONTEND
- No JS or CSS added. ✓
- Clear buttons render as `<a class="button button-secondary">` — standard WP admin styling, no inline script. ✓
- `esc_url(wp_nonce_url(...))` used for button href. ✓
---
## 9. DEVOPS / RELEASE ARTIFACTS
- Version consistent across plugin header, `ROBOTSTXT_SMTP_AMAZONSES_VERSION`, `readme.txt`, `update.json`. ✓
- `Stable tag` matches `Version`. ✓
- `changelog.txt` and `readme.txt` follow template (date, categories, Compatibility, Tests). ✓
- `composer audit` — no CVEs. ✓
- `bin/deploy.sh` excludes dev files, phpstan config, composer.json/lock, `.claude/`, `.git`. ✓
---
## 10. PUBLIC API & BACKWARD COMPATIBILITY
- New public methods: `handle_clear_access_key()`, `handle_clear_secret_key()`, `force_clear_credential()`, `display_clear_key_notice()`, `get_cached_ses_quota()`. All additive, no removals. ✓
- `get_quota_cache_key()` remains public static — parent plugin accesses it. ✓
- No changes to filter/action signatures. ✓
- Removed: `apply_ses_quota_to_rate_limits()` — was unused private method. ✓
---
## WARNINGS
- **[WARNING] RESOLVED** `includes/class-plugin.php:1873``FILTER_UNSAFE_RAW` changed to `FILTER_SANITIZE_SPECIAL_CHARS` + `sanitize_key()` for the `robotstxt_smtp_amazonses_cleared` query parameter.
---
## FINAL EXECUTIVE SUMMARY
1. **Overall status:** ✅ PASS
2. **Top mandatory fixes before tagging:** None. All [CRITICAL] issues: 0.
3. **Estimated security risk:** Low.
4. **Version recommendation:** Safe to mark as stable.

[x] Safelist validation used for finite option sets — scope param uses sanitize_key() + strict equality
[x] Strict type checking used (===, in_array with true parameter)
[x] Validation performed BEFORE any action or processing
[x] Helper functions used: is_email(), sanitize_key()
INPUT SANITIZATION
[x] sanitize_text_field() for single-line text — credentials
[x] sanitize_textarea_field() for multi-line text — n/a
[x] sanitize_email() for email addresses — reply_to_email

[x] sanitize_url() for URLs — n/a (no URL inputs)
[x] sanitize_file_name() for filenames — n/a
[x] wp_kses() / wp_kses_post() for HTML content — n/a
OUTPUT ESCAPING (Escape Late)
[x] esc_html() for HTML element content

[x] esc_js() for inline JavaScript — n/a
[x] Combined i18n+escape functions (esc_html__(), esc_attr_e())
[x] Escaping performed at output time, not before storage
CSRF PROTECTION (Nonces)

[x] Appropriate capability selected
FILE OPERATIONS
[x] Direct file access prevention on all PHP files (ABSPATH guard)
DANGEROUS FUNCTIONS
[x] No eval() usage
