-
Needs Review Some areas of concern detected. Review the full issues report and weigh the risks before installing on production.
-
High Risk Significant quality or security problems found. Exercise caution — check the details carefully before using this plugin.

Detected Issues
| Severity | Category | Message | File | Fix Guidance |
|---|---|---|---|---|
| ERROR | SECURITY | Declared minimum PHP 5.6 is end-of-life and has known unpatched security vulnerabilities. |
Quick
Raise minimum PHP requirement to at least 8.1 and update plugin metadata.
Moderate
Refactor incompatible code paths and remove legacy polyfills tied to EOL PHP.
Advanced
Continuously test and enforce supported PHP baselines via CI and release policy.
|
|
| NOTICE | REPO | Plugin package does not include a license file. |
Quick
Add a LICENSE or COPYING file so distribution terms are explicit.

Add automated linting, CI checks, and team review guidance so this issue class is prevented in future releases.
|
|
| WARNING | SECURITY | Raw superglobal access detected. | app/init/notices.php |
Quick
Wrap direct request values with sanitization and nonce verification in the affected code path.
Moderate
Centralize request normalization in helper methods so handlers consume validated input only.
Advanced
Adopt typed request DTOs and automated security lint checks for unsanitized superglobal access.
|
| WARNING | SECURITY | Direct database query detected without an immediately visible $wpdb->prepare() wrapper. | app/Core/Uninstall.php |
Quick
Wrap dynamic SQL arguments with $wpdb->prepare() in the flagged query.
Moderate
Refactor repeated SQL into repository/helper methods that enforce prepared statements by default.
Advanced
Add integration tests and static checks that fail builds when direct dynamic SQL is introduced.
|
| WARNING | SECURITY | Use of unserialize() detected. | app/Utils/Helpers.php |
Quick
Switch the flagged payload to JSON decoding where practical.
Moderate
If serialization is required, enforce allowed_classes=false and strict input validation before parsing.
Advanced
Move state transfer to signed/typed schemas and add security tests for malformed payloads.
|
| NOTICE | REPO | Translation functions are present, but no textdomain loader was detected. |
Quick
Call load_plugin_textdomain() during plugin bootstrap so translations can be loaded.
Moderate
Apply the same remediation pattern across repo findings and re-scan to confirm notice issues drop.
Advanced
Add automated linting, CI checks, and team review guidance so this issue class is prevented in future releases.
