OneSignal – Web Push Notifications

All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found '"oneSignal_options['serviceWorkerParam'] = { scope: '$swScope' };\n"'.

$_POST[$field] not unslashed before sanitization. Use wp_unslash() or similar

Functions declared in the global namespace by a theme/plugin should start with the theme/plugin prefix. Found: "admin_files".

Mismatched text domain. Expected 'onesignal-free-web-push-notifications' but got 'onesignal'.

Processing form data without nonce verification.

Missing $domain parameter in function call to __().

Global variables defined by a theme/plugin should start with the theme/plugin prefix. Found: "$is_migrated".

error_log() found. Debug code should not normally be used in production.

Detected usage of a non-sanitized input variable: $_POST['onesignal_v3_metabox_nonce']

Detected usage of a possibly undefined superglobal array index: $_POST['onesignal_notification_custom_content']. Check that the array index exists before using it.

In footer ($in_footer) is not set explicitly wp_enqueue_script; It is recommended to load scripts in the footer. Please set this value to `true` to load it in the footer, or explicitly `false` if it should be loaded in the header.

PHP file should prevent direct access. Add a check like: if ( ! defined( 'ABSPATH' ) ) exit;

parse_url() is discouraged because of inconsistency in the output across PHP versions; use wp_parse_url() instead.

A function call to __() with texts containing placeholders was found, but was not accompanied by a "translators:" comment on the line above to clarify the meaning of the placeholders.

wp_redirect() found. Using wp_safe_redirect(), along with the "allowed_redirect_hosts" filter if needed, can help avoid any chances of malicious redirects within code. It is also important to remember to call exit() after a redirect so that no other unwanted code is executed.

File operations should use WP_Filesystem methods instead of direct PHP filesystem calls. Found: fclose().

Scripts must be registered/enqueued via wp_enqueue_script()

The $text parameter must be a single text string literal. Found: $label
