Ringkasan
Use when reading any external input in WordPress — $_GET, $_POST, $_REQUEST, $_COOKIE, REST params, shortcode/block attributes, option/meta values, or remote API responses. Unslashes then sanitizes to the correct type (sanitize_text_field, sanitize_email, absint, sanitize_key, wp_kses_post, esc_url_raw) and validates values against expected sets. Apply proactively before storing or using any untrusted value.

Input sanitization & validation
When to use this skill
Use this skill whenever a value enters your code from outside:
- Superglobals:
$_GET,$_POST,$_REQUEST,$_COOKIE,$_SERVER. - REST API parameters, AJAX payloads, form fields.
- Shortcode attributes, block attributes, widget settings.
- Values read back from
get_option, post meta, or user meta that originated from users. - Bodies returned by remote APIs (
wp_remote_get, etc.).
Sanitize on input, escape on output — two different jobs. This skill covers input;
see output-escaping for output.
Core principles (and why they matter)
- All external input is untrusted. Even data from your own admin screens can be forged (CSRF) or tampered with. Sanitize regardless of source.
- Unslash before sanitizing. WordPress adds slashes to superglobals. Calling
wp_unslash()first prevents corrupted data (it\'sinstead ofit's) and ensures sanitizers see the real value. - Sanitize to the expected type. A function that expects an integer should call
absint(); an email,sanitize_email(). Type-appropriate sanitizing shrinks the attack surface far more than a generic catch-all. - Validation ≠ sanitization. Sanitizing cleans a value; validating rejects values
that don't belong. Use both: sanitize the shape, then validate against allowed sets
(
in_arraywith strict comparison, range checks,is_email). - Prefer allowlists over blocklists. Define what is permitted, reject the rest.
- Sanitize rich content with
wp_kses/wp_kses_post, never withstrip_tags—strip_tagsleaves dangerous attributes and is not XSS-safe.
Step-by-step implementation
- Confirm the value is set with
isset()/ null coalescing and a safe default. - Unslash:
wp_unslash( $_POST['x'] ). - Sanitize to type: pick the function matching the data (see cheatsheet).
- Validate: check ranges, allowed values, formats; reject invalid input.
- Use or store the clean value. Re-escape when later output.
$status = isset( $_POST['status'] ) ? sanitize_key( wp_unslash( $_POST['status'] ) ) : '';
$allowed = array( 'draft', 'publish', 'pending' );
$status = in_array( $status, $allowed, true ) ? $status : 'draft'; // validate + fallback

Common AI mistakes / anti-patterns
Mistake 1 — Sanitizing without unslashing
// ❌ Insecure/buggy: slashes corrupt the value and bypass intent.
$name = sanitize_text_field( $_POST['name'] );
// ✅ Correct: unslash first.
$name = isset( $_POST['name'] ) ? sanitize_text_field( wp_unslash( $_POST['name'] ) ) : '';
Mistake 2 — Using strip_tags() as if it were XSS-safe
// ❌ Insecure: strip_tags keeps event handlers/attributes and is not escaping.
$bio = strip_tags( $_POST['bio'] );
update_user_meta( $user_id, 'bio', $bio );
// ✅ Secure: allow a known-safe subset with wp_kses_post (or a custom allowlist).
$bio = isset( $_POST['bio'] ) ? wp_kses_post( wp_unslash( $_POST['bio'] ) ) : '';
update_user_meta( $user_id, 'bio', $bio );
Mistake 3 — Wrong sanitizer for the type
// ❌ Insecure: text sanitizer on something that must be an integer / URL.
$post_id = sanitize_text_field( $_GET['post_id'] ); // "12 OR 1=1" survives as a string
$link = sanitize_text_field( $_POST['link'] ); // allows javascript: scheme
// ✅ Secure: type-correct sanitizers.
$post_id = absint( $_GET['post_id'] ?? 0 );
$link = esc_url_raw( wp_unslash( $_POST['link'] ?? '' ) ); // for storage; esc_url for output
Mistake 4 — Sanitizing but never validating
// ❌ Weak: clean string, but any value is accepted.
$role = sanitize_key( wp_unslash( $_POST['role'] ?? '' ) );
$user->set_role( $role ); // attacker sends "administrator"
// ✅ Secure: validate against an allowlist.
$role = sanitize_key( wp_unslash( $_POST['role'] ?? '' ) );
$allowed = array( 'subscriber', 'contributor', 'author' );
if ( ! in_array( $role, $allowed, true ) ) {
wp_die( esc_html__( 'Invalid role.', 'my-plugin' ), 400 );
}
$user->set_role( $role );
Mistake 5 — Sanitizing arrays as if they were scalars
// ❌ Buggy/insecure: passing an array to a scalar sanitizer.
$ids = sanitize_text_field( $_POST['ids'] ); // returns "" for arrays
// ✅ Correct: map the sanitizer across the array.
$ids = isset( $_POST['ids'] ) && is_array( $_POST['ids'] )
? array_map( 'absint', wp_unslash( $_POST['ids'] ) )
: array();
Mistake 6 — Open redirect via unvalidated URL
// ❌ Insecure: attacker can redirect to a phishing site.
$redirect = $_GET['redirect_to'];
wp_redirect( $redirect );
exit;
// ✅ Secure: validate redirect targets with wp_validate_redirect and use wp_safe_redirect.
$redirect = isset( $_GET['redirect_to'] ) ? esc_url_raw( wp_unslash( $_GET['redirect_to'] ) ) : '';
$redirect = wp_validate_redirect( $redirect, admin_url() );
wp_safe_redirect( $redirect );
exit;
Mistake 7 — Trusting the whole request array (mass assignment)
// ❌ Insecure: every client-supplied field is written through — including ones
// the form never rendered. A forged POST adds post_author or post_status=publish.
wp_update_post( wp_unslash( $_POST['post'] ) );
foreach ( $_POST['settings'] as $key => $value ) {
update_user_meta( $user_id, 'my_plugin_' . sanitize_key( $key ), $value );
}
// Inside an authenticated admin-post handler; the form uses
// wp_nonce_field( 'my_plugin_edit_post_' . $post_id ).
$raw = $_POST['post'] ?? null;
if ( ! is_array( $raw )
|| ! isset( $raw['ID'], $raw['post_title'], $raw['post_content'] )
|| ! is_string( $raw['ID'] )
|| ! is_string( $raw['post_title'] )
|| ! is_string( $raw['post_content'] )
) {
wp_die( 'Invalid payload.', '', array( 'response' => 400 ) );
}
$post_id = filter_var( wp_unslash( $raw['ID'] ), FILTER_VALIDATE_INT, array(
'options' => array( 'min_range' => 1 ),
) );
if ( false === $post_id ) {
wp_die( 'Invalid post ID.', '', array( 'response' => 400 ) );
}
check_admin_referer( 'my_plugin_edit_post_' . $post_id );
$post = get_post( $post_id );
if ( ! $post || 'post' !== $post->post_type || ! current_user_can( 'edit_post', $post_id ) ) {
wp_die( 'Forbidden.', '', array( 'response' => 403 ) );
}
// Build only the allowed fields. Never merge the request back into this array.
$data = array(
'ID' => $post_id,
'post_title' => sanitize_text_field( wp_unslash( $raw['post_title'] ) ),
'post_content' => wp_kses_post( wp_unslash( $raw['post_content'] ) ),
);
$result = wp_update_post( wp_slash( $data ), true );
if ( is_wp_error( $result ) ) {
wp_die( 'Update failed.', '', array( 'response' => 500 ) );
}
Mass assignment writes client-selected fields that the endpoint never intended to
expose. wp_update_post() does not perform the caller's capability check; its
post_author and post_status fields must not become writable by accident. A user
role is not a post field, but generic user/meta writers have analogous risks. Avoid
extract( $_POST ) too: it lets request keys overwrite local variables.
For REST routes, args validates declared parameters; it does not automatically
reject or remove undeclared parameters. Construct an explicit persistence payload
rather than forwarding $request->get_params(). The Settings API can store one
array option, but its sanitize_callback must validate shape and build an explicit
allowlist of nested fields. Authorization and CSRF protection remain separate.
Related: see the output-escaping skill for the redirect "escape" context and the
settings-options-security skill for recursively sanitizing nested option arrays.
Correct code examples
A complete reference of input types mapped to the correct sanitize/validate functions —
text, email, int, float, key, slug, URL, HTML, arrays, JSON — is in
references/sanitization-cheatsheet.md.
// Settings array sanitized field-by-field on save.
function my_plugin_sanitize_settings( $input ) {
$clean = array();
$clean['email'] = sanitize_email( $input['email'] ?? '' );
$clean['count'] = absint( $input['count'] ?? 0 );
$clean['enabled'] = ! empty( $input['enabled'] ) ? 1 : 0;
$clean['note'] = wp_kses_post( $input['note'] ?? '' );
if ( ! is_email( $clean['email'] ) ) {
$clean['email'] = '';
add_settings_error( 'my_plugin', 'bad_email', __( 'Invalid email.', 'my-plugin' ) );
}
return $clean;
}
Checklist
- Every superglobal read is guarded with
isset()and a default. -
wp_unslash()is applied before sanitizing superglobal data. - Each value uses the sanitizer matching its type (see cheatsheet).
- Rich HTML uses
wp_kses/wp_kses_post, neverstrip_tags, for safety. - Values are validated against allowed sets / ranges after sanitizing.
- Arrays are sanitized element-by-element (
array_map). - URLs use
esc_url_raw()for storage (esc_url()for display). - Bulk updates validate container/scalar shapes, authorize each target object, and build explicit field allowlists.
- Settings API registrations supply a
sanitize_callback.
