Vulnerability in wp-graphql/wp-graphql (CVE-2026-54768)

Summary

Vulnerability in wp-graphql/wp-graphql (CVE-2026-54768). Risk of unauthorized operations or information disclosure. Exploitable via sendPasswordResetEmail.

Original description

The description as published by the source.

Summary

The sendPasswordResetEmail mutation in WPGraphQL is explicitly designed to prevent user enumeration. The resolver in src/Mutation/SendPasswordResetEmail.php states in a code comment:

// We obsfucate the actual success of this mutation to prevent user enumeration.

The mutation always returns success: true regardless of whether the supplied username/email belongs to an existing user. The intended public output field is only success: Boolean.

However, a deprecated user field is still registered on the SendPasswordResetEmailPayload output type in src/Deprecated.php (lines 433-450). This deprecated field resolves to a full User object when the supplied username/email corresponds to an existing author-class user, and null otherwise — completely undermining the anti-enumeration design.

The @todo remove in 3.0.0 comment acknowledges the field is scheduled for removal, but it remains active in all 2.x releases, including current 2.14.1.

Discovered via source code review on May 29, 2026.

Details

The mutation resolver in src/Mutation/SendPasswordResetEmail.php:

$payload = ['success' => true, 'id' => null];
$user_data = self::get_user_data($input['username']);
if (!$user_data) {
    graphql_debug(...);
    return $payload;  // id stays null
}
// ...send email, then...
return ['id' => $user_data->ID, 'success' => true];

The intended public output field is only success. The id is internal-only state for downstream resolvers.
