CVE-2026-23545Public exploitNetwork attack vector

Unauthenticated cache manipulation via exposed AJAX handlers

Published Feb 19, 2026 · Updated Feb 19, 2026

Missing authorization in Aruba HiSpeed Cache 3.0.4 and earlier allows remote attackers to alter cache and optimization settings. Administrative AJAX handlers are registered through unauthenticated wp_ajax_nopriv hooks, while the reset-options handler also omits nonce verification. No account or user interaction is required; exposed operations include purging caches, resetting options, and changing optimization behavior.
