CVE-2026-23694
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAruba HiSpeed Cache (aruba-hispeed-cache) WordPress plugin versions prior to 3.0.5 contain a cross-site request forgery (CSRF) vulnerability affecting multiple administrative AJAX actions. The handlers for ahsc_reset_options, ahsc_debug_status, and ahsc_enable_purge perform authentication and capability checks but do not verify a WordPress nonce for state-changing requests. An attacker can induce a logged-in administrator to visit a malicious webpage that submits forged requests to admin-ajax.php, resulting in unauthorized resetting of plugin settings, toggling of the WordPress WP_DEBUG configuration, or modification of cache purging behavior without the administrator’s intent.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Aruba HiSpeed Cache WordPress plugin versions before 3.0.5 have a CSRF vulnerability in three administrative AJAX endpoints (ahsc_reset_options, ahsc_debug_status, ahsc_enable_purge). Although these handlers verify user authentication and capabilities, they lack WordPress nonce verification, allowing attackers to forge requests by tricking logged-in administrators into visiting malicious pages.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed plugin versionLocate the Aruba HiSpeed Cache plugin directory (typically wp-content/plugins/aruba-hispeed-cache) and open the main PHP file to read the Version header, or check the WordPress admin Plugins page for the installed versionAffected if The version listed is below 3.0.5 (e.g., 3.0.4, 3.0.3, etc.)
-
Verify AJAX endpoint handlers existExamine the plugin source code for the three AJAX handlers: ahsc_reset_options, ahsc_debug_status, and ahsc_enable_purge. These are typically registered via add_action('wp_ajax_ahsc_reset_options', ...) and similar callsAffected if These three AJAX action handlers are present in the plugin code
-
Check for nonce verification in AJAX handlersOpen the PHP file containing the AJAX handler functions and inspect each of the three endpoints (ahsc_reset_options, ahsc_debug_status, ahsc_enable_purge) for the presence of a nonce check such as check_ajax_referer() or wp_verify_nonce()Affected if None of the three handlers contain nonce verification calls (the code lacks check_ajax_referer or wp_verify_nonce)
A user is affected if the Aruba HiSpeed Cache plugin version is below 3.0.5 AND the three AJAX endpoints (ahsc_reset_options, ahsc_debug_status, ahsc_enable_purge) exist without nonce verification checks in the code

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedUpgrade to version 3.0.5 or later which implements proper nonce verification for state-changing AJAX requests.
