CVE-2025-31469
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 · uneditedMissing Authorization vulnerability in webrangers Clear Sucuri Cache clear-sucuri-cache allows Exploiting Incorrectly Configured Access Control Security Levels.This issue affects Clear Sucuri Cache: from n/a through <= 1.4.
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 · moderate confidenceMissing authorization vulnerability in the Clear Sucuri Cache WordPress plugin allows unauthenticated or improperly authorized users to trigger cache clearing operations. The plugin fails to implement proper capability checks and nonce verification on the clear-sucuri-cache AJAX endpoint, enabling attackers to exploit incorrectly configured access control security levels.

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.
-
Verify Clear Sucuri Cache plugin is installedCheck your WordPress plugins directory or use WP-CLI: wp plugin list --search='clear-sucuri-cache'Affected if The plugin appears in the list of installed plugins
-
Determine installed plugin versionLook in the plugin header (clear-sucuri-cache.php or similar) for the Version field, or use: wp plugin get clear-sucuri-cache --field=versionAffected if The version is known and can be compared to any patched version when available
-
Identify the AJAX endpoint handlerSearch plugin files for 'clear-sucuri-cache' string and locate the associated AJAX action hook (likely add_action('wp_ajax_clear-sucuri-cache' or 'wp_ajax_nopriv_clear-sucuri-cache'))Affected if The AJAX action hook exists in the plugin code
-
Check for capability verification in AJAX handlerExamine the AJAX callback function for current_user_capability or similar authorization check (look for functions like current_user_can(), check_admin_referer(), wp_verify_nonce())Affected if No capability check or nonce verification is found before cache clearing operations are performed
-
Verify if nopriv AJAX action is registeredSearch for 'wp_ajax_nopriv_clear-sucuri-cache' in the plugin code to see if unauthenticated access is enabledAffected if The nopriv action hook is registered, allowing unauthenticated users to trigger the endpoint
Your environment is affected if the Clear Sucuri Cache plugin is installed and the clear-sucuri-cache AJAX endpoint lacks proper capability checks and nonce validation, allowing unauthenticated or unauthorized cache clearing operations.

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.
From vendor dataImplement proper authorization checks (verify user capabilities) and nonce validation on all AJAX endpoints that perform cache operations. Users should update to a patched version once available and restrict access to the affected endpoint until remediated.
