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.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check LiteSpeed Cache plugin version
    In WordPress admin, go to Plugins > Installed Plugins and find LiteSpeed Cache, or check the version in the plugin header file (wp-content/plugins/litespeed-cache/litespeed-cache.php)
    Affected if Version is 5.7.0 or lower (versions prior to 5.7.0.1)
  2. Verify LiteSpeed Cache plugin is active
    In WordPress admin, confirm LiteSpeed Cache shows as 'Active' under the plugin status
    Affected if Plugin is active and version is vulnerable
  3. Test unauthenticated access to admin AJAX endpoints
    Send a request to wp-admin/admin-ajax.php?action=litespeed_cache_action without authentication cookies, where 'litespeed_cache_action' represents any LiteSpeed Cache AJAX action (e.g., optn, cloud, etc.)
    Affected if The endpoint returns successful response or valid data instead of requiring authentication
  4. Check if privileged actions are accessible without capability verification
    Review network requests when LiteSpeed Cache features are used - attempt cache-related operations (like cache purge, optimization, or settings changes) as an unauthenticated user or subscriber-level user
    Affected if Actions execute successfully without proper WordPress capability checks (like 'manage_options')
  5. Inspect LiteSpeed Cache settings exposure
    Access the LiteSpeed Cache settings page (wp-admin/admin.php?page=litespeed-cache) while logged out or as a low-privilege user
    Affected if Settings pages or sensitive options are accessible without proper authorization

The environment is affected if LiteSpeed Cache version is 5.7.0 or lower AND admin AJAX endpoints or admin actions are accessible to unauthenticated or unauthorized users.
