CVE-2025-8492
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 · uneditedThe Salon Booking System, Appointment Scheduling for Salons, Spas & Small Businesses plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax function in all versions up to, and including, 10.22. This makes it possible for unauthenticated attackers to execute AJAX actions, including limited file uploads.
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 Salon Booking System WordPress plugin has a broken access control vulnerability where the ajax function lacks proper capability checks. This allows unauthenticated attackers to execute AJAX actions, including limited file uploads, due to missing authorization validation on the server-side endpoint.

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.
-
Confirm Salon Booking System plugin is installedNavigate to WordPress admin dashboard > Plugins > Installed Plugins. Look for 'Salon Booking System' in the plugin list. Note the version number displayed under the plugin name.Affected if The plugin is installed and the version is lower than 10.23 or the version cannot be determined.
-
Verify installed plugin version against fixed releaseIn the plugins list, locate the version number for Salon Booking System. Compare this to version 10.23 which contains the security fix. If the version shown is earlier than 10.23, the vulnerability is present.Affected if Installed version is below 10.23.
-
Check ajax endpoint accessibilityReview the plugin files for ajax actions (typically in main plugin PHP file or separate ajax handler files). Look for hooks like 'wp_ajax_' and 'wp_ajax_nopriv_' that register unauthenticated ajax callbacks. Verify if capability checks (using current_user_can or similar) are present in these handlers.Affected if Ajax handlers exist that can be accessed without authentication (wp_ajax_nopriv_) and lack capability validation checks.
-
Inspect file upload functionalityExamine the plugin code for file upload handlers triggered via ajax. Look for functions handling file uploads that are hooked to unauthenticated ajax actions. Check if these upload functions validate user permissions before processing uploads.Affected if File upload handlers are hooked to unauthenticated ajax endpoints without proper authorization validation.
A user is affected if the Salon Booking System plugin is installed with a version lower than 10.23 and unauthenticated ajax endpoints with file upload capability exist without proper capability checks.

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 dataUpdate the plugin to version 10.23 or later which contains the security fix. If immediate update is not possible, consider disabling the plugin or implementing web application firewall rules to block unauthenticated access to the affected ajax endpoints.
