The Salon Booking System – Appointment Booking for Salons, Barbershops & Spas plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sln[<checkout-field-key>]' parameter in all versions up to, and including, 10.31.9 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitation requires that the site administrator has configured at least one custom checkout field of type Html or File, which is a standard documented plugin feature.

The Salon Booking System – Free Version plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 10.30.32. This is due to missing or incorrect nonce validation on the setCustomText function. This makes it possible for unauthenticated attackers to inject arbitrary PHP code into the web-accessible translate-constants.php file within the plugin directory, enabling remote code execution on the server via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. sanitize_text_field() is applied to the POST 'value' parameter but does not neutralize the characters — single quotes, parentheses, semicolons, $, and [] — required to break out of the PHP string literal into which the value is interpolated before being written to disk via file_put_contents().

The Salon Booking System – Free Version plugin for WordPress is vulnerable to Arbitrary File Read in versions up to, and including, 10.30.25. This is due to the public booking flow accepting attacker-controlled file-field values and later using those stored values as trusted paths for email attachments. This makes it possible for unauthenticated attackers to read arbitrary local files and exfiltrate them via booking confirmation email attachments.

The 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.

The Salon booking system plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the SLN_Action_Ajax_ImportAssistants function along with missing authorization checks in all versions up to, and including, 10.2. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible.

The Salon booking system plugin for WordPress is vulnerable to unauthorized access and modification of data due to a missing capability check on several functions hooked into admin_init in all versions up to, and including, 9.9. This makes it possible for authenticated attackers with subscriber access or higher to modify plugin settings and view discount codes intended for other users.

The Salon booking system plugin for WordPress is vulnerable to arbitrary file deletion in all versions up to, and including, 9.8. This is due to the plugin not properly validating the path of an uploaded file prior to deleting it. This makes it possible for unauthenticated attackers to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution possible. This was partially patched in 9.9, and sufficiently patched in 10.0. CVE-2024-37231 appears to be a duplicate of this issue.
