CyberRota Analysis
AI-GeneratedThe Bookly plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping in the bookly_speed_up_update_addons AJAX action, affecting all versions up to 27.7. This vulnerability allows unauthenticated attackers to inject malicious scripts that execute when an administrator accesses the logs, potentially compromising site integrity and user data. WordPress site administrators using the Bookly plugin should prioritize immediate updates to mitigate this risk.
Original NVD Description
The Online Scheduling and Appointment Booking System – Bookly plugin for WordPress is vulnerable to Stored Cross-Site Scripting via bookly_speed_up_update_addons AJAX action in all versions up to, and including, 27.7 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. The injection point is the bookly_speed_up_update_addons AJAX action, which is registered as wp_ajax_nopriv_* and therefore reachable without authentication; the payload is stored verbatim in the bookly_log.details column when a request is submitted without a valid signature, and executes when an administrator later views the Diagnostics → Logs page.
