Appointment Booking Plugin
Monthly
The Appointment Booking Plugin for WordPress (all versions before 5.6.8) allows unauthenticated visitors to set privileged booking fields - including approval status - through the plugin's public booking funnel, silently bypassing the site's manual booking approval workflow. Any site relying on appointment approval as a gatekeeping mechanism can have that control subverted by any internet-accessible visitor with no credentials required. A publicly available proof-of-concept exists per WPScan; however, EPSS remains at 0.15% (5th percentile), indicating limited observed exploitation activity despite the trivially low attack complexity.
Cross-Site Request Forgery in the Appointment Booking Plugin for WordPress (versions before 5.6.3) allows an unauthenticated attacker to perform privileged administrative actions - including overwriting the booking-form configuration and disconnecting the connected payment gateway - by tricking a logged-in administrator into clicking a malicious link or visiting an attacker-controlled page. The root cause is absent CSRF nonce validation across multiple state-changing actions handled by the plugin's central request dispatcher. A publicly available proof-of-concept exists per the WPScan advisory, though EPSS sits at 0.10% (1st percentile), indicating negligible observed exploitation activity and no CISA KEV listing at time of analysis.
