Name of the Vulnerable Software and Affected Versions Tennis Court Bookings plugin for WordPress versions prior to 1.2.8

Description The Tennis Court Bookings plugin for WordPress is susceptible to Stored Cross-Site Scripting through admin settings. Insufficient input sanitization and output escaping allows authenticated attackers with administrator-level permissions or higher to inject arbitrary web scripts into pages. These scripts will execute when a user accesses the injected page. This issue only impacts multi-site installations and those where unfiltered html has been disabled.

Recommendations Update the Tennis Court Bookings plugin to version 1.2.8 or later.
