Description
The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "editionarea" parameter when cfwpp_edit is set to 'js' or 'css' in the "cpabc_appointments_save_edition()" function.
