Short explanation
The Turisbook Booking System WordPress plugin versions up to 1.3.8 lack authorization and CSRF checks when saving settings, and one setting is output without sanitization on an admin page. This allows an unauthenticated user to perform a stored XSS exploit and hijack administrator sessions.
Compromised admin sessions can lead to site integrity loss and exposure of user data.
What should be done?
- Upgrade to the latest version when vendor releases a fix (S0)
- Implement proper authentication and CSRF protection
- Sanitize and escape setting values before output (S0)
- Conduct security testing and XSS scanning
The sources give limited detail on some technical conditions. Review the chain of evidence below before deciding how to act.
