WordPress · Bus Ticket Booking With Seat Reservation · CVE-2023-4067
**Name of the Vulnerable Software and Affected Versions**
The Bus Ticket Booking with Seat Reservation plugin for WordPress versions up to, and including, 5.2.3
**Description**
The issue arises from insufficient input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts via the `tab date` and `tab date r` parameters. This enables attackers to execute scripts on pages if they can trick a user into performing a specific action, such as clicking on a link.
**Recommendations**
For versions up to, and including, 5.2.3, update to a version that addresses the insufficient input sanitization and output escaping issue.
As a temporary workaround, consider restricting access to the `tab date` and `tab date r` parameters to minimize the risk of exploitation.
