WordPress · Bizcalendar Web · CVE-2024-1780
**Name of the Vulnerable Software and Affected Versions**
BizCalendar Web plugin for WordPress versions up to, and including, 1.1.0.19
**Description**
The issue is related to Reflected Cross-Site Scripting due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. The `tab` parameter is specifically vulnerable to this issue.
**Recommendations**
For versions up to, and including, 1.1.0.19, avoid using the `tab` parameter in affected pages until a fix is available. As a temporary workaround, consider implementing proper input sanitization and output escaping for the `tab` parameter to prevent arbitrary web script injection.
