CVE-2024-2842 is a vulnerability found in the Easy Appointments plugin for WordPress. This vulnerability affects all versions up to and including 3.11.18. It allows authenticated attackers with contributor-level access and above to inject arbitrary web scripts through the plugin's 'ea_full_calendar' shortcode, leading to stored cross-site scripting (XSS). The vulnerability arises due to insufficient input sanitization and output escaping on user-supplied attributes.

The potential danger this vulnerability poses to an organization is relatively low, with low impact on integrity and confidentiality, and no impact on availability. To remediate this vulnerability, it is recommended to update the Easy Appointments plugin to a version beyond 3.11.18, which addresses the issue by implementing proper input validation and output encoding techniques.
