Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVE CVE-2024-2842
CVSS 6.4 (Medium)
Publicly Published March 28, 2024
Last Updated March 29, 2024
Researcher Krzysztof Zając - CERT PL

Description

The Easy Appointments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ea_full_calendar' shortcode in all versions up to, and including, 3.11.18 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
