CyberRota Analysis
AI-GeneratedThe ICS Calendar plugin for WordPress is susceptible to Reflected Cross-Site Scripting (XSS) due to inadequate input sanitization and output escaping in the 'htmltagtitle' parameter across all versions up to 12.0.9. This vulnerability allows unauthenticated attackers to inject malicious scripts into web pages, potentially compromising user interactions if they are tricked into clicking a crafted link. WordPress site administrators using this plugin should prioritize patching to mitigate the risk of exploitation.
Original NVD Description
The ICS Calendar plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'htmltagtitle' parameter in all versions up to, and including, 12.0.9 due to insufficient input sanitization and output escaping. This makes it possible for 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 vulnerability is reachable via the unauthenticated wp_ajax_nopriv_r34ics_ajax AJAX action, which accepts attacker-controlled js_args values merged over stored shortcode configuration without nonce verification, allowing the htmltagtitle key to bypass the normal shortcode allowlist check.
