CyberRota Analysis
AI-GeneratedThe Contact Form by Supsystic plugin for WordPress is vulnerable to Stored Cross-Site Scripting due to inadequate input sanitization and output escaping, affecting all versions up to 1.10.2. This vulnerability allows unauthenticated attackers to inject malicious scripts that execute when users access compromised pages, potentially leading to data theft or session hijacking. WordPress site administrators using this plugin should prioritize patching or updating to mitigate the risk of exploitation.
Original NVD Description
The Contact Form by Supsystic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via IP Address Header in all versions up to, and including, 1.10.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An unauthenticated attacker can first call the 'updateNonce' action — which is accessible without authentication due to its absence from the plugin's permission list — to obtain a valid nonce, then submit a contact form with a malicious payload in a spoofed IP header such as X-Forwarded-For.
