The YS LeadGen plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.1.4 due to the 'ysleadgen_get_captured_data' AJAX action being accessible to unauthenticated users. This makes it possible for unauthenticated attackers to retrieve all captured form submission data, including personally identifiable information (PII) such as names, email addresses, and message content submitted through YS LeadGen forms.
