Technical details

A Cross-Site Request Forgery (CSRF) vulnerability exists in the Zohocorp Zoho Mail WordPress plugin before version 1.6.2. The vulnerability stems from insufficient validation of request origins on administrative actions within the plugin's configuration pages. An attacker can exploit this by inducing a logged-in administrator to visit a malicious website or click a crafted link, leading to unauthorized changes in plugin settings such as OAuth 2.0 credentials, 'From' email addresses, or mail server regions. The attack requires network connectivity and user interaction from an authenticated user. The issue is resolved in version 1.6.2.
