Summary
The WPO365 Microsoft 365 Graph Mailer plugin for WordPress, in versions up to and including 6.2, is affected. An unauthenticated attacker can submit a crafted email subject through a mail-sending feature, such as a contact form, so that malicious scripts are stored and then run in the browser of any user who views the affected page.

Read the original description
The WPO365 | MICROSOFT 365 GRAPH MAILER plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Subject (via wp_mail/PHPMailer, e.g. CF7 your-subject)' parameter in all versions up to, and including, 6.2 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. The payload is stored without authentication via any mail-sending feature that forwards a submitter-controlled subject (e.g. a Contact Form 7 form) when the Graph Mailer is enabled but OAuth authorization has not been completed, a default state immediately after plugin activation.
