Description
Authenticated users with workflow execution privileges can exploit the Gmail (v1) and Brevo nodes by providing an expression that resolves to an object containing a
path or href property. Because the mail composer does not verify that the message content is a string, it may read a local file accessible to the process or perform a Server-Side Request Forgery (SSRF)—where the server is coerced into making an unauthorized request to an internal URL—and attach the resulting data to the outgoing message.Recommendations
Update to version 1.123.73 or later.
Update to version 2.35.4 or later.
Update to version 2.36.2 or later.
