ICEWARP 10.3.4 and 11.0.0.0 contains a cross-site scripting vulnerability that allows attackers to inject malicious HTML elements into emails by embedding base64-encoded payloads in object and embed tags. Attackers can craft emails containing data URIs with embedded scripts that execute in the client when the email is viewed, compromising user sessions and stealing sensitive information.
