What is CVE-2023-48115?

A vulnerability in SmarterMail allows for stored DOM cross-site scripting (XSS) due to a flaw in the XSS protection mechanism. When messageHTML and messagePlainText are set in the same request, the user can exploit this oversight to execute harmful scripts in the context of the web application's domain, potentially affecting all users interacting with the compromised email content. This could lead to data theft and unauthorized actions, highlighting the importance of regular security updates to mitigate such risks. For further details, refer to the official release notes and the in-depth write-up on this issue.
