What is CVE-2026-23614?

GFI MailEssentials AI versions before 22.4 are susceptible to a stored cross-site scripting vulnerability in the Sender Policy Framework IP Exceptions interface. An authenticated user can exploit this flaw by injecting malicious HTML or JavaScript code in the ctl00$ContentPlaceHolder1$pv2$txtIPDescription parameter on the SenderPolicyFramework.aspx page. This stored payload is later rendered in the management interface, enabling script execution within the context of a logged-in user, potentially compromising user data and system integrity.
