CVE-2026-104083 [MEDIUM] – SmarterMail before build 9777 contains a stored mutation cross-site scripting vulnerabilit

SmarterMail before build 9777 contains a stored mutation cross-site scripting vulnerability that allows remote attackers to inject executable script by placing payloads inside a element nested within MathML foreign content ($), which the custom HTML sanitizer treats as inert CDATA text but browsers reparse as live markup. Attackers can deliver a crafted calendar (iCal) message containing an payload that executes automatically in the recipient’s webmail session at /interface/message-iframe when the message is opened, enabling script execution and data exfiltration unconstrained by the interface’s permissive Content-Security-Policy. 相关文章 国产服务器的散热与功耗实战2026年9月27日 国产内存、硬盘、网卡、RAID 卡的选型与兼容性2026年9月27日 信创环境的人员技能转型2026年9月27日 信创环境的补丁与版本管理2026年9月27日 $
