Description
Intermesh Group-Office before 6.8.181, 25.0.116, and 26.0.58 contains a stored cross-site scripting vulnerability in the email viewer due to a flawed regex in StringHelper::filterXSS. Remote attackers can send emails containing tags like svg/onload, which MessagePanel.js renders raw, executing script in the recipient's session when opened.
