CVE-2026-107800 · Severity: medium · CVSS 5.4 · Published 2026-10-08

Jivejdon is a notebook and collaboration platform that allows users to send private messages. A vulnerability in the message display component allows authenticated users to inject malicious script into private short messages. When a recipient opens the crafted message, the script executes in their browser, potentially allowing attackers to steal session data or perform actions on behalf of the recipient.

## Technical details

The vulnerability is a stored cross-site scripting (XSS) flaw in receiveshortmessage.jsp where message bodies are rendered without HTML encoding via the filterMessageBody property. The ToolsUtil.convertURL() function passes user-supplied message content through unchanged, and the JSP uses bean:write with filter="false" to output the message body directly to the HTML response. An authenticated attacker can send a short message containing script tags, which will execute in the recipient's browser when the message is opened.
