CVE-2026-107797 · Severity: medium · CVSS 6.1 · Published 2026-10-08

Jivejdon is a forum and notebook application that allows users to create and share content. An attacker can craft malicious links containing JavaScript code in the "to" and "tag" parameters, which are inserted unsanitized into inline JavaScript in the page. When an authenticated user clicks the link, the attacker's code executes in their browser session, potentially allowing account compromise or data theft.
