CVE-2026-107801
Jivejdon through 5.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to execute JavaScript by uploading attachments with an attacker-supplied Content-Type.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
Description
Jivejdon through 5.0 contains a stored cross-site scripting vulnerability that allows authenticated attackers to execute JavaScript by uploading attachments with an attacker-supplied Content-Type. Attackers can upload a file declared as text/html, which UploadShowAction serves inline, and share its link to run JavaScript on the application's origin for viewing users.
