Loading vulnerability…
CVE-2025-59978 is a stored cross-site scripting vulnerability in Juniper Networks Junos Space caused by improper neutralization of user-supplied input during web page generation. Junos Space fails to adequately sanitize and encode attacker-controlled data before rendering it in the web interface, allowing malicious script content to be stored in application data fields and later executed when viewed by another user. When an administrative user loads a page containing the stored payload, the script executes in the context of that user’s authenticated browser session and inherits the user’s administrative privileges. The issue affects all Junos Space versions prior to 24.1R4.
