There is a stored Cross-site Scripting vulnerability in Esri Portal for ArcGIS Enterprise Sites versions 10.9.1 – 11.4 that may allow a remote, authenticated attacker to inject malicious a file with an embedded xss script which when loaded could potentially execute arbitrary JavaScript code in the victim’s browser.
