Technical details

Stored cross-site scripting (CWE-79) vulnerability allows a low-privileged authenticated user to inject malicious JavaScript into form fields. The injected scripts persist in the application and execute in the context of other users' browsers when they access the affected pages, with the scope changed to cross-site impact. The attack requires user interaction (victim viewing the page) and the attacker must have low-level permissions to submit form data.
