CVE-2019-11818
Alkacon OpenCMS v10.5.4 and before is affected by stored cross site scripting (XSS) in the module New User (/opencms/system/workplace/admin/accounts/user_new.jsp).
Does this matter?
Lower severity and a low EPSS score (0.77%). Track it; it rarely justifies an emergency change on its own.
Description
Alkacon OpenCMS v10.5.4 and before is affected by stored cross site scripting (XSS) in the module New User (/opencms/system/workplace/admin/accounts/user_new.jsp). This allows an attacker to insert arbitrary JavaScript as user input (First Name or Last Name), which will be executed whenever the affected snippet is loaded.
