Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

A stored cross-site scripting (XSS) vulnerability is found in the text sharing feature of FileCodeBox version 2.2 and earlier. Insufficient input validation allows attackers to inject arbitrary JavaScript code into shared text "codeboxes". The xss payload is automatically executed in the browsers of any users who try to access the infected codebox by clicking link or entering share code.
