Version: 1.0.0
Severity: Medium
CVSS Score: 6.1 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N)

OVERVIEW¶
Reflected Cross Site Scripting (XSS) has been identified.
DESCRIPTION¶
Due to improper output encoding, a Reflected Cross Site Scripting (XSS) attack can be carried out by injecting a malicious payload into the account registration flow.
IMPACT¶
By leveraging the XSS attack, a malicious actor can make the browser get redirected to a malicious website, make changes in the UI of the web page, retrieve information from the browser or harm otherwise. However, since all the session related sensitive cookies are set with httpOnly flag and protected, session hijacking or similar attacks would not be possible.
