The vulnerability allows an attacker to inject malicious scripts that execute in a victim's browser session, potentially leading to unauthorized actions or data exposure.

Successful exploitation of this vulnerability can result in partial compromise of confidentiality, integrity, and availability of the affected system or user data. The reflected XSS can be used to execute arbitrary scripts in the context of the victim's browser, potentially leading to session hijacking, defacement, or other malicious activities. However, no known exploits have been reported in the wild at this time.
