It affects versions up to 1.3.3 and allows attackers to inject malicious scripts that execute in users' browsers, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS 3.1 base score is 7.1 (AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L), indicating network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and low impact on confidentiality, integrity, and availability. No patch or official remediation guidance is currently provided, and no exploits are known in the wild.

Successful exploitation of this reflected XSS vulnerability could allow an attacker to execute arbitrary scripts in the context of a victim's browser, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The CVSS score reflects a high severity with partial impacts on all three security properties. However, no known active exploitation has been reported to date.
