The Better WishList API by rickonline_nl contains a reflected XSS vulnerability due to improper input neutralization during web page generation. This flaw affects all versions up to 1.1.4. The vulnerability allows attackers to inject malicious scripts that execute when a user interacts with crafted input, potentially leading to partial compromise of confidentiality, integrity, and availability. The CVSS v3.1 score is 7.1, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, and scope change with low impacts on confidentiality, integrity, and availability.

Successful exploitation of this vulnerability can allow attackers to execute arbitrary scripts in the context of the victim's browser, potentially leading to theft of sensitive information, session hijacking, or other malicious actions. The CVSS score indicates partial impact on confidentiality, integrity, and availability. However, no known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance.
