This vulnerability in sonalsinha21 SKT Donation (versions <= 1.9) is caused by improper neutralization of input during web page generation, resulting in a reflected cross-site scripting (XSS) flaw. An attacker can craft a malicious link that, when visited by a user, executes arbitrary scripts in the context of the victim's browser. The CVSS 3.1 base score is 7.1, reflecting network attack vector, no privileges required, user interaction needed, and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker to execute arbitrary scripts in the victim's browser, potentially leading to partial disclosure of sensitive information, modification of data, or disruption of service. The reflected XSS nature means the attack requires the victim to interact with a crafted link or page. No known active exploitation has been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch or official fix is available, users should exercise caution when clicking on untrusted links related to SKT Donation. Implementing web application firewall (WAF) rules to detect and block reflected XSS payloads may provide temporary mitigation.
