The vulnerability CVE-2025-43837 in binti76 Total Donations (<= 3.0.8) is a reflected Cross-site Scripting (XSS) issue caused by improper input neutralization during web page generation. This allows an attacker to craft malicious input that is reflected in the web page without proper sanitization, potentially executing arbitrary scripts in the victim's browser. The CVSS 3.1 base score is 7.1, indicating high severity with network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, and impacts on confidentiality, integrity, and availability at low levels.

Successful exploitation of this vulnerability could allow an attacker 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 affecting confidentiality, integrity, and availability at low levels. However, no known exploits are currently reported in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider applying input validation or sanitization workarounds if feasible and exercise caution with user-supplied input.
