The Berg Informatik Stripe Donation plugin (version <= 1.2.5) suffers from a stored cross-site scripting vulnerability due to improper input neutralization during web page generation. This allows attackers with low privileges and requiring user interaction to inject malicious scripts that persist and execute in the context of other users. The CVSS 3.1 vector indicates network attack vector, low attack complexity, low privileges required, user interaction required, and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of other users, potentially leading to theft of sensitive information, session hijacking, or manipulation of web content. The impact is rated as medium severity with limited confidentiality, integrity, and availability consequences.
