The Podlove Subscribe button plugin for web platforms suffers from a stored cross-site scripting vulnerability due to improper input sanitization during page generation. This allows attackers with at least low privileges and requiring user interaction to inject malicious scripts that can execute in the context of other users' browsers. The vulnerability affects all versions up to 1.3.11. The CVSS vector indicates network attack vector, low attack complexity, privileges required, user interaction required, and impacts on confidentiality, integrity, and availability at a low level.

Successful exploitation could allow an attacker to execute arbitrary scripts in the context of users visiting affected pages, potentially leading to information disclosure, session hijacking, or other impacts on confidentiality, integrity, and availability. The impact is rated as medium severity with limited scope and requires user interaction and some privileges to exploit.
