This vulnerability in CozyThemes Cozy Blocks (cozy-addons) allows stored cross-site scripting due to improper input neutralization during web page generation. It affects versions up to 2.0.11. An attacker with low privileges can inject malicious scripts that execute when a user interacts with the affected content, potentially impacting confidentiality, integrity, and availability to a limited extent. The CVSS vector indicates network attack vector, low attack complexity, low privileges required, user interaction needed, and scope change with partial impact on confidentiality, integrity, and availability.

Successful exploitation can lead to execution of arbitrary scripts in the context of the affected application, potentially allowing attackers to steal user data, hijack user sessions, or perform actions on behalf of the user. The impact is limited to confidentiality, integrity, and availability with a medium severity rating. There are no known exploits in the wild at this time.
