This vulnerability in PublishPress Gutenberg Blocks (<= 3.3.1) involves improper neutralization of input during web page generation, leading to stored cross-site scripting (XSS). An attacker with low privileges and requiring user interaction can inject malicious scripts that execute in the context of other users, potentially impacting confidentiality, integrity, and availability. The CVSS 3.1 base score is 6.5, reflecting 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 could allow an attacker to execute arbitrary scripts in the context of affected users, potentially leading to information disclosure, modification of content, or disruption of service. The impact affects confidentiality, integrity, and availability to a limited extent. No known active exploitation has been reported.
