CVE-2023-3641Network attack vector

Stored XSS via unsanitized comment fields

Published Jul 12, 2023 · Updated Aug 2, 2024

Cross-site scripting in NodCMS 3.4.1 allows remote attackers to inject script through POST requests to the /en/blog-comment-4 endpoint. The handler accepts comment_name and comment_content without adequate output neutralization, causing attacker-controlled markup to execute when a comment is rendered. Exploitation requires a victim to view the affected comment, enabling limited confidentiality and integrity impact in that victim's browser context.
