Background
NocoDB is an open-source platform that transforms databases into smart spreadsheets, enabling users to manage data efficiently. It allows for collaborative commenting on rows, which enhances user interaction. However, this feature has a vulnerability that permits authenticated users to inject malicious HTML into comments, leading to potential security risks.
Vulnerability Detail
The vulnerability arises from the lack of server-side sanitization when storing comments. Authenticated users can input HTML into row comments, which is then rendered as live HTML when other users hover over the comment in the expanded view. This can lead to Stored Cross-Site Scripting (XSS), allowing attackers to execute scripts in the context of other users' sessions, potentially compromising sensitive information such as authentication tokens stored in local storage.
