Low risk21th percentile — higher than 21% of all known CVEs
Summary
NocoDB prior to version 2026.05.1 allowed authenticated commenters to store HTML in row comments, resulting in script execution when other users hovered over the comment in expanded view. Lack of server-side sanitization enabled the injection of malicious code.
Risk Assessment
The organization may be exposed to XSS attacks, potentially leading to user data theft or session hijacking. Malicious code could be executed in the context of other users' browsers.
Recommendation
It is recommended to update NocoDB to version 2026.05.1 or later to eliminate this vulnerability. Additionally, implementing further input data sanitization mechanisms is advisable.
Original NVD description (English source)
NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, an authenticated commenter could store HTML in row comments that executed as script when other users hovered over the comment in the expanded form view. The comment write paths persisted the raw comment body with no server-side sanitisation; the expanded-form sidebar then rendered the stored body and fed its data-tooltip attribute to Tippy with allowHTML: true. Even when the editor stripped script tags at write time, attribute-level payloads re-entered the DOM as live HTML on hover. This vulnerability is fixed in 2026.05.1.
