Summary 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. Details 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. Impact Stored Cross-Site Scripting against any user who views the affected row. Script runs in the NocoDB origin with the victim's session and can read the auth JWT from "localStorage". Authentication and comment permission are required. Credit This issue was reported by "@DavidCarliez" (https://github.com/DavidCarliez).
