Executive Summary

NocoDB before 2026.06.2 has a stored XSS vulnerability in the PromptWithFields.vue component. Attackers with Creator role or higher can inject malicious markup into AI field prompts. When victims view field configurations, the unescaped field references render as HTML in tooltips, executing scripts in the victim's browser.

Detection Guidance
