NocoDB Vulnerable to Stored Cross-Site Scripting via Rich Text Cells

Summary

Rich text cell content rendered via v-html without sanitization, enabling stored XSS.

Details

Rich text in TextArea.vue was parsed by markdown-it with html: true and injected via v-html without DOMPurify. A user with Editor role can inject arbitrary HTML that executes for all viewers.

Impact

Stored XSS — malicious scripts execute for any user viewing the cell.
