CVE-2026-28401Network attack vector

Stored script execution via unsanitized rich text

Published Mar 2, 2026 · Updated Mar 2, 2026

Stored XSS in NocoDB before 0.301.3 allows remote authenticated users to execute scripts in other users' browsers via rich text cells. TextArea.vue passes rich text through markdown-it with raw HTML enabled, then inserts the result into the DOM through v-html without DOMPurify sanitization. Exploitation requires Editor access and rich text mode; viewing the stored cell executes attacker-controlled code in the viewer's NocoDB origin.
