CVE-2026-28357Network attack vector

Credential theft via unsanitized Formula cell HTML

Published Mar 2, 2026 · Updated Mar 2, 2026

Stored XSS in NocoDB before 0.301.3 allows remote authenticated users to steal viewer credentials through a crafted Formula cell. The replaceUrlsWithLink() function converts URI::() patterns to anchor tags but passes adjacent HTML through unchanged for v-html rendering. A Creator must save the malicious formula, and script execution occurs only when another user views the affected table.
