Assigner: VulnCheck
Reserved: 10.11.2026 Published: 13.11.2026 Updated: 13.11.2026

NocoDB before 2026.08.0 contains a stored cross-site scripting vulnerability that allows authenticated Creator users to inject script by embedding markup in column or table titles. The Delete.vue confirmation dialog renders these titles through an unescaped innerHTML binding, executing script when a victim deletes an external-source table to steal session tokens from localStorage.
