CVE-2026-0824Public exploitNetwork attack vector

Stored script execution via unsafe result rendering

Published Jan 10, 2026 · Updated Jan 10, 2026

Stored cross-site scripting in QuestDB Web Console 1.11.0 through 1.11.9 allows remote authenticated users to execute script in a user's browser. The result grid assigns database-controlled column names and cell values to innerHTML, while Quick Vis inserts unescaped column names into picker markup. Exploitation requires privileges to supply crafted query metadata or stored values and user interaction with the affected grid or visualization, enabling script execution in that console origin.
