CVE-2026-35218 Details
Description
Budibase is an open-source low-code platform. Prior to version 3.32.5, Budibase's Builder Command Palette renders entity names (tables, views, queries, automations) using Svelte's {@html} directive without any sanitization. An authenticated user with Builder access can create a table, automation, view, or query whose name contains an HTML payload (e.g. <img src=x onerror=alert(document.domain)>). When any Builder-role user in the same workspace opens the Command Palette (Ctrl+K), the payload executes in their browser, stealing their session cookie and enabling full account takeover. This issue has been patched in version 3.32.5.
A stored cross-site scripting vulnerability has been identified in Budibase versions prior to 3.32.5. The issue arises in the Builder Command Palette, which renders entity names using Svelte's {@html} directive without proper sanitization. An authenticated user with Builder access can create entities (tables, views, queries, or automations) with names containing HTML payloads. When any Builder user in the same workspace opens the Command Palette, the payload executes in their browser, stealing their session cookie and allowing full account takeover.
Users can update to Budibase version 3.32.5 or later, where this vulnerability has been patched.
