• CVE-2026-73300: 0.56% estimated exploitation activity in the next 30 days; percentile 46.99 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary A critical SQL injection vulnerability was discovered in Budibase's MySQL integration that allows remote attackers to execute arbitrary SQL commands. Details Vulnerability Type SQL Injection Description The MySQL integration component in Budibase is configured with multipleStatements: true, enabling execution of multiple SQL statements in a single query. Attackers can inject malicious SQL commands through user input fields, leading to complete database compromise. Location Proof of Concept Exploit Impact - Data Destruction: Execute DROP TABLE, DELETE commands - Data Theft: Exfiltrate data via SELECT INTO OUTFILE - Privilege Escalation: Grant database admin privileges - Denial of Service: Disrupt service operations - Complete Database Compromise: Full control over database Remediation Patch Workarounds 1. Temporarily disable MySQL integration 2. Implement web application firewall (WAF) 3. Restrict database user privileges

# Patch Next advisory brief: CVE-2026-73300

Advisory: Budibase: SQL Injection via `multipleStatements: true`
IDs: CVE-2026-73300, GHSA-q6x4-v3qx-85qw
Record: https://patchnext.com/advisories/cve-2026-73300 (revision 3, source checked 26 Oct 2026, 13:01 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Critical (CVSS 9.6)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- npm @budibase/server: affected <= 3.38.1

## Suggested inspection (read-only)
- `npm ls @budibase/server --all`: lists every installed copy and version, including transitive ones. Run in the project root after `npm ci`.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on @budibase/server.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
