# CVE-2026-73300: Budibase: SQL Injection via `multipleStatements: true`

**Signal:** Critical and remotely reachable. No known exploitation yet, but it is network-reachable without credentials. (Computed from CISA KEV, EPSS and CVSS; not an editorial verdict.)

## Should you act?

- Not in CISA KEV , but CISA’s SSVC assessment records a public proof-of-concept, so attack code exists.
- EPSS 0.6% , percentile 46: FIRST’s model estimates a 0.6% chance of exploitation activity in the next 30 days, higher than 46% of all scored CVEs (low). EPSS is a probability, not a verdict.
- Needs a user to click or open something. Phishing makes that realistic, but it is not wormable.
- Only applies if your dependency tree includes @budibase/server (npm) <= 3.38.1, no fixed version listed . Check your lockfile, including transitive dependencies.

## What it is

Budibase is an open-source low-code platform. Prior to 3.40.0, 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. This vulnerability is fixed in 3.40.0.

## Affected packages

- npm `@budibase/server` <= 3.38.1 → fixed: none listed

## Affected products (CVE record)

- Budibase budibase: < 3.40.0

## Severity

- GitHub_M CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`
- GitHub CVSS 3.1: 9.6 `CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H`

## Exploitation

- CISA KEV: not listed (no confirmed in-the-wild exploitation known to CISA).
- CISA SSVC assessment: exploitation poc , automatable no , technical impact total .
- FIRST EPSS (model of 2026-10-21): 0.56% probability of exploitation activity in the next 30 days; percentile 46.
