Description
Budibase is an open-source low-code platform. Prior to 3.39.18, packages/server/src/integrations/mysql.ts enabled multipleStatements and inserted an unescaped tableName into a DESCRIBE statement. An attacker able to create a MySQL table with a backtick and stacked statement in its name could wait for a Budibase administrator to run schema discovery, causing the second statement to execute. The fix applies quoteMySqlIdentifier before constructing the query. This issue is fixed in version 3.39.18.

Impact

Budibase’s MySQL connector allowed the execution of multiple statements and inserted the table name directly into a DESCRIBE statement without proper escaping. An attacker who could create a table whose name contains a backtick and an appended SQL fragment would cause the connector to run a second, unintended statement when an administrator performed schema discovery. This flaw permits execution of arbitrary SQL commands, potentially allowing data exfiltration, modification, or other database tampering, as reflected by its classification as a CWE‑89 SQL Injection issue.

Affected Systems

The vulnerability exists in the Budibase low‑code platform prior to release 3.39.18. Anyone running Budibase version 3.39.17 or earlier is exposed when the MySQL connector uses the multipleStatements option and the administrator performs a schema discovery operation. Upgrading to 3.39.18 or later removes the vulnerable code.

Risk and Exploitability

With a CVSS score of 7.6, the issue is considered high severity. The EPSS score is currently unavailable, so the present exploitation probability is unknown, and the vulnerability is not listed in CISA’s KEV catalog. The likely attack path requires an attacker to supply a crafted table name and to rely on an administrative action that triggers the dangerous DESCRIBE query. While not trivially exploitable from a remote network location, any administrative access to the Budibase instance or the ability to influence table creation substantially raises the risk of unintended statement execution.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade Budibase to version 3.39.18 or later.
  • Disable the MySQL connector’s multipleStatements option or remove the ability for administrators to trigger schema discovery.
  • Restrict interactive access to the Budibase interface so only trusted administrators can perform schema discovery operations and monitor database logs for unexpected DESCRIBE statements.
