Title

MariaDB Connector/Node.js: SQL injection through object keys in SET expansion (permitSetMultiParamEntries)

Summary

MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. From 3.2.0 until 3.2.5, 3.3.4, 3.4.7, and 3.5.4, applications that enable permitSetMultiParamEntries can pass objects whose keys are expanded into a SQL SET clause without being processed by escapeId. An attacker-controlled key containing a backtick can close the quoted identifier and cause the remainder of the key to be interpreted as SQL. This can update columns the application did not intend to expose and can append arbitrary SQL with the database user's privileges. The option is disabled by default, and serialized-object handling used when it is disabled is not affected. This issue is fixed in versions 3.2.5, 3.3.4, 3.4.7, and 3.5.4.

Vulnerability from github – Published: 2026-10-08 19:42 – Updated: 2026-10-08 19:42

Summary

MariaDB Connector/Node.js: SQL injection through object keys in SET expansion (permitSetMultiParamEntries)

Details

Description

With the non-default permitSetMultiParamEntries option enabled, an object passed as a query parameter is expanded into a SET clause, each key becoming a column name. The three code paths implementing that expansion built the backtick-quoted identifier by hand and wrote the key out unescaped, while only the value was escaped.

A key containing a backtick therefore closed the identifier, and the remainder of the key was parsed as SQL. The connector's own identifier escaper (escapeId, which correctly doubles backticks) existed but was not called from any of the three sites. This is an incomplete fix of GitHub issue #252, which corrected escapeId itself in 2023 but left these hand-built call sites unchanged.

Impact

An application that enables permitSetMultiParamEntries and passes an object with attacker-influenced keys into a statement such as conn.query('UPDATE users SET ? WHERE id = ?', [body, id]) allows the caller to write columns the application never intended to expose — a role, balance or password column — and to append arbitrary SQL to the statement, since the injected text is not confined to an assignment.

Exposure requires the option to be enabled: it is off by default, and with it off the object is serialised and escaped as a single string literal, so the key never reaches the SQL grammar. Passing a request body into this API is, however, the ordinary reason to enable the option. An application that enables it is asking for keys to become column names, not for keys to become arbitrary SQL.

Resolution

All three expansion sites now route the key through the identifier escaper, doubling backticks before writing the column name. The feature is unchanged for legitimate keys, including reserved words.

Workarounds

Disable permitSetMultiParamEntries (the default), or validate object keys against an allow-list of column names before passing them to query(), until upgraded.
