CVE-2026-107384 — MariaDB Connector/Node.js: SQL injection through object keys in SET expansion (permitSetMultiParamEntries)

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.

Who exploits it and how urgent it is

A 0–100 score combining confirmed exploitation, ransomware and APT use, public exploits, EPSS and severity.

No exploitation signal in the sources consulted so far.
How the score was calculated
  • EPSS 0.4% (30-day exploitation probability)+6
  • Technical severity (high)+6

The score orders the patch queue; it does not replace your asset context (internet exposure, criticality, compensating controls).

Triage

Is it exploited, how likely is exploitation, what does it touch, and how severe do the sources call it.

Remediation

Fixes and mitigations documented by the sources — linked to the original advisory.

No fix documented by the sources we poll. That does not mean none exists: check the vendor advisory.

First 24 hours

Ordered from the record’s own fields — exposure first, because you cannot patch what you have not found. A rule-generated starting point.

  1. Identify exposed assets running the affected vendor/product/version combinations (Mariadb-corporation Mariadb-connector-nodejs).
  2. The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
  3. No fix documented in the sources: reduce exposure and monitor the vendor advisory.
  4. Search available logs for exploit probes matching the vulnerability class (injection), errors and authentication anomalies.

Detection

Read off the CVSS vector and the weakness class. Starting points, not tested rules.

  • Prioritize edge telemetry for the network-reachable component (proxy, WAF, IDS/IPS).

What should defenders know first?

CVE-2026-107384 is "MariaDB Connector/Node.js: SQL injection through object keys in SET expansion (permitSetMultiParamEntries)", rated High. It affects Mariadb-connector-nodejs (Mariadb-corporation); versions are in the scope table. It is not in CISA KEV, which does not rule out exploitation. CVSS 8.1 describes technical severity. EPSS 0.45% estimates the probability of exploitation in 30 days; neither replaces your asset context. First verify whether exposed or business-critical assets run the affected versions, apply vendor fixes or mitigations, and preserve logs for review.
