CVE-2026-107385 — MariaDB Connector/Node.js: SQL injection in the text protocol when the session uses NO_BACKSLASH_ESCAPES
MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to 3.2.5, 3.3.4, 3.4.7, and 3.5.4, text-protocol escaping always prefixes quotes with a backslash and does not honor the session's NO_BACKSLASH_ESCAPES mode, including in Connection.escape(). When that mode is enabled, the backslash is an ordinary character, so an attacker-controlled placeholder value can close the SQL string literal and inject arbitrary SQL with the application's database privileges. The vulnerable configuration may be enabled server-wide, through connector initialization options, or with an application-issued SET sql_mode; execute() and batch() use binary protocols and are 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.
How the score was calculated
- EPSS 0.4% (30-day exploitation probability)+5
- 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.
CISA SSVC assessment CISA
Three decision points CISA publishes for the CVEs it assesses (SSVC 2.0.3). A stakeholder decision, not a severity score.
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.
- Identify exposed assets running the affected vendor/product/version combinations (Mariadb-corporation Mariadb-connector-nodejs).
- The attack is network-based and needs no privileges: restrict exposure (ACLs, VPN, WAF) until patched.
- No fix documented in the sources: reduce exposure and monitor the vendor advisory.
- 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).
- Look for parameters with command/query metacharacters and unexpected child processes of the service.

What should defenders know first?
CVE-2026-107385 is "MariaDB Connector/Node.js: SQL injection in the text protocol when the session uses NO_BACKSLASH_ESCAPES", 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 7.4 describes technical severity. EPSS 0.44% 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.
