CVE-2026-61700: CWE-284: Improper Access Control in mariadb-corporation mariadb-connector-j
CVE-2026-61700 is an improper access control vulnerability in MariaDB Connector/J affecting versions prior to 2.7.14, 3.3.5, 3.4.3, and 3.5.9. The flaw allows a rogue or man-in-the-middle server to cause the connector to transmit a local file despite the allowLocalInfile option being disabled, but only the exact file requested by the application can be sent. Exploitation requires an application to actively load sensitive data over an untrusted connection. The issue has been fixed in the specified versions.
AI Analysis
Technical Summary
MariaDB Connector/J versions before 2.7.14, 3.3.5, 3.4.3, and 3.5.9 do not properly enforce the allowLocalInfile=false setting when processing server-initiated LOCAL INFILE protocol packets (0xfb). This allows a malicious or man-in-the-middle server to echo back the filename requested by the client application and cause the connector to transmit that local file despite the disabled option. However, the server cannot redirect the request to arbitrary files and can only receive the exact file the application requested. This vulnerability requires the application to actively use LOAD DATA LOCAL INFILE over an untrusted connection. The vulnerability is addressed in the fixed versions.
Potential Impact
An attacker controlling or intercepting the server connection can cause the connector to send a local file specified by the client application, bypassing the allowLocalInfile=false restriction. The attacker cannot request arbitrary files, only the file the application attempts to load. This limits the impact to scenarios where the application actively loads sensitive local files over an untrusted or compromised server connection. The CVSS score is 3.7 (low severity), reflecting limited confidentiality impact and high attack complexity.
Mitigation Recommendations
This vulnerability is fixed in MariaDB Connector/J versions 2.7.14, 3.3.5, 3.4.3, and 3.5.9. Users should upgrade to these or later versions to remediate the issue. No additional mitigations are indicated by the vendor advisory. Patch status is confirmed by the vendor advisory.
