CVE-2026-111440 JDBC LogFactory 任意类加载/构造导致潜在 RCE

在 openGauss-connector-jdbc 的 pgjdbc/src/main/java/org/postgresql/log/LogFactory.java 中，LogFactory 根据 JDBC 连接参数中的 logger 类名调用 Class.forName 加载类后，直接反射调用以 String 为参数的构造函数，再转换为 Log。缺少 asSubclassLog.class 校验，非 Log 实现类也会在类型检查前被实例化。因此，当攻击者可控制 JDBC URL 或连接属性中的 logger 类名，且客户端 classpath...

CVE-2026-111440

The openGauss-connector-jdbc driver is vulnerable to unsafe reflection in the LogFactory.java component. The LogFactory uses Class.forName to load a logger class based on the logger class name provided in JDBC connection parameters. Because it lacks an asSubclass(Log.class) check, it reflects and...
