### Impact When the PostgreSQL JDBC driver is configured with channel binding set to `required` (default value is `prefer`), the driver would incorrectly allow connections to proceed with authentication methods that do not support channel binding (such as password, MD5, GSS, or SSPI authentication). This could allow a man-in-the-middle attacker to intercept connections that users believed were protected by channel binding requirements. ### Patches TBD ### Workarounds Configure `sslMode=verify-full` to prevent MITM attacks. ### References * https://www.postgresql.org/docs/current/sasl-authentication.html#SASL-SCRAM-SHA-256 * https://datatracker.ietf.org/doc/html/rfc7677 * https://datatracker.ietf.org/doc/html/rfc5802

Improper Access Control vulnerability in Apache Commons. A special BeanIntrospector class was added in version 1.9.2. This can be used to stop attackers from using the declared class property of Java enum objects to get access to the classloader. However this protection was not enabled by default. PropertyUtilsBean (and consequently BeanUtilsBean) now disallows declared class level property access by default. Releases 1.11.0 and 2.0.0-M2 address a potential security issue when accessing enum properties in an uncontrolled way. If an application using Commons BeanUtils passes property paths from an external source directly to the getProperty() method of PropertyUtilsBean, an attacker can access the enum’s class loader via the “declaredClass” property available on all Java “enum” objects. Accessing the enum’s “declaredClass” allows remote attackers to access the ClassLoader and execute arbitrary code. The same issue exists with PropertyUtilsBean.getNestedProperty(). Starting in ve...
