pgjdbc pads a value shorter than its declared length with bytes of earlier statements (rather than zeros)
pgjdbc, the PostgreSQL JDBC Driver, versions 42.7.4 through 42.7.13 pads a value that is shorter than its declared length with bytes left in its send buffer instead of zeros, and the server stores those bytes as part of the value. The bytes are messages the d…

pgjdbc does not enforce requireAuth when the value excludes every authentication method
pgjdbc, the PostgreSQL JDBC Driver, versions 42.7.11 through 42.7.13 enforce no restriction when the requireAuth connection property excludes all six authentication methods the driver knows, for example requireAuth=!password,!md5,!gss,!sspi,!scram-sha-256,!no…

pgjdbc stores bytes of earlier messages in place of a large value on GSS-encrypted connections
pgjdbc, the PostgreSQL JDBC Driver, versions 42.7.4 and 42.7.5 can send the previous contents of the GSS send buffer in place of the first part of a value on a connection with GSS encryption (gssEncMode=prefer or require), and the server stores the value with…

Silent channel-binding authentication downgrade via unsupported certificate algorithms
pgjdbc is an open source postgresql JDBC Driver. In releases 42.7.4 through 42.7.11, channelBinding=require connections can be silently downgraded from SCRAM-SHA-256-PLUS with channel binding to plain SCRAM-SHA-256 without it, losing the man-in-the-middle pro…

pgjdbc: Unbounded PBKDF2 iterations in SCRAM authentication allows CPU exhaustion DoS
pgjdbc is an open source postgresql JDBC Driver. From version 42.2.0 to before version 42.7.11, pgjdbc is vulnerable to a client-side denial of service during SCRAM-SHA-256 authentication. A malicious server can instruct the driver to perform SCRAM authentica…

pgjdbc Client Allows Fallback to Insecure Authentication Despite channelBinding=require Configuration
pgjdbc is an open source postgresql JDBC Driver. From 42.7.4 and until 42.7.7, 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 authent…

pgjdbc SQL Injection via line comment generation
pgjdbc, the PostgreSQL JDBC Driver, allows attacker to inject SQL if using PreferQueryMode=SIMPLE. Note this is not the default. In the default mode there is no vulnerability. A placeholder for a numeric value must be immediately preceded by a minus. There mu…

TemporaryFolder on unix-like systems does not limit access to created files in pgjdbc
pgjdbc is an open source postgresql JDBC Driver. In affected versions a prepared statement using either `PreparedStatement.setText(int, InputStream)` or `PreparedStatemet.setBytea(int, InputStream)` will create a temporary file if the InputStream is larger th…

SQL Injection in ResultSet.refreshRow() with malicious column names in pgjdbc
PostgreSQL JDBC Driver (PgJDBC for short) allows Java programs to connect to a PostgreSQL database using standard, database independent Java code. The PGJDBC implementation of the `java.sql.ResultRow.refreshRow()` method is not performing escaping of column n…

pgjdbc Arbitrary File Write Vulnerability
In pgjdbc before 42.3.3, an attacker (who controls the jdbc URL or properties) can call java.util.logging.FileHandler to write to arbitrary files through the loggerFile and loggerLevel connection properties. An example situation is that an attacker could crea…

Unchecked Class Instantiation when providing Plugin Classes
pgjdbc is the offical PostgreSQL JDBC Driver. A security hole was found in the jdbc driver for postgresql database while doing security research. The system using the postgresql library will be attacked when attacker control the jdbc url or properties. pgjdbc…

Moderate severity vulnerability that affects org.postgresql:pgjdbc-aggregate
A weakness was found in postgresql-jdbc before version 42.2.5. It was possible to provide an SSL Factory and not check the host name if a host name verifier was not provided to the driver. This could lead to a condition where a man-in-the-middle attacker coul…
