Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The org.postgresql:postgresql Maven package is vulnerable to SQL injection in versions before 42.2.28, 42.3.0 through 42.3.8, 42.4.0 through 42.4.3, 42.5.0 through 42.5.4, 42.6.0, 42.7.0, and 42.7.1. Exploitation requires the non-default preferQueryMode=simple setting, a numeric placeholder preceded by a minus sign, and a later string placeholder, with both values user-controlled, allowing an attacker to alter the executed SQL. Upgrade to 42.2.28, 42.3.9, 42.4.4, 42.5.5, 42.6.1, or 42.7.2, or avoid preferQueryMode=simple.
