Machine-written summary

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

Apache Flink's flink-table-planner_2.12, flink-table-api-java and flink-table-runtime packages are affected in versions 1.15.0 through 1.20.x and 2.0.0 through 2.2.0. An attacker who has an account with query submission privileges can send crafted SQL queries that inject arbitrary code, which runs on TaskManagers. Upgrade to 1.20.4, 2.0.2, 2.1.2 or 2.2.1, depending on your release line.
