Description
Apache Flink CDC version 3.4.0 was vulnerable to a SQL injection via maliciously crafted identifiers eg. crafted database name or crafted table name. Even through only the logged-in database user can trigger the attack, we recommend users update Flink CDC version to 3.5.0 which address this issue.
