[Leonard Xu <leonard () apache org>]

Severity: 

Affected versions:

- Apache Flink CDC (org.apache.flink:flink-connector-mysql-cdc) 3.0.0 through 3.4.0
- Apache Flink CDC (org.apache.flink:flink-connector-sqlserver-cdc) 3.0.0 through 3.4.0
- Apache Flink CDC (org.apache.flink:flink-connector-db2-cdc) 3.0.0 through 3.4.0
- Apache Flink CDC (org.apache.flink:flink-connector-oracle-cdc) 3.0.0 through 3.4.0
- Apache Flink CDC (org.apache.flink:flink-cdc-pipeline-connector-oceanbase) 3.3.0 through 3.4.0

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.
