Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree -Dincludes=org.apache.flink

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2025-62228, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree -Dincludes=org.apache.flink

Analyze the terminal output to locate any version of Flink cdc pipeline connectors in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 3.5.0), your application is affected.

Note: The mvn dependency:tree -Dincludes=org.apache.flink command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Flink cdc pipeline connectors, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

Apache Flink CDC version 3.0.0 to before 3.5.0 are 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, users are recommended to update Flink CDC version to 3.5.0 which address this issue.
