CVE-2022-39944: Apache Linkis subject to Remote Code Execution via deserialization

The vulnerability stems from unvalidated JDBC URL parameters in MySQL connections. The MySQL Connector/J is known to be vulnerable to deserialization attacks via parameters like 'autoDeserialize' when attacker-controlled data is processed. Since the mitigation involves parameter blacklisting, the function responsible for building JDBC URLs with user inputs (without proper filtering) would be the entry point. This pattern matches common JDBC URL construction vulnerabilities, and the described attack vector (malicious JDBC EC configuration) directly implicates the JDBC URL building process.
