A code injection vulnerability exists in the DsSpelExpressionProcessor#doDetermineDatasource function of the com.baomidou dynamic-datasource-spring component version 4.5.0 and earlier. This vulnerability allows remote attackers with limited privileges to manipulate the StandardEvaluationContext/SpelExpressionParser, potentially leading to partial confidentiality, integrity, and availability impacts. A patch is recommended to remediate this issue.
