**Name of the Vulnerable Software and Affected Versions** Apache Hive Metastore (HMS) (affected versions not specified) **Description** The issue concerns the use of the `SerializationUtilities#deserializeObjectWithTypeInformation` method when filtering and fetching partitions, which is unsafe and can lead to Remote Code Execution (RCE) since it allows the deserialization of arbitrary data. In real deployments, the issue can be exploited only by authenticated users/clients that were able to successfully establish a connection to the Metastore. From an API perspective, any code that calls the unsafe method may be vulnerable unless it performs additional prerechecks on the input arguments. **Recommendations** At the moment, there is no information about a newer version that contains a fix for this vulnerability.
