Threat Intelligence
The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Amendment
This was deemed not a vulnerability.
Overview
Affected versions of this package are vulnerable to Deserialization of Untrusted Data if the attacker is able to control the JDBC URL used or cause the underlying database server to return malicious data.
Mitigation
Apache Jena SDB has been EOL since December 2020, users should migrate to alternative options from the Apache Jena project e.g. Apache Jena TDB 2 or from 3rd party vendors. Users utilizing Apache Jena SDB with mySQL should ensure they explicitly set autoDeserialize=false on their JDBC connection strings. It is also recommended that users ensure that any ability to set the JDBC connection string is limited to appropriate users.
Details
Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.
Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.
