Snyk has a proof-of-concept or detailed explanation of how to exploit this vulnerability.
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.

to version 2.9.0 or higher.
io.antmedia:ant-media-server is a media server supporting RTMP, RTSP, WebRTC and Adaptive Bitrate.
Affected versions of this package are vulnerable to Missing Authorization allowing an unprivileged operating system user to connect to the JMX service running on port 5599/TCP on localhost and leverage the MLet Bean within JMX to load a remote MBean from an attacker-controlled server. Exploiting this vulnerability allows an attacker to execute arbitrary code within the Java process run by Ant Media Server and execute code within the context of the “antmedia” service account on the system.
Note
Exploiting this vulnerability is possible when Ant Media Server is running with Java Management Extensions (JMX) enabled and authentication disabled on localhost on port 5599/TCP.
This vulnerability can be mitigated by removing the following parameters from the service file:
-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Dcom.sun.management.jmxremote.port=5599 -Dcom.sun.management.jmxremote.local.only=true -Dcom.sun.management.jmxremote.host=127.0.0.1 -Djava.rmi.server.hostname=127.0.0.1 -Djava.rmi.server.useLocalHostname=true -Dcom.sun.management.jmxremote.rmi.port=5599
