The vulnerability has a CVSS score of 9.8, indicating its severity, and has led to data theft and extortion attempts. This incident is classified as a new event in cybersecurity.

Why It Matters

The exploitation of this vulnerability poses significant risks to enterprises using PeopleSoft, as it enables data breaches and extortion.
