It is a classic case of insecure logging that violates confidentiality by leaking environment details and is classified under CWE-532.", "risk_and_exploitability": "The CVSS score of 3.3 indicates a low impact, and the EPSS score of less than 1% shows a very low likelihood of exploitation as of the current data.
