The flaw is a classic example of missing authorization (CWE\u2011862) and could lead to the disclosure of confidential information. The impact is limited to confidentiality, as the attacker gains read access to data rather than full system control.", "risk_and_exploitability": "The CVSS score of 5.1 indicates moderate severity, and an EPSS score of less than 1% suggests a low probability of exploitation in the wild at present. It is not listed in the CISA Known Exploited Vulnerabilities catalog.
