The flaw is triggered by calls to vulnerable APIs, such as those exposed by web services or by sandboxed Java Web\u00a0Start applications or applets that load untrusted code. The CVSS\u202fv3.1 vector indicates a low confidentiality impact (C\u202f=\u202fLow), with no identified integrity or availability consequences.", "risk_and_exploitability": "The CVSS base score of\u202f2.9 classifies the vulnerability as low severity. EPSS data is not available, and the vulnerability is not listed in the CISA KEV catalog. Exploitation requires that the attacker already have logon to the infrastructure where the product executes; no public remote exploitation path is documented in the available information. Consequently, the risk is limited to situations where local infrastructure access is possible, but the potential to read confidential application data remains a concern."}}}}, "created": "2026-04-22T02:00:04.892141+00:00", "updated": "2026-04-22T15:15:16.417227+00:00", "vendors": ["oracle", "oracle$PRODUCT$graalvm", "oracle$PRODUCT$graalvm_enterprise_edition", "oracle$PRODUCT$graalvm_for_jdk", "oracle$PRODUCT$java_se"]}
