Vulnerability in the Java VM component of Oracle Database Server. Supported versions that are affected are 19.3-19.30 and 21.3-21.21. Easily exploitable vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Java VM. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Java VM accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
- Base score: 7.5
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 0.41%
- Percentile among all scored CVEs: 33
- Score date: 10/5/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
