AnalysisAI

Local privilege escalation to full takeover in the Install component of Oracle Java SE (8u491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1), Oracle GraalVM for JDK (17.0.19, 21.0.11), and Oracle GraalVM Enterprise Edition (21.3.18) lets a low-privileged local user compromise the runtime and take it over with full confidentiality, integrity, and availability loss. Oracle rates it 7.8 (High) and describes it as easily exploitable by an attacker holding only a logon to the host. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to already possess a local logon (a valid low-privileged account) on the machine where Oracle Java SE or GraalVM is installed, and the vulnerable Install component (installer/updater tooling) must be present or invoked on that host - this is a local-only vector (AV:L), so no remote or network path exists. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H = 7.8) is internally consistent and describes a local, low-complexity, low-privilege escalation with full CIA impact - a host-level takeover once an attacker already has a foothold, not a remotely reachable bug. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who already holds an ordinary low-privileged local account on a workstation or shared host places a malicious file in a location the Install component reads, then triggers or waits for the installer/updater to execute it in an elevated context, achieving full takeover of the Java/GraalVM runtime and host-level compromise. No victim user interaction and no network access are required. …
Remediation Apply the fixes delivered in the Oracle Critical Patch Update of July 2026 (https://www.oracle.com/security-alerts/cpujul2026.html); patch available per vendor advisory - upgrade each affected JDK/GraalVM to the corresponding fixed build in its release line. … Detailed patch versions, workarounds, and compensating controls in full report.
