CVE-2026-22013: Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition accessible data. in Oracle Corporation Oracle Java SE
CVE-2026-22013 is a medium severity vulnerability affecting multiple versions of Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition. It involves a difficult-to-exploit flaw that allows an unauthenticated attacker with network access via multiple protocols to potentially gain unauthorized access to critical or all accessible data. Exploitation requires human interaction from a user other than the attacker. This vulnerability primarily impacts Java deployments running untrusted code in sandboxed environments such as Java Web Start applications or applets, and does not affect server deployments running only trusted code. The CVSS 3. 1 base score is 5. 3, reflecting a confidentiality impact without integrity or availability impact. Oracle has not explicitly stated a patch or fix for this specific vulnerability in the provided advisory, but recommends applying Critical Patch Updates promptly to mitigate risks.

Technical Summary
CVE-2026-22013 is a vulnerability in the JGSS component of Oracle Java SE and Oracle GraalVM products affecting versions including 8u481, 11.0.30, 17.0.18, 21.0.10, 25.0.2, and 26. It allows an unauthenticated attacker with network access via multiple protocols to compromise the product, potentially gaining unauthorized access to critical or all accessible data. Successful exploitation requires user interaction from a third party. The vulnerability applies to client-side Java deployments that run untrusted code within sandboxed environments, such as Java Web Start applications or applets, and does not apply to server-side deployments running only trusted code. The CVSS vector indicates network attack vector, high attack complexity, no privileges required, user interaction required, unchanged scope, high confidentiality impact, and no integrity or availability impact. Oracle's advisory references the April 2026 Critical Patch Update but does not explicitly confirm a patch for this CVE, advising customers to apply updates promptly.
Potential Impact
Successful exploitation of this vulnerability can lead to unauthorized access to critical or all data accessible by Oracle Java SE, Oracle GraalVM for JDK, and Oracle GraalVM Enterprise Edition in affected versions. The impact is limited to confidentiality, with no direct integrity or availability effects. Exploitation requires network access and user interaction, making it more difficult to exploit. The vulnerability affects client-side Java deployments running untrusted code in sandboxed environments, not server-side trusted code deployments.
Mitigation Recommendations
Oracle has not explicitly confirmed a dedicated patch for CVE-2026-22013 in the provided advisory but strongly recommends applying the April 2026 Critical Patch Update and staying current with supported versions. Customers should promptly apply Oracle's Critical Patch Updates as they contain cumulative security fixes that may address this and other vulnerabilities. Since exploitation requires user interaction, educating users to avoid interacting with untrusted Java content can reduce risk. Monitor Oracle's security advisories for any updates regarding specific patches for this vulnerability.
