# CVE-2026-22003: Denial of service in Oracle GraalVM Enterprise Edition > A low-privileged attacker with local access can cause data modification and denial of service in Java SE and GraalVM via difficult-to-exploit flaws requiring user interaction. - **Severity:** Medium 6.0 (`CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:H`) - **Exploited in the wild:** Not known - **Login needed:** Any signed-in user - **Attackable:** Local or same network only - **Victim action needed:** A user has to click or open something - **Fix available:** Yes - **Published:** 21 Apr 2026 - **Updated:** 22 Apr 2026 - **Also known as:** BIT-java-2026-22003, BIT-java-min-2026-22003, BIT-jre-2026-22003, GHSA-q4wq-4whj-cxhx, MINI-wg8q-m759-73h8, UBUNTU-CVE-2026-22003 ## What is CVE-2026-22003? CVE-2026-22003 is a medium-severity denial of service vulnerability in Oracle Graalvm, published on 21 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link. ### Official description Vulnerability in the Oracle Java SE, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Hotspot). Supported versions that are affected are Oracle Java SE: 8u481 and 8u481-b50; Oracle GraalVM Enterprise Edition: 21.3.17. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Java SE, Oracle GraalVM Enterprise Edition executes to compromise Oracle Java SE, 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 creation, deletion or modification access to critical data or all Oracle Java SE, Oracle GraalVM Enterprise Edition accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE, Oracle GraalVM Enterprise Edition. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.1 Base Score 6.0 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:N/I:H/A:H).

What it is: CVE-2026-22003 is a medium-severity denial of service vulnerability in Oracle Graalvm, published on 21 Apr 2026. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link. Exploitation: There is no known exploitation of CVE-2026-22003 in the wild and no public exploit code. Affected packages and fixed versions: - java (Bitnami): affected all versions; fixed in 1.8.0, 8.0.491 - java-min (Bitnami): affected all versions; fixed in 1.8.0, 8.0.491 - jre (Bitnami): affected all versions; fixed in 1.8.0, 8.0.491 Task: 1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies. 2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it. 3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead. 4. Run the tests and summarise what changed and why. 5. If nothing in the project is affected, say so and change nothing.
