An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-22018 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- java (Bitnami): affected all versions; fixed in 1.8.0, 8.0.491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1\n- java-min (Bitnami): affected all versions; fixed in 1.8.0, 8.0.491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1\n- jre (Bitnami): affected all versions; fixed in 1.8.0, 8.0.491, 11.0.31, 17.0.19, 21.0.11, 25.0.3, 26.0.1\n\nTask:\n1. 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.\n2. 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.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-22018/ (Markdown: https://insights.sbomify.com/CVE-2026-22018/index.md)","id":"CVE-2026-22018","markdown":"https://insights.sbomify.com/CVE-2026-22018/index.md","name":"CVE-2026-22018","record":{"aliases":["BELL-CVE-2026-22018","BIT-java-2026-22018","BIT-java-min-2026-22018","BIT-jre-2026-22018","DEBIAN-CVE-2026-22018","GHSA-376j-8f52-gp2x","MINI-2r34-49pj-wj7x","MINI-4pc9-9qrc-xhvf","MINI-5jrm-5jx4-5mhp","MINI-67j2-wmx7-pff7","MINI-6qg6-v39v-54qq","MINI-6v8g-mx49-vj63","MINI-79p4-76jj-p52m","MINI-84v7-g9g7-8676","MINI-8w8q-jwxh-8cm4","MINI-c8hr-8xxp-p4mm","MINI-cgfg-2x95-qfwv","MINI-hr4c-vvwg-vx9j","MINI-hxpm-7mjx-j4xx","MINI-j3h8-c2m9-9p5q","MINI-m33f-m4q2-cm34","MINI-pvx3-p26p-j858","MINI-qhcm-f5j4-c6gc","MINI-qqc6-f55m-xm87","MINI-r7m3-v388-x252","MINI-r8hc-v366-w928","MINI-rfj6-48xf-g964","MINI-vg23-97qj-cvc8","MINI-w5fr-qgjh-6wqq","MINI-w8cq-qm5h-w34q","MINI-wfpm-vw68-c3v7","MINI-xm77-45rq-7qx7","UBUNTU-CVE-2026-22018"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java SE libraries","requires_auth":"none","summary":"An unauthenticated attacker can cause a partial denial of service in Oracle Java SE and GraalVM by exploiting a vulnerability in the Libraries component.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"graalvm","vendor":"oracle"},{"product":"graalvm_for_jdk","vendor":"oracle"},{"product":"jdk","vendor":"oracle"},{"product":"jre","vendor":"oracle"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Vulnerability in the Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition product of Oracle Java SE (component: Libraries).

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 of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle Java SE, Oracle GraalVM for JDK, Oracle GraalVM Enterprise Edition. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also 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.
