An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-21947 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, 8.0.481\n- java-min (Bitnami): affected all versions; fixed in 1.8.0, 8.0.481\n- jre (Bitnami): affected all versions; fixed in 1.8.0, 8.0.481\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-2026-21947/ (Markdown: https://insights.sbomify.com/CVE-2026-21947/index.md)","id":"CVE-2026-21947","markdown":"https://insights.sbomify.com/CVE-2026-21947/index.md","name":"CVE-2026-21947","record":{"aliases":["BIT-java-2026-21947","BIT-java-min-2026-21947","BIT-jre-2026-21947","GHSA-998g-2mp2-f264","MINI-4j4g-fhv4-q5ph","UBUNTU-CVE-2026-21947","openSUSE-SU-2026:10204-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Java SE JavaFX","requires_auth":"none","summary":"An unauthenticated attacker can modify Java SE data via JavaFX, requiring user interaction in sandboxed client environments.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"jdk","vendor":"oracle"},{"product":"jre","vendor":"oracle"}],"cvss":{"score":3.1,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Vulnerability in Oracle Java SE (component: JavaFX).  Supported versions that are affected are Oracle Java SE: 8u471-b50. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE.  Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in  unauthorized update, insert or delete access to some of Oracle Java SE accessible data. 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).
